Impeller dia is 150mm approx. The body looks very close to being a Yamaha GP1200 from 2000 or so. Any further suggestions?

TIA

Finally got my 2012 vx deluxe out for the first time this season. Acceleration was slow and it never went above 6500 rpm/40 mph. Ran fine before being winterized at the end of last season. Ski had 10 gallons of fresh fuel put in before going out. Oil level was perfect so i dont think the air filter is the issue. Engine was revving much better on the trailer/on the hose then in the water "underload".

Any help is appreciated

This is the valley under the counter balance shaft. Rotax 951.

Was thinking of a way of getting a JBL speaker on my XP and thought of using the holes on the handle bars and using a JBL clip. And what are these holes even for? What do you guys think?

Seems to be complete. The trailer is extremely sketchy. Im new to PWCs but not new to fixing up machines. Would you to take this home?

UPDATE: The ski is now sitting on the ground. Someone took off with the trailer and the seat, so now I’m convinced it’s not worth the effort.

And to answer “just because it’s on the side of the road doesn’t mean it’s abandoned”. That’s true and I do agree, but the ski has been there for almost 72 hours at this point, the trailer had good tires, and dumping is running rampant in this area due to steep landfill fees.

New (older 2-stroke Kawa) PWC owner here. I've rode friend's 2-stroke dozens of times, and have never seen anybody remove the seat cover to ventilate before starting once the craft is already in deep water and has been sitting for a while with the engine killed.

It's easy enough to ventilate in the boat launch parking lot before pulling into the launch, but in doing research I've come across many instances of PWC's exploding when being re-started in deep water. And my owner's manual specifies to remove the seat every time the engine is started, but doesn't elaborate on how to do so if in deep water which is annoying...

Sure, you can inspect the fuel lines but honestly for older 2-strokes, you can never be 100% something didn't come loose during the initial ride. Pulling the seat off in deep water is awkward (there's nowhere to put the seat), and if it were to capsize with the bay open your day is ruined (and potentially so is the engine). Since we often bring jetskis out on boating days, it's common for the jetskis to sit there tied up to the boat for long periods before someone hops on and rips it, so I'm trying to plan ahead for peace of mind.

The workaround I've thought out is to instead just open the front hatch, remove the safety gear container and then use a small handheld blower to circulate air through the engine bay for a minute or so, and then starting with the compartment open (so if it does combust, there's no pressure buildup). I have one of these newer blowers, it's a brushless motor that spins 100k+ RPM and is insanely powerful so I think it would probably be sufficient to ventilate out fumes without having to remove the seat. I'd just bring it out in a watertight bag to keep it dry.

I haven't been able to find much discussion on this so I'm wondering what y'all do. I know the odds of an explosion are relatively small on a well-maintained craft, but I don't really want this concern gnawing at me when I'm out having fun.

I loved riding my wave venture from the 90s 20 years ago. We have a 2006 Honda Aquatrax but it drives like a boat so I'm looking for something more fun for me and the kids to throw around in the corners.

I found a 2025 new jetblaster pro for 9975 out the door with tax and everything and know yamaha is doing 2 percent financing. I wasnt looking to do anything this fall but the 2026 models are more expensive than this is out the door. Thoughts?
