    I think I sucked up some leaves, please help.

    I caught a glimpse of some leaves on the back side of a wave just before I rode over them. The ski lost power and would not move over idle speed regardless of RPMs. I got it on the trailer and watched the impeller through the intake grate while a very helpful man at the ramp revved it for me. Everything looked normal there. I dunked the back end while strapped to the trailer. First thing I did was look for leaks at the through hull seal. It didn't leak water into the hull, so I'll assume it isn't leaking air into the pump. I started it and all looked normal. When I give it some gas it tries to push a little more water, but no where what it should be.

    Any ideas on what to do without pulling the impeller?

    Look for leaves or debris inside the jet pump with the engine OFF.

    If a flash light and eyeballs does not reveal the problem, then pull the jet pump. If you have the tools and the ski is on the trailer, takes about ten minutes to get the pump off. I have had debris as small as a bottle cap cause cavitation and loss of thrust.

    Just to be correct, this is what needs done? Quote taken from HERE

    The only bolts you needed to remove are the four LONG bolts that clamp the exit nozzle onto the back of the pump.

    Do not remove the nuts from the pump base studs - they need to stay put. The pump base stays sealed to the hull.

    Assuming you have undone the steering and other small connections to the nozzle, you remove the nozzle. Now you simply wiggle and pull on the jet pump body. It will come straight back out of the hull. It often sticks, so be prepared for it to let go!

    If it is really stuck in there, a 2x4 to lever the pump left and right can help. Do not force the pump way out of line to either side, just a little back and forth to loosen it up.

    Now pull the pump straight out. Often the drive shaft will come out too. That is OK.

    The drive shaft can now be pulled straight out of the impeller. Again, it might be stuck, so be careful when it comes free.

    Now, which Polaris model do you have? Is it an SLH?

    You easily can rebuild the stator with new bearings and replacement stub shaft.

    If your existing jet pump stator has five blades, it is made from aluminum. There is a better stainless steel stator that has six blades.

    What condition is your impeller in? If it is badly worn or damaged, then you have some options.

    Let us know what you have now, in what condition, and we can go from there.

    That quoted info is still applicable.

    This thread has video segments showing the Jet Pump Removal process.

    Not trying to hijack the thread here, but how in the world do the bearings come out of the jet pump? I cooked mine today on the lake and all that was left were a few full size bearings and a TON of steel chunks. I can't see a way to take the races out. Thanks for the help. BTW it sounded just like our garbage disposal after my daughter cleans her fish tank. It was so EXCITING!!

    Looked in the Manual in section 10 and see there that driving them out with a long punch should work. I'll try that. Sorry.
