300sx build

[WFO Speedracer]

SLOB thats Seriously Long Overdue Build, here are some pics of the 300sx frestyle boat I am buildingI cut the crazy side pads off and glassed over them.I am going to turf over them like on a js hull.Also a pic of the bow eye bushing,that pin had to go,looks like I need some welding done now the front nose piece is aluminum :slap:

[WFO Speedracer]

here are some pics of the flattened handlepole and the shortened pad as well as the nose piece and cover i made for it,that hole above the new piece is my new handhold for barefooting and will be turfed as will the recessed area on the pole

[PAIR-A-DICE]

What engine are you going with?!?

Might end up sinking more money in that than it's worth if you're not careful.:bigeyes:

Real easy to do that with that particular model, IMO.

[Speedfreak]

I am doing a 300 build up also. The ski I got had a oil tank leak so I had to defoam it to get rid of the 1/2 gallon of oil that soaked up in the foam.

We are thinking along the same lines. I also cut the rails off and I am going to raise them to match the line from the front of the ski. I and removed the front oil and fuel fillers and smoothed the nose piece and I am removing the raised pole section and shortning the pole 2 inches.

I built handholds and I am installing my old set of 24-7 footholds in the ski along with a scupper.

I plan on using the stock motor (chime in here if anything seems wrong) It has .087 clearance and still has 150 psi of compression I am going to mill the head and get an aftermarket exhaust. I am cleaning up the ports and maybe if I can find someone to do it for free Have it ported. I am boreing the nozzle as far as I can and then order a prop from Dave @ impros and have it repitched down a couple of steps. That should be good enough for a freestyle ski for a 5 year old. So far I have only spent $34.00 on the ski I had to purchase a new pump bacause the old owner Rocked the pump and broke a few chunks out of the veins. I also made 0* bars out of the stock ones.

The ski was donated by Terry aka Yah-ki on the board. Thanks again for the gift to he little guy.

The ski at the 1/2 way point defoamed and cut up all it needs now is fiberglass work and put back together.

[WFO Speedracer]

GOING WITH A 550 REED ENGINE AND IT WONT COST ANY MONEY i ALREADY HAVE EVERYTHING FOR IT EXCEPT THE PAINT AND I GET A GOOD DEAL ON THAT AS WELL

[WFO Speedracer]

i THINK i PAID $75.00 FOR THIS ONE QUITE A FEW YEARS AGO,IM USING THE 300 ENGINE ON ANOTHER PROJECT BOAT IM WORKING ON

[WFO Speedracer]

I removed the front cavity where the oil tank went and glassed it up also,I needed more room for my exhaust to go into.I love this little hull it has rear exhaust already,an aluminum handlepole with a slick looking cover,and way more room inside than a js 440 - 550 hull,so far everything is going smoothly.

[WFO Speedracer]

a couple of pics of the engine being mocked up,I am using aluminum on top of the stock mounts to get the correct height these pieces arent quite wide ,long or thick enough but they are close.

[Speedfreak]

I see how you are doing it. I finally made sence out of the pictures...Duhh!!

I was worried that if I tried another motor I would have to reglass the motormounts in there. But I see how it can be done now. Great I will look for 650 superjet. Naaa just kidding a ported 300 with a pipe would be good for a 5 year old.

Do you have a picture of how you removed the oil tank bucket. I cut mine out the other day but havn't glassed anything just yet I am still fitting the scupper and footholds.

[WFO Speedracer]

sure I cut it out but havent glassed it back up yet ,when I do Ill post some pics.

[WFO Speedracer]

I was going to put a 650 or 750 in it butI have too many skis already and thought this would be a good way to make a freestyle boat like I want,by the way where are you putting a scupper in this at,it seems everything is in the way,is it going in up under the rear exhaust?

[djkorn1]

sweeeeeeeeeeet...should be fun!
:woot:

Another question what year is your ski? Mine is a 87 but it doesn't have that bow eye I think I would keep that and get rid of the bar. I will try to get pictures of my smoothed nose piece. I took a few with the phone but you can't tell it is even there I painted it black and now you can't see any detail because of the reflection.


