Super Jet SN Buildup; Project Undead

[Wiscojet]

Looking through the many SN builds over the last few months has inspired me to attempt to breath new life into my old 650; it has grown tired and haggard through many years of abuse.

The previous owner (poorly) fixed a crack in the hull which is beginning to open up again, and failed to properly seal the screws when he installed a new pump shoe.

The objectives of this build are to:

- Shorten the rear

- Rocker the nose

- Install BOB adjustable foot holds

- Revise the hood

- Add some power:shooter3:

In the last week, I have torn down the ski and started defoaming. I am waiting on the adjustable footholds before I determine how to proceed with the gunwales. I have put a lot of consideration into how to cut back the rear of the ski and decided to go a different direction than anything I have found on here in my searches by reversing the rear angle while cutting 3.5" off the bottom.

I am very new to serious hull modification so I am taking it one step at a time and only hope to have this complete by next May, but I really appreciate all of the inspiration on here. And the wife is hoping this keeps me from buying an AM hull for a couple more years.

VERY NICE!! so if u do the BOB holds that will make 3 of us that have them in a SN. me you and bruceski. personaly you should really do alot of reading about rockering the nose. if u dont plan on doing alot of surf riding or flatwater backflips with a 850cc+ motor and your doing it for looks i think its alot of work for that. to rocker the nose properly you should split the bond line aka remove the top deck from bottom and then cut it all. as far as parts i would recommend (JETMANIAC) hes ing bad ass and a super cool dude 100% legit http://www.x-h2o.com/threads/85372-...S-LIST-New-Used-Yamaha-and-Custom-Build-Parts

other peoples builds i used for mine check them out.

this will help u alot with reinforcing your hull as far as what kinda fiberglass to use and were to use it and proper amount of layers to use and so on.

good luck to you AND HAVE FUN personaly i think the SN built right looks way cooler then a roundnose. and for and A/M HULL (MY OPINON) go with the SUPERFREAK they r really sweet.

just rode mine today and its a pisser. so nice with the wide tray and shortened hull. an 850 motor and a magnum pump sure makes it more fun though.

I didn't do a rocker nose, just filled the area between the front of the ski and the front bumper. While it looks cool, I'll be the first to say it serves no purpose for me. Since I didn't actually rocker it, it rides in the front just like a stock superjet. It also sprays a lot of water in the face though.

I suggest getting a few rideplates to test length with. Right now I have a pro-tec plate I cut down a bit and I can still run wide open.(which is scary on that ss865) It flips off small surf with ease and would probably flip a decent boat wave as well. It's possible it could flip on flatwater with the right rider, but I am not the guy for that.

Bottom line is, cutting the back loosens the ski up very nicely and the wide tray is hands down the best mod I've ever done. The pole on the nose of the ski feels the same as having it in the normal pole bracket position for me.

Good luck on your build, I'll be following along.

Things are not progressing very quickly now that bow season has started and I am focused on that, but there is enough for an update none-the-less. I would like to get the bottom glassed in in the next few weeks so I have been primarily focusing on those areas. I cut the nose and pulled put more rocker in the nose in a similar manner to many of the other build on here, but I wanted to round it out more so rather than pulling up, I used about a 45 degree angle initially so that there was as much force back as there was up. I had every intention of using two part foam to shape the bottom, but while playing around with some foam board I have, I got shape that I was pretty happy with. For the time being I am going to to build the bottom as if I were going to carry the rail all the way around the bow at its old width, but I would like to trim it down once I can finish cutting out the upper hull and get a good sense of what I want to put back in. I am ready to begin construction activities; all of the defoaming, cutting, and sanding are rapidly becoming tedious. finishing forming in the rear and a couple more hours of sanding and I think I will be happy with the lower hull. We are running out of decent weather so it will be time to bring it into the basement soon.

Here are a few pictures to update:


I do not have a heated garage so between the cold and the relatively good snowmobiling season we have had, I have not completed as much of this as I had hoped over the last few months. I am, however, determined to have this thing on the water Memorial Day weekend or very close to it so I have moved it into my basement to keep going. I laid up the lower half of the nose back in November and I am very pleased with how that turned out as well as the rear. The top half of the nose is roughed in, other than the rail. I am not in love with the shape of this area, but it will shed water well and I think that is as important as the look of it. I began chopping the hood this weekend also. Updates should come more regularly now if I am to stay on schedule. I knew what I was getting into when I started this project from looking at other builds, but it's still a load of work, and I am committed to taking my time on each aspect and doing this correctly.

Not a large update, but I feel like I am making steady progress... Nose is glassed, hood is cut, hood-liner is removed, finished trimming the tub, have done a lot of prep sanding for the glass coming up. My goal is to finish all of the major glass on the ski the second weekend in April. Starting to order other goodies which is exciting. The biggest obstacle to me finishing this on time is that we are in the midst of trying to sell our house and buy another.

A month worth of update: hood glassed, hull reinforced, tub foamed, footholds mounted, tub glassed. Every free minute is going to this project, but those are few and far between with work and getting ready to move on the 28th of this month. But I would much rather move a whole ski than my current mess. I am about a week and half behind my desired schedule.

I am pretty stoked on how the nose is turning out. There are a lot of chopped sn's around now, but I don't think anyone has rebuilt the rail. It is probably wasted weight and definitely would not be as strong in theory as the standard chop, but I think it gives it some character.

It was finally a nice enough weekend that I could move my project back outside which is much more enjoyable to work in than the basement. Continued filling and sanding, mounted the footholds, swapped out the cdi for an MSD Enhancer, added another layer of glass to the inside of the pole area, and started work on the new tray for the hood. The breather system will be similar to the one in orangefinger's thread.

Still making good progress, hoping to make at least a shake down run this weekend; the last two weeks have been been better than Christmas with all the parts from Jetmaniac and elsewhere arriving. Motor is essentially assembled waiting on paint to be completely finished before I assemble, base paint is on, pump and midshaft are installed... It's unfortunate that it has to be in the 40's today and 50's all weekend. I normally love Wisconsin weather, but this is getting so old.

And you move in 5 days. So stinking close to having it water ready.

 

[Wiscojet]

It's so close that I don't stop thinking about having this thing on the water at any point during the day.

We've been in the process of moving for about three weeks now so between that, work, and this project, I don't feel like I have slept in a month. For anyone who's wondering how much work this is, doing some simple math, I figure I have close to 500 hours in this now. I am sure I'm not the fastest: this is this first time I've done anything like this, but it's a lot, especially if you plan to cram most of the work into three months.

To save money for this year, I've decided to stick with the stock pole, stock water-box, and not install trim. I will most likely upgrade the water box later this year and the other two next winter.

And you move in 5 days. So stinking close to having it water ready.

Well, worked on it until sun up this morning, slept for two hours and had it fired up. Lots of stuff left to do to finish it, especially cosmetically, but nothing left that would stop me from riding. Hoping to find time to get out tomorrow for break the motor in.

Nice.
