    Cavitation issue

    ...two small children plus 3/4 tank of gas. I'm assuming the additional weight is what was creating the issue but I didn't experience the cavitation at any other time and it seems to be only on one impeller, I believe the port one. No changes to top speed or any other performance issues. Anyone...

    255 cavitation

    ...the back plate between the impeller body and hull and filled it up with sealant and that really helped with the port side but still bad cavitation on the stbd. People have mentioned about the sir clip on holding the carbon ring in place but its a lot of work to get to there. Has anyone else...

    Cavitation Transom alignment question

    Hello, I have a 2013 Yamaha AR192 and first time taking off jet pump due to suspected cavitation (it picks up speed really slowly). With the pump removed I found what I have been told is cavitation burn on the impeller (see pic below) and pitting on the impeller housing so I am replacing both...

    2008 SX230 Cavitation

    ...replaced my impellers and wear ring housings on both sides. I've replaced the gaskets on the clean out port plungers. I'm still getting cavitation when I accelerate. I did not replace any seals when I replaced the impellers because my local shop didn't think I needed to. I also don't get as...

    2021 AR210, slipping/cavitation on take off

    ...a new to me 2021 AR210 with 30 hours on it at the beginning of the season. It now has about 70 hours. I’ve recently noticed it has been cavitation it slipping on take off, especially when loaded or pulling a tube. It’s not terrible and I can back off of WOT to prevent it from happening. But...

    2011 AR240 engine cavitation above 3K RPMs

    Hey Jet Boaters I have a 2011 AR240, all basic maintenance done each season, motors run well; turn on, idle, rev to 3K RPMs, but when I increase thrust on the right engine throttle above 3K RPMs, the right engine loses nearly all power and begins to cavitate pretty significantly. Shaking...

    255xd Any impeller upgrades? And cavitation issues.

    So I pulled my pumps out today for what I thought was a little cavitation at the end of last year. I do have a bit of scarring on both impellers (6GN-R1321-10-00). We do try an wakesurf. But, I also like going fast. We take long rides up and down the lake (lake of the Ozarks). So we need a good...

    FYI for guys that may have cavitation

    I had to replace the Intake in the tunnel due to corrosion and very bad cavitation because of failed sealant. You can see in the pic Yamaha Fixed an issue so the sealant will not pull out any more. You can now fill the void and the mating surface with sealant and that void on the bottom will...

    Buying a used boat with a cavitation issue?

    ...to note that the center bearing was replaced previously on that same side. After replacing the wear ring it he water tested the boat & got cavitation from that side, it was the end of the season so he pulled the boat, wrapped it & left it for this season. He hasn’t had time to get to it this...

    Hard time planing out and cavitation on acceleration

    Hard time planing out with 2008 AR210 unless lots of weight in the bow.. Cavitation on acceleration and really hard time pulling tube/wake board. Is this normal for the AR210. Seems I should be able to pull better.

    Cavitation and rev limiter

    Hey all, I have a 22 ar195 and it started loosing top end speed. Replaced sparks, topped off with 93 and got the bigger air filter. Ran a little better but not quite. Checked the pump and it looks like the impeller has a chip and there Scoring on the wear ring. Question is now, will that cause...

    Cavitation? Constantly have to reset the Plug

    I have a 2013 SX192, it runs great for the most part but it developed a very annoying issue the last 2 seasons. When going to use it I have to constantly pull the clean out plug and re-seat it in order to get the boat to run correctly. Once you do that 4-5 times its usually fine for the day but...

    Think you have Cavitation? Check your seals!!

    ...around 14mph. It got so bad I was nearly fully dependent on my starboard engine to get to plane and get going. Thinking this was a cavitation issue I invested in some Lucky Cones which didn't help. I finally had enough. After scouring through the threads, a few Youtube videos, and some...

    Impeller cavitation?

    I finally put the boat in the water today after installing new impellers. Each motor sounds normal when running individually, but when both engines are started it vibrates and makes bad noise just like when not in the water. (I was in the water) I am wondering if I got impellers on wrong side...

    Getting some slight cavitation. Where should I start? Sealant is hard and flakes off when I touch it… can I clean everything up with a wire brush?

    Transom Plate Alignment Question - Yamaha AR192

    Hello, I have a 2013 Yamaha AR192. I somewhat new to boating and jetboats. I was reading about cavitation and realized that I might have cavitation as the engine rpms got way up, but the boat really doesn't pick up speed so well. So I watched some videos and read some and pulled the jet pump...

    Cavitation Help Needed

    ...it gives a sound pitch change that sounds like air in the jet and feels like I’m spinning my wheels. I believe this is the symptoms of cavitation right? More weight on board slower I have to go. Had 6 adults on board and I could barely get through it to get on plane. Took a good full minute...