I am either building my own scupper with some rubber sheeting and a piece of alum. for the rear seal. Or getting a home depot one way ball valve. But 1.5 inch pvc will slide right under the exhaust and straight back. If it isn't defoamed but since mine is I am moving the scupper to the center of the hull under the driveshaft and using elebows to connect it to the exit maybe like a side exhaust but on the left side I seen some pictures on here like that but can't remember where.

I would post pictures but I can't seem to get them to upload. WTF?? I can't even get them into the gallery....

Here is a link that I uploaded them to Webshots

[WFO Speedracer]

mines an 87 also ,it did not come with that bow eye.i drilled it and put it there,requires some glass work to the front of the ski though.

[Mark44]

WHY?????????????

Mark44

[Speedfreak]

WHY?????????????

Mark44

Y What???

Why build a freestyle ski out of a 300 sx... Just so that you can "ask" to ride it when it is done.........LOL You know that deep down it's like riding a moped you want to do it you just don't want anyone to know about it... Like bagging the "Big Fish" at the bar... a fun ride you just don't want your friends to know

OR why have a bow eye. So it will fit on the tray and I don't have to get the tripple trailer out of the yard.

[WFO Speedracer]

Its Like A Fat Girl, You Rode One Before You Know You Did, You Just Dont Want Your Friends To Know You Did,to Each His Own I Say If I Want To Ride A 300sx With A 550,650,750,850 Or Whatever In It Thats My Choice,if We All Rode Superjets It Would Be One Boring Ass Place Here And There Would Only Be A Need For One Website

[WFO Speedracer]

man if hes asking why on this one wait till he sees my next build lol

[WFO Speedracer]

Installed This Scupper Today,its Kinda Different But Should Do The Job

[WFO Speedracer]

The engine is in and it looks like it will all just fit in there,actually it has way more room than the 550 hull it came out of.I still have to drill and tap the holes for the engine mounts,lines up pretty well minimum shimming will be required.Trying to get everything in its proper place at the moment,but it looks good so far.:woot: :woot:

[PAIR-A-DICE]

Is that a Coffman's half-pipe? I haven't seen one of those since I sold mine to a guy from Alabama with all my other 550 stuff. :biggthumpup:

[WFO Speedracer]

Thats what it is its damn near indestructable,and shiny

[WFO Speedracer]

This concerns you why? we know you have no interest in this project,kawis or 300sx's:noevil::poke:

[WFO Speedracer]

nonviolent actually, I am just wordering why you continue to stir the pot,really just let it go,I know its not your style but try it sometime ,you might be suprised.

[Wolf Child]

canI have that motor?

[WFO Speedracer]

Have ? no I don't think so.It is waiting on a set of reeds at the moment,I blew out a reed when the crank seals let go and ran across a set on pwctoday a few days ago,they are on there way as we speak.

[Wolf Child]

Have ? no I don't think so.It is waiting on a set of reeds at the moment,I blew out a reed when the crank seals let go and ran across a set on pwctoday a few days ago,they are on there way as we speak.

but it's just a 550 motor.

c'mon...help a brutha out. :Banane09:

[WFO Speedracer]

Let me give you some history here.That engine was probably the first 550 reed in the USA.I was working at the stealership when we got the microfiche in for it,these are released about two months prior to the product being released,I actually got Walter Rainwater at the Kawasaki warehouse to go and pull the parts and see what the differences were between it and the 550 pp engine,then I ordered the parts and put it together,you can't buy an engine from Kawi for any amount of money,just pieces.

[Wolf Child]

so does that mean you'll let me have it? :Banane01:

c'mon... you know you want to.

[spence]

Are the 300 and 650 hulls the same or just look alike?

[Wolf Child]

not even close

[WFO Speedracer]

so does that mean you'll let me have it? :Banane01:

c'mon... you know you want to.

What gave it away?:fart:

[spence]

never seen a 300 in person have the same style kinda

[Wolf Child]

it's a much smaller hull overall. but appearantly it's ALL engine bay. who knew?

[spence]

can a stock one even get like a 200lbs guy on plane?

[Wolf Child]

never riden one. I wouldnt know.

[The Timmer]

all i gotta say is thats one lucky 5 year old...i could only wish stand up skis when i was 5 lol good father

[chad]

you kinda have to rock it and convince it to plane ..

the motor compartment looks huge with the stock 1 cylinder motor in there.

fun boat for kids ~

[Bruins]

Nice. know you got me looking for one to build my son. Post more pics

[WFO Speedracer]

some action shots,flat as a board today not a boat in sight.

