SX/SXi/SXi Pro Resto Project - 97 750SXi

Hello everyone my name is Dan, long time rider, first time poster. I had my first chance to ride a stand up probably around 12 years ago and have been hooked ever since. I picked up a mint condition 1997 750SXi about 11 years ago and recently my girlfriend has wanted to get into riding.

I’ve been keeping my eyes out for a while and decided that buying something as a project might be the best course of action with the winter upon us. I managed to pick up a 1995 750SXi for a pretty good price, but it has definitely seen better days… There is no serious damage to the hull anywhere that I can see but it has a fair bit of scratches, chipped paint and sun faded plastics. This is what it looked like when I first brought it home:

I figured that with about 6 months of work time ahead of us we mine as well go all the way. The plan is to fully disassemble the entire watercraft, replace anything questionable, sand and prep the hull right down to the fiberglass, lay new glass in any problem areas and spray new gel coat over the entire body. With a lot of prep work ahead of us I figured it was best to build a stand that I could wheel the ski around on and keep it at standing level. Unfortunately I didn’t document this but it was pretty straight forward. I pretty well just replicated what I saw on google images.

With the stand complete and the engine pulled the ski was light enough for us to carry it downstairs into our basement where we plan to do all the work and keep warm during the winter.

At his point we were ready to get started with component removal and prep. The fuel tank, CDI box, grate, ride plate, pump, drive shaft, etc were all removed.

So far the biggest PITA has been getting the stickers off. They’re quite damaged from the years of sun exposure and they tend to break off in little chunks. The one trick I found was to use the steam from a clothing iron to loosen the stickers up. I’ve tried using a heat gun but the Iron really works wonders, it just takes a long long time and typically leaves sticker residue all over the gelcoat. After getting fed up, I moved on to remove the handle bar pole and the rubber liner around the engine compartment. I still have a few more stickers to remove and lots more sanding but this is how it sits now.

I should make it clear that I have never rebuilt a ski before, nor do I have any substantial experience working with fiberglass. Any advice would be greatly appreciated. Right now my understanding is that I can sand the whole thing down, spray about a gallon of gel coat over the ski, wet sand, polish and call it a day. Is that correct? Furthermore, should areas where I intend to stick hyrdroturf be gelcoated or should I leave those raw?

Thanks for your advice.
 
That ski is what I learned on back in the day, good for you guys!
For the stickers - sounds like you are doing ok with the steam getting the outer parts of the stickers off, for the residue/glue: at HomoDepot/Lowes/etc get a can of xylene (right next to the paint thinner.) Soak a small piece of rag in it, rub all over the glue & give it about 15 seconds to soak in, wet again & scrape off with an old credit card or similar. Go back over with a fresh rag soaked in xylene again & you are done. Is the simplest & cheapest method & will not harm paint or fiberglass (maybe get disposable gloves though.)
As I am not at all a Kawi guy that will be about the extent of my advice on this build though, good luck with it!

Thanks for the suggestion. I have been rubbing a gasoline soaked rag over the sticker residue which softens it up and allows me to scrape it off with a razor blade. It really doesn't work that well and I have quite alot of residue to get off still. I'll definitely have to give that a shot.

P.s. Everyone keeps telling me that superjets are some much better, I would love to try one but I haven't had the chance to compare them and don't really know the difference. The first ski I ever road was an SJ but it was only for a few years, and way too long ago for me to recall the differences. They seem to be hard to find these days.

Those stickers are from a 1995 SXI

I remember what a PITA they were back when new. I used a eraser wheel made by 3M and it worked great. You can buy them online.

Yea I know, the 97 is the one on the right in the first picture. I've owned that one forever, the 1995 is the one we're currently working on. You are right it is a 95 SXi. I actually saw something about these eraser wheels yesterday, I wish I had known sooner!! I'll have to see how much I really need to get off but it may be worth getting still. Do they work really fast or is it still a fair bit of work?

It's still some work, but the drill does most of it. :) I like the eraser because it takes all of the adhesive off clean too.

LB,

That Xylene stuff works so well! Thanks for the tip! That has really sped up the removal process. Jetfiend, I was going to try and eraser wheel but I couldn't find any at the home depot I was at. At this point its more residue removal than sticker removal but I'll be sure to keep it in mind if I have future projects with lots of decals.

I'm glad it worked for you, I have to give my brother credit for that one but pass it on!
I am hoping to do a similar resto-mod to my 96 B1 this winter, will be paying attention to your glass repairs & gel coating of the bottom of the hull.

vomitspot, the last 2 digits of the VIN are 96 but it seems like I can find information on 97 models whenever I look it up. You could be right, either way, all the parts are the same so I guess it's no real consequence.

M5, thanks for the advice. Can I sand right down to fiberglass and spray or do I have to using a sealing primer before laying down the PSX ONE. I'm going to look into it, sounds interesting.

Good results either way. The PPG Rep advised that I could use a tie coat, but it wasn't necessary. Follow the system if you do.
Mine was right over sanded gel coat and it laid down Smooth.

I forgot to mention that they also have a PSX 700 two part that is even stronger than PSXONE.

So I called my local PPG dealer and they told me that the PSX-One wasn't warrantied by PPG for submersible applications. They forwarded me onto my local Marina and they reccomended a bottom coat specific paint by a company called Seak Hawk. They said to start with the non-sanding primer:

and then lay the sea hawk paint ontop. They never gave me the specific model. Anyone have any experience with these brands?

Unless you park your ski in the water year round you will not have a problem with PSXONE. Sea Hawk products are good but you don't need Bottom Paint.

Well I already ordered the sea hawk 2 part epoxy primer and bottom paint. It really wasn't all that expensive. Just adding a bit of glass to the ski this week (will post), and then going to try doing a full prime and paint on the bottom of the hull to see how it works out. Just going to shoot the primer and paint with harbor freight guns and see how it turns out. If it turns out okay I'll probably just use more HF guns to spray the top half too, if not, I'll be looking for recommendations.
