Took a Kawasaki 1500 SXR 4 stroke jetski and instead put a 1100 2 stroke engine in it which came from a ZXI sitdown jetski.
This video covers the entire build process including all steps and parts required.
Please fill free and drop any questions in the comment and I'd love to respond!
*EDIT 8/14/2024*
I ended up going 100p / 95m / 95g / 2.0 NS.
Secondly, her top speed was 55mph. which is plenty fast, but i think i can go up in impellar pitch because honestly right now she feels like a superjet... she kinda wants to just launch out of the water and start doing back flips. So i want to get rid of that thrust and go more towards top end. so instead of a 13/17 impellare maybe ill go likd 15/20 or something? i have no idea yet.
My initial thoughts... LOVE the ski. very playful and light and reminds me of a superjet on rails.
Pretty sure ive got more takeoff power than a stock 1500sxr.

TOP video man, really thanks for share all this process! It's nice to see how the 2 stroke 1100 can survie on the 1500 hulls.. Just a quick question, and maybe because of the video.. It is just my sensation that the inlet/impeller is loosing speed or something? Looks not so fast as expected. Maybe is just this bad feedback from the video. Anyway, congrats for this super detailed video. Apreciated. Regards from Spain ;)!

@stewartsskirestorationhub 3 месяца назад

Absolutely the wrong pitch its only hitting 58mph and it instantly hits rpm limit. Ill be ordering a steeper pitch soon. But im kinda loving the low end thrust this provides, and 58mph is plenty fast to learn the ski on first. It makes it playful like a superjet

@Watercraftspecialist Месяц назад

Ok I have build an 1100 sxr with an 800 hull. I used to have an 1500 sxr also. I don’t like the hull way to big. Engine is great but need a lot money to get power out of it I have 165 psi compression and 44s Mikuni carbs etc etc

@stewartsskirestorationhub Месяц назад

Yeah, its a good secondary ski. Ill always enjoy a smaller hull more. But i wanted a top speed ski of some kind. I wanna hit 60 with it

@scottamberson8259 22 дня назад

How much did it end up costing? Purchase price of hull and everything you did to it. Seems like you're in the ballpark of what a stock 1500 runs speed wise. Gotta be a bunch lighter. 100lbs? Plus, when rebuild time comes around, you'll be way ahead dollar wise. Great job!

@stewartsskirestorationhub 22 дня назад

6700$ on the dot. It could have been much cheaper, but the vforce, mikuni carbs, cf hood, bilet pole drove up the price.... lol. So in retrospect should have i bought a used 1500sxr for like 8k? Propably... but i like doing these things. But yeah, the light hull and s appy 2 stroke honestly makes this thing fun. My budy has a 1500sxr and he loves mine... almost like a different ski entirely. More playful

@ryrystewy1 2 месяца назад

Sooo... i went all out as you can tell. Premium engine parts, manifolds, carbs, head, carbon fiber hood, billet pole... list goes on. And my receipt tally was 6700$ Ive seen used sxr 1500s for around 7500$ so it was cutting it kind of close. That being said, my buddy has an sxr 1500 and he loves how light and playful mine is compared to his.

Found a 1500 hull near me I can get the pump, impeller, and nozzle from the original 1500 worth picking it up for an extra 500?

@stewartsskirestorationhub 2 месяца назад

Its worth it if you dont plan on buying an entire ZXI sitdown. You can use the pump from that sitdown. That being said, im betting a newer pump,impellar, and nozel would be nice. Id say worth it

hard to say, i havent played with a actual 1500sxr, but it felt very playful and i would say the opposite of nose heavy. but i am only comparing it to a superjet and what i imagined a 1500 hull would feel like

@stewartsskirestorationhub 3 месяца назад

@@fomomofo6917 no problem. basically its because you can get the hull for 900$ . and if you can find a cheap sitdown out in the wild, just throw the engine in the ski and you got yourself a very affordable build. The reason why theres alot of these SXR hulls out there with no engines is because Kommander guts those brand new engines and discards the hulls in bulk.

So i swapped to 2.0ns instead of 2.3 and then used a 95 gram spring. Smoothed it out way more. I then did a 95m jet and also improved it. Basically perfect. But i also went from a 110p to 120p and now a 125p and im noticing im going the opposite direction it needs to. I may try going back to 110p. 95m. 2.0ns. 95g spring. And try that out next. Im currently on 95m. 125p. 95g spring 2.0 ns . With 7/8 out on low. And 1/4 out high. High feels insanely perfect now but low feels very doggy. Full trigger pull is fine, but quarter trigger pull feels doggy.

I desperately need a folding rear boarding step on my 1500 SXR. No one will attempt it because of the exhaust in the way. Can't there be a way to get around the exhaust? Possibly use the same format and fabricate the installation to go around the exhaust pipe somehow? If you can do this project it could be mind-blowing for all the big fat riders like myself that love the ski but can't use it far from shallow water! Please tell me what you think.