[2006superjet]

i have has 440 650sx and 750sxi blaster and now super the 300sx it a decent ski i can load it up easy its only like 200 lbs empty and 2 buy no prob throw it in a big pool or somthing.

the 300 has a lil more power like 3 hp more than the 440 and is more stable. i am 180 and know how to ride and balance so its no problem just hold it full and slowly get up from your knees after its plaining and ur good to go it suck with you get air cause the prop needs to get full again and it is sluggish but its still melow.
i got it for 400 and its clean and runs great i can prob sell it for 400 so im renting it, wish i could say the same for my super. moneypit

[Polish jet pilot]

Cool project...I'd 80hp in that hull would work miracles! Only if the pumps had a larger diameter....

[WFO Speedracer]

Defoaming time,the foam in this thing must have weighed 20 or 30 lbs.While I was in there I also removed the scupper and exhaust tube and ran the exhaust out the hole where the scupper was.I also added a larger bilge tube and glassed up the holes in the bottom,everything protruding through the hull has been sealed with 5200 fast cure.I have already poured the foam and cut it off,its now ready for reglassing .:wiggle:

Look D B PURPLE TURF,don't get excited its coming off.

[afcblink]

So, is this thing on the water yet?

[djkorn1]

I want IT!!!

[SKItarist750]

can a stock one even get like a 200lbs guy on plane?

yes it can! as a matter of fact i rode a 300 stocker a few years back when my 750 was blown up and i was waiting on a crank. i'm about 230 lbs and it got me on plane...it took about 20 secs at full throttle though. :rocketwhore: whenever i would bunny hop it would lose so much momentum in the air that when it came back down, that single cylinder just couldn't keep me on plane. easy to sub though cuz it's so lightweight.

[WFO Speedracer]

Yeah its on the water,not running to well at present,some kind of weird total loss problem,I have to pull the engine and see whats up with it.Been riding the 650sx conversion ski lately.

[WFO Speedracer]

Yep the weird total loss problem turned out to be resistor spark plug caps,that combined with resistor plugs was cutting my spark big time,also it has a setup similar to a Rad cover,you loosen four allen head screws and turn a knob and that turns the stator plate to adjust the timing,thing is the allen bolts were tight but the plate was not locking down.So when I pulled the engine I disassembled the stator plate and took some material off the stator locking plate ,now when you tighten it all down it stays where you put it.This setup is kinda neat because it has no switch,it has an auto switch that senses movement of the crank and turns the ignition on,when the rpms drop below a certain range it cuts itself off.Now I have an air leak at the intake manifold that I tracked down yesterday.its time for some more compression and maybe some more exhaust porting for more bottom end,also the impeller pitch is too high,I have a 15 pitch Skat on the way for it and some reed gaskets.

[WFO Speedracer]

I got the gaskets in today to fix the air leak,so I decided to pull it apart and do the deed.I have been looking for the reed boosters I had to put back in the cages when I take this apart,I looked for quite a while and gave up.When I got it apart I found the reed boosters,they were in the reed cages in the engine duh huh! At any rate I decided to put the bad bones reeds back in and try them again since I had gotten the other problems worked out,I also replaced the hodge podge of bolts holding the intake on with stainless studs and USB nuts,much ,much nicer setup now.Maybe it will get warm enough tomorrow t try it out again.:fingersx:

[WFO Speedracer]

I just got back from riding today,it still did not want to dial in right,I finally decided to disconnect the on and reserve hoses and run them directly to each carb,my bog disappeared as soon as I did that. I started dialing in the high speed adjusters,and got it dead on the money.I still need to install some non resister plugs and open up the plug gap to .050 .It freaking rocks now,I need more compression and a lower pitch prop but its right in there,finally I have the ski I always knew it could be,this thing is so short and light that its a blast to ride,not really squirrelly at all just totally badass! :woot:

[afcblink]

want.

