cavitation

I have been reading a bunch of different threads on this issue and understand that the issues could be: cavitation/wear ring/carbon ring/impeller angle/etc. Let me lay out my situation and I would appreciate your ideas/insight: I live at 5800 feet elevation in Wyoming. The lakes we usually...

So I have a problem with my 97 Speedster. I first had a problem with idle not matching and a problem that felt like cavitation which I thought were my wear rings. I fixed the idle problem and installed new wear rings. I tried to take her out the other day and it starts and idles correctly in...

Hello everyone, I got a 2006 4tec Sportster 2 months ago, after trying it once and noticing a low top speed, I took 2 months and worked on everything...finally took it out for a day ride! However, top speed at most is still around 38 mph (GPS). It takes off right away from idle ... so I am...

I'm in the process of replacing wear ring and possibly impeller. I'd appreciate any comments on sealing around ride plate to help with cavitation. Also, at what point should I consider replacing impeller? I can already see it's a bit nicked up.

Good afternoon, Great forum and I've learned a lot about PWC's! I have a "rattle to the bone" sway/cavitation once I hit 4000 rpm's. Replaced the impeller and pump but the problem still lingers. Water was getting in the hull so I yanked the shaft and will replace everything. Just wondering if...

Ok guys, I am new to the forums and have been reading for 3 nights straight about killing some of my cavitation in my seadoo speedster. I have a 2000 seadoo GTI and a 2005 Seadoo GTI and am very familiar with jetski's, but not so much on the Speedster. I am not used to seeing cavitation. I...

Help. I recently purchased a 2008 seadoo challenger 180 and had the following services done. New spark plugs. Oil Change. New Voltage Regulator. New Impeller Boot. First day on the water after these services, I ran out of gas. I knew I was going to run out of gas so I was going FULL THROTTLE...

Hello all, I'm thinking of replacing the impeller boot myself. Can anyone give me a hand with the process? I believe I have to remove the entire pump assembly from the back of the boat to access this part. Is there any tips I should be aware of before starting this? Also, should I address...

I have a 2009 Challenger 180 215. Friday I took it out after replacing a cracked intercooler hose and it ran fine (7800rpm, engine at normal operating level as far as sound goes) today (Sunday) It idled fine but once I got it to about 1/2 the throttle level position and 5500 rpm there was a lot...

I recently bought a Speedster with twin rotax engines. Both have been rebuilt. I rebuilt both jet pumps with new parts and also the carbeurators on port side. With all of that, the starboard pump is cavitating badly at almost any rpm. The splines looked ok on pump end and the carbon seal does...

I had some cavitation so I pulled my pump and found the ring and prop pretty dinged up. It spins freely but it makes a little of a scraping noise when spinning. Is this normal? the machine has 55 hours on it and had a pump oil change about 10 hours ago. I'm going to change the impeller out so I...

Forum, Please forgive me if I am not posting this in the correct section. I have seen Cavitation threads on here and some are closed and I have done the two fixes but still experiencing problems. I am new but have seen and used much of the advice here and am very grateful. Here is what I...

Been having issues with cavitation on start with this boat. I got a Solas Impeller as a replacement and will put that in today. Before I put it in the pump, I wanted some opinion on the existing wearing. I think I maybe ok. It has some groves in it and it still does fit tight. Here...

After doing some heavy research (Thanks mostly to this forum) I found the boat for my Lady and I. We had to drive 5 hrs but I got a killer deal. It's an 05 Challenger 180 with the 215 Rotax. She has 39 hrs on her(verified at the dealership), the owner advertised the boat as having 70 hrs! I...

Hey guys, Just bought this speedster 200 this season with very low hours (16). First several times I've had the boat out its ran perfectly with no noticeable issues. The last 3-4 times I've had it out recently, I've noticed it's having a hard time getting out of the hole onto plane. It seems...

I'm pretty sure its the carbon seal causing this, I think the baffle is no longer providing enough pressure. If I touch the thing while its in the water it starts leaking. My question is: when running, it looks like it has a wobble to it... is the shaft bent, or is this normal? #2 I'm not a...

I've got some cavitation after a friend borrowed the jet ski and claimed he fell off of it into some weeds. I wasn't there so I don't know the whole story. I had replaced the wear ring ~6 months ago, still running the original impeller. When I took the pump off, this is what I found for the...

First off- bought my Islandia this spring, and I have to say its been the best purchase we have made as a family! It has truly been a summer to remember as a family... Okay so lately, when I launch the boat and idle out past the wake zone and put it under power it cavitates. I get 6k+ RPMs...

i bought a 95 seadoo speedster a month ago,, took it in the water once for couple hours,, starbpard engine died and hobbled back on one engine,, had carbs rebuilt by hopefully experienced mechanic (not alot pwc mechanics in my area). went out today sunday and boat wouldnt gain any speed. also...
