1997 GSX I’m having trouble keeping it idling I have to hold the throttle in a bit in order to keep it running but when I go WOT it goes no problem and easily reaches top speed but when I let go of the throttle and comes back to a idle it dies could this noise be related to that? I’ve already been playing with the low speed screws and idle screws and it’s gotten better but still won’t idle right. Last I checked compression it was 148 both cylinders

2005 RXP 215 SC, she’s on 248hrs run time had her since 120hours 5 years ago. SC rebuilt 2 years ago and haven’t used it since as seasons been awful. Will have to treat her with a new impeller.

Also any suggestions what I could do to this ski, engine-wise or electronically (modifications). Thanks.

What are these called and where do I buy them? Thank you!

Another amazing day in the water today 🫡🤝

This is my friend's 2016 130 GTI SE with just shy of 80 hours. I was not there when it quit but the story I got is that he jumped a wave and the engine shut off instantly upon landing, never to start again. There were no prior warnings on the dash, no lights, no beeping, nothing. It was towed to the nearest marina and they never exceeded 15kmh. The first thing I found when looking at it is a negative battery terminal so loose that it was about to fall off. I thought for sure that was the issue but no, the starter engages but the engine does not spin at all. I checked the intake for something jamming the impeller but it is completely free of obstructions or debris. Battery voltage is at 12.8v. I connected a jumper pack to keep the voltage up yet the starter pulls so much juice that the ski entirely shuts off after 2-3 seconds of pressing the starter button. I pulled the sparkplugs and found the plug of cylinder #2 to be stripped and impossible to get out. I know it was not this way before as I am the one that winterized this ski last year. At this point, I am very much fearing a catastrophic failure of cylinder #2. Is there a spot on this engine that allows us to either put a socket or a wrench to try and spin the engine by hand? This would be my next step before looking into pulling the head off. What do you guys think of this? Thanks

I have seen people install their tow valve in either spots. Is there one that is better or worst than the other? Is is simply a matter of preferences? Thanks!

So much spark has been sitting in the garage for 2 years with the lid not screw on it.

I did maintenance on it this years, when I try to put the lid back on, there is a 1 centimeter gap on the sides, making it very difficult to screw it. I'm pretty sure this is not normal.

Any advice on where to check and the correct method to put it back? Like front first or rear first?

Here are some photos.

For context, engine got flooded, I emptied the water out by taking spark plugs out and removing the water, good news the engine will crank, but it won’t fully start up. The video above is what happens. Does anyone have any insight on it? I assumed it’s either smth with the ignition and or an electrical connection is corroded/rusted so it won’t fully spark.

I'm wondering what a fair price is for my machine. I bought it new at the dealership at the end of the season in 2024 and rode it some, but then moved to a ski boat in 2025. I tried to sell it at the end of 2025, but felt the offers were way too low. I'm looking to sell it for a reasonable price, but I'm not sure what that is. Here's my description:

Bought a used RXT and I just want to clean it up a little bit.

It was a nice clam moring so I took one of the 300s with a few Rive Racing Mods out.

I’m wondering if anyone has a 3d file for this part, mine fell off a few years back when I flipped the jet ski. I am capable of buying this one as it’s only $25 but it would be way easier to just print from a scan file if anyone has it. (plus need an excuse to print something)

To to give some context, we were using the jet ski for about half an hour, and after that we fell off of the ski. got back on the ski and then it wouldn’t start and showed “engine” and now when the key is in with the engine cover off and plugs out it shows “sensor”

so we took it back out and we’ve now started to try and diagnose the problem. we have:
-Taken the Starter motor out and Checked to see if it spins freely and it does.
-Changed the Battery.
- Tried bridging the solenoid to see if the solenoid was the problem but still does not turn over after bridging.
-checked the flywheel after taking the motor out to see if it spins freely and it does.
- cranked the engine over and the engine isn’t seized it just seems to not be getting enough oomph to crank over quickly like it should be doing, almost like it’s being restricted in some way.

any help with getting this back up and going would be greatly appreciated :)