[WFO Speedracer]

Did a few mods to the handlepole today,I shortened the steering up by 1 inch,going to test it out now and see how I like it.The aluminum on the top is just a laminate so I can replace it with something else at a later date,I am looking at carbon fiber sheet and at thin diamond plate,the diamond plate would be cool looking but kind of rough though.The chin pad is just sitting there,its off the thunderjet,I think I will pull a mold and mod one up to fit this pole exactly.

[WFO Speedracer]

Next mod up d -cut ride plate,I think you can do without pics on this one,back to the lake I go yeeeeeeeeeeeeehhhhhhhhaaaaaa!!!!

[WFO Speedracer]

The D-cut works pretty much the same on this as on anything else,nose pops up quicker,maybe a little too quick.At least I have some more leverage on the pole now to keep the nose down,all in all I am pretty happy with it.

[JoeD]

Cool build, I have a 701 going in my 300sx hull sometime this winter. Haven't decided what to do with the pump yet though?

[WFO Speedracer]

Cool build, I have a 701 going in my 300sx hull sometime this winter. Haven't decided what to do with the pump yet though?

I was thinking about that today,the 650-750 pump would mount lower in the hull but,the shaft is much smaller so there is working room inside the driveshaft tube and the engine is mounted on aluminum plates on top of the stock mounts.Seems to me you would just get plates of the right thickness to make up the difference in driveshaft height.Then its just a matter of mounting a 650-750 style bearing carrier to the bulkhead,finding the appropriate length shaft and modding the pump tunnel for a bigger pump,shouldn't really be that hard.I think I have found two more of these locally and I may pass this one onto my son and start on one with a bigger engine and pump.

[Polish jet pilot]

Great project - action photos?

[WFO Speedracer]

Great project - action photos?

post#40 :twak:

[WFO Speedracer]

This ski has now become my sons ski,he really likes my 650SX flatdeck and he likes his 300SX so you guessed it why not combine the two.The plan is to make a semi flat deck with a 650 engine and to mod the pump tunnel to accept the 650 pump.I will also be shortening the handlepole about three inches to get the weight transfer further forward.Here is the progress so far today,more to follow soon as time permits

[WFO Speedracer]

Going a little different route here,I peeled away the SMC from the foam and using some contact cement recycled some of the pieces,they will be glassed at the seams and then glassed over on the back,this gives me somethin nice and flat to lay up against and it should be very strong.I like the way its looking so far.

[WFO Speedracer]

I pulled the handle off and cut it apart today,the actual handlepole is aluminum tubing then a SMC cover goes over that.The end pieces are made to stick into the tubing and then it is welded,anyway I cut three inches out of the tubing and cut the ends out of the tubing I had cut off. I had previously moved the location of the sub plate mount up an inch so in total I am now at -4 inches on the handlepole,I drilled through the tubing and the ends and put a screw through it to keep it in place till I can have it welded,then I cut the cover back 3 inches so it would fit properly.All I have to do now is get it welded back together ,put the cover back on it and finish the bodywork on the handlepole cover.This should make a world of difference in the handling and control-ability of this machine.it rode nose high before and really needed more forward weight distribution.I will post some pics later of the stocker and of this one, but truefully it looks so stock that you wouldn't know anything was done unless you are really familiar with 300SX's.

[subnsxr]

If you pull off the front cover and get a rick roy pole and mount it up front it looks similar to Malone Q8 hull, I'm swapping my SJ RN to the 300sx.

[WFO Speedracer]

Yeah progress is going slow on this one due to the record low temperatures and lack of funds,hopefully some of the 550 SX performance crap will sell so I can get back on it.

[WFO Speedracer]

A little progress on this,glassing glassing and more glassing.Fire ext holder is glassed in,rear exhaust glassed in,holes in the tray are glassed in,tray are is cut out nasty foam removed,crack in bottom of ski has been repaired.

[WFO Speedracer]

This just in PUMP TUNNEL !:woot:

[Matt_E]

Nice work. :veryhappy:

[WFO Speedracer]

It had a few bubbles in it,I just hit them with the die grinder and filled them with cabosil -epoxy,also filled in the areas you could not get to from the top,a little fairing compound and it should be good to go.

[WFO Speedracer]

I did some grinding on the hull today,there is a ledge where the hull is put together at that was holding off the bearing housing from seating squarely,that has been ground down and flattened off.I also had to grind down the top of the bearing housing for clearance.At any rate I stuck it all together and it should be in shimmable range.Time to order some aluminum to fab the new engine mounts out of I suppose.

