FX-1 Removeing The Pump Shoe

[demolition_x]

Its not to late to change if their no good. Which ones should I get? Thanks for letting me know!

This is the one i have used and will be using again. all one piece round body valve. I got mine at home depot for 17 bucks.

When i did my first one way i bought both the square and the round body valves. Filled them both up with water and sat them on my kitchen sink. Almost immediately the square body valve drained out, while the other valve held water and nothing came out. I let the round body one sit on the counter over night and it still had water in it the next day. I thought there was a problem with the square body valve but i returned it and got a new one and the same thing. I have used the round one in my ski for 2 years and it works flawlessly. Bilge is never full when it sits in the water. I mounted mine as close to the front of the ski as possible. Since i ran mine straight out the back i bought a beat up scupper to protect it some what from landings so water doesn't get forced up the tube as much but i doubt it works too well protecting it since its so beat up. That valve has been good and I have one to install in my fx1 project too.

My $0.02 :beerchug:

Thanks for the info demo! I never though about testing them like you did. I will go and get new ones today.

Another thing is if your gonna refoam the tray wont that clear hose you have running to your one ways get smooched together by the expanding foam? Just a thought, you may have all this figured out. I would hate for you to go through all that trouble to have your one ways blocked.

Bah you dont owe me on the ski deal, just messing with you. Id rather pass the deals to someone I know than let them pass.

I thought it foams up quick and soft then dries hard now you got me thinking.

Demo!

I went to H/D to inspect again.


I blew in a square one softly and they leaked. I tried the round ones and they didn't. Its why I went with them first. I like the water test you did and if I were going to leave my ski floating I would think about it more. I have though about putting it in water like it is and testing just to be sure.
Plenty of time to think about it. Not going to foam till much other work is done.

I really dont know if it will or not but I do know that fx1s from the factory have humps on the hull on the lower deck side where the expanding foam expanded too much, you can rub your hand across it and feel them. What you could do is experiment with a hose in a soda bottle, maybe drill the end out where the hose could stick out then pour the foam in. Once it the foam dries try blowing through it. Or just plumb it straight with pvc and be done.

Maybe if you seal off the tube to make it air tight, the pressure will keep it from smooshing.

After 6 hours of grinding and test fitting, the pump is in. I made a couple of templates for ruff fit. Special fx told me to lay the glass on the inside before I start to grind. Glad I did would not want to do it the other way. It also helped in letting me know how far I had gone with the grinding as you see the new glass. I have to say this is turning out to be a very easy mod. A little more glass and I'm finished!

Looks perfect! You'll have to elongate the hole in your Pro-Tec scoop grate, the R&D grates come elongated already and bolt right up. I've seen some folks move the pump forward so that the scoop bolt lines up and it doesn't seem to hurt anything since there's enough slop in the motor mount bolts to allow for this.....only downside is it puts your Factory Pipe chamber closer to your tank.

Nice work so far.......keep grinding

 

[driftmaster]

Well, another nite of grinding. I matched the pump intake to the pump with what I thought look right to my eye. A little more work and it will be time to flip it back over.

I owe it all to you!!!!!!!!

I think we all need to give specialfx a big hug.

Dude, get done already. The weather is gonna be great the next few days, lets go ride.

 

[driftmaster]

I know the bolts will hold it in place. But I wanted it to fit with no wiggle room and the pump was not sitting flush on the mounting tabs as well. I also had some big chunks out of the intake to fix so I went ahead and built it up to be flush with the bottom of the pump. It takes a little more time and work but less silicone will be needed this way. It should make pulling the pump a little easier too.

Few more pix.

Got the holes drilled and the inserts cut in. Hope their in the right place.

 

[driftmaster]

Glassed old bilge holes, going to lower them. Glassed choke and fuel valve holes. Glassed in thru hull tubes. Sanded hole ski with 80 grit.

 

[driftmaster]

Glassed the footholds in place. My two part foam should be in tomorrow,any tips using it would be appreciated.
I need to order some pistons but not sure what to get, any suggestions? The motor has never been rebuilt or apart. I'm thinking going 1st over but do I even need to bore? Where's the best place to get the pistons, gaskets, wrist pins/bearings and seals?

If you didn't have a seizure or anything you probably don't need a bore, just a hone, bore costs more. You may want someone who know what they're doing to take a look at your cylinders before you order pistons though, just in case you need the bore. Alot of people suggest Pro-X pistons, you can buy a whole top-end kit from Parker Yamaha with Pro-X pistons.

Thanks for the info. From what I read the pro-x top-end kit from Parker does look like the best deal to suit my motor and kind of riding. A lot of people seem to be happy with them too. Plus Parker will have the rest of the parts I need. I'm going to try to tear it down tonight. I'll mic and post some pix. I'm thinking I did have a seizure once a couple of years ago but not sure, we'll soon see.

I just watched that video in your sig. Is that you? Thats with no mods to the hull? Pretty sick.