[WFO Speedracer]

Anyway it rained here all day so I pulled the 300 in the shop and fiddled with it. I mocked up the driveline to see what is what,it looks like I will be using the same thickness of aluminum plates and making them just a little longer. So far everything lines up and is working out great,I moved the resonator to in front of the engine instead of behind it. Gas tank can go back to its stock location but I am saving that till I get it rideable again.I have moved the engine back quite a bit and I have moved the steering up to a -4. What I don't know yet is how all of this is going to work together so I may have to move the gas tank around a bit to get the weight distribution just right.I could also possibly move the battery to the front of the ski if needed.One ride on it will tell the tale I suppose.<!-- google_ad_section_end --> <!-- / message --> <!-- sig --> __________________

[GIL]

Starting to look like the game plan is coming together! Now you are going to run a 148 MAG w/a 12/18.5 and 260psi, right? I hear thats what all the cool kids are doing these days. lol

[WFO Speedracer]

Actually if Dylan was not riding this it would be getting a 720 Rotax with total loss and a B-pipe,but since he is getting this it will be running a 650 with a pipe mod pulled out of my 650SX conversion ski.I guess I am just not one of the kewl kids.I will however be test fitting the 720 for future reference though,this thing would be a monster with the 720 in it.

[Motorheads5]

I thought you were going with a 550 motor in it ?
Looking good on the glass work

[WFO Speedracer]

I am done with 550's , soon I will be done with 650's as well, I am slowly upgrading everything to 750 or bigger.

[WFO Speedracer]

Here are some pics where I mocked up everything today and some pics of the oillite bushings I installed in the handlepole and bracket,also a pic of where I relocated the breather tube on the hood.I have misplaced the center section of the exhaust pipe so it is not in the pics,I did measure off of my 650SX though,the 300 actually has more room for the exhaust than the 650 does,so I can easily install a Westcoast ,Coffman or whatever at a later date.I also had to move the battery box up and over to clear the exhaust pipe and the coupler.

[WFO Speedracer]

I put three layers of glass on the front of the bulkhead then did three layers on the back.Today I popped the holes in the bulkhead for the bearing housing and bolted it up to the support plate-insert holder. I then glassed in the support plate and mixed up some silica to smooth out some places on the pump tunnel.I am also going to use two 550 couplers on this build so I can move the engine forward another two inches.Excuse the funky bolts holding in the bearing housing,I have replaced them with stainless allen head bolts.:woot:

[WFO Speedracer]

I thought it was way too nose light with the 550 engine in it,I weighed it all out , the 650 engine with the stock exhaust and carb is 65.6 lbs, the 550 had a Westcoast exhaust,the Westcoast dual TL,and dual carbs.With all that jazz on it the 550 weighs 69.6 lbs.That weight is with a swiss cheesed engine bedplate an aluminum flywheel and no front cover on the Total loss system.The stock 300 driveline weighs 15.4 lbs,the stock 650 driveline weighs 14.0 lbs.All measurements done on a fairly inaccurate digital bathroom scale.So it looks like I lost 5.4 lbs so far.

[Foximus]

[Insert insult here] and you have bubbles in your glass. :ugh2:

[WFO Speedracer]

[Insert insult here] and you had bubbles in your glass. :ugh2:

Fixed it for you.:lmao:

[Foximus]

k thanks. I am so clumsy in my typoagesings.

[WFO Speedracer]

It would seem I was slightly ahead of the curve on this build, its ok you can admit it now lol.

[SXIPro]

Couple comments:

You say it is too nose light. Maybe pull the d-cut plate and throw a stocker back on. That way you wouldn't have to mess with other stuff.

Also you stated from now on you are gonna go 750 or bigger. That is a great idea. There are sooooooooo many kawi 750s out there that can be grabbed up cheap. It's actually cheaper to buy the whole damn ski instead of hunting for an engine. (I am sure you know that) People are practically giving away 750SS and 750 STS etc right now.

There is a 300SX on my lake and every year I ask the owner if he is ready to sell it. Maybe this will be my lucky year. I want to set it up for my nieces and nephews to kick around on. Wanna get them hooked on standups while they are young.

Really cool build(s). :woot:

[WFO Speedracer]

I have a Westcoast plate for an X2 that I cut down to fit the 300SX,the four rear holes line up, you just have to cut the front of the plate and bolt it on,I will be trying that as well as a stock ride plate without the d-cut. There is some downthrust angle built into the 650 pump setup that I installed ,that should also help keep the nose down somewhat.

[Foximus]

Yo! Is that rectangle tube I see a giant scupper tube? or battery box?

[WFO Speedracer]

Yo! Is that rectangle tube I see a giant scupper tube? or battery box?
Actually the stock water box slides into it and the steering cable comes in there,I will probably remove it but its in there pretty good,I will have to cut it out if I want it gone.

[Foximus]

damn... just slide a ETX15 down in there then.

[WFO Speedracer]

Na I have a battery box all made up that mounts to the rear bulkhead and holds a Jetworks battery.

[WFO Speedracer]

Update time,mounts for the pump are glued in ,waiting on the epoxy to dry then I will glass over the inserts top and bottom to make this as strong as I can get it.I would not suggest to anyone else to do it this way,its time consuming and a PITA,glassing in aluminum bar stock from the bottom would probably be a better option here.And yes I know the driveshaft is not in straight.

[Foximus]

Terry dude...

that driveshaft aint in straight.

[WFO Speedracer]

Terry dude...

that driveshaft aint in straight.

Yeah I know I still have to shim the housing to get it where I want it.

[Foximus]

Yea... but the driveshaft still isnt straight.

[WFO Speedracer]

Yeah I know

[Foximus]

Ok, just wanted to make sure that you know that I know, and we both know.


Do you think Travis knows? We should probably tell him.

[WFO Speedracer]

Ok, just wanted to make sure that you know that I know, and we both know.


Do you think Travis knows? We should probably tell him.

I will PM and let him know.

[WFO Speedracer]

Many thanks to Crammit for the driveshaft that made this conversion possible. I shot a few pics of various stuff, the oversize bilge system, new cooling line, glassed inserts for the pump, the resonator and some other exhaust stuff. I am redrilling the plates I used to mount the 550 in with and using them for the 650, that will get this moving a long a little faster and get it where I can water test it to see whats what. I ended up using a 750 SXI driveshaft donated by Crammit and two 550 couplers to move the motor forward three inches, yeah I know what you are thinking but this is my sons ski and I want it to be well balanced and ridable, if it backflips thats fine , if not thats fine too.

[trd_yota]

so is that a 650x motor in there?

[WFO Speedracer]

so is that a 650x motor in there?

Yes it is, a damn good running one at that. :bigok:

[sjetrider]

Dang, BOB accepts a Kawi 650 set up now?


JK

Seems they liked your build out west huh?

[WFO Speedracer]

According to DK they have never even seen my thread, I am sure they never saw several of the other threads it spawned over at PWCT either, it doesn't matter really, I still have my $3500.00 in my pocket.

[WFO Speedracer]

This is the progress so far today, pump, intake grate and ride plate installed,steering cable lengthened, engine installed, wired , plumbed and electrical box mounted, exhaust run and plumbed , all thats left really is installing the handlepole, and hooking up the start stop switch steering and throttle cables and slapping on a piece of turf.Everything fits like a glove,I would like a little more clearance on the exhaust but I will deal with that later. :woot:

[Cliff]

looking good terry

[WFO Speedracer]

It is alive ! :headbang:

[vitalikol]

It is alive ! :headbang:

Proof of life ???!!!

[WFO Speedracer]

Sorry not taking a vid of it going webowwwwwwwwww webowwwwwwwwwww, maybe I can get Gil to come down and shoot one for me tomorrow.I need to see if I can beat his idling record lol.

[WFO Speedracer]

Proof of life ???!!!

Mad scientist stopped by today and heard it run , so theres your verification, its nasty here today , still debating on whether to do a run or not today.

[vitalikol]

We had almost 80 today and sunny

[WFO Speedracer]

It was about that Friday and Saturday but I had house guests and did not get anything done on the ski till Saturday,I finished it up today but its rainy, cold and miserable, high of 57 here today, windy and overcast,kinda figures doesn't it?
