RXP taking on water, need help...
After two years of sitting in pieces in my garage, my '04 RXP is finally painted and assembled. I took it out today to do a maintenance check run and ended up hurrying to get it back on the trailer 10 minutes later.
After backing it in to the water, I ran it on the trailer to make sure there were no leaks. Satisfied, I took it for a quick spin around the launch area. For 5 minutes it did great, sounded good, and rpms were steady. Then all of a sudden the ski started bogging down, but the throttle and rpms were still normal. I turned it off immediately, removed the seat, and heard water gushing in.
I didn't get a good look because at that time I was worried about getting it back to the ramp and on the trailer before it sank. The engine started up and ran like nothing was happening, so I thought it was maybe an exhaust hose or something.
After getting it on the trailer, the water was halfway up the blower. I drained it and ran the motor to pump out the brackish creekwater for a few seconds and then started inspecting hoses. I didn't find anything loose or damaged, so I brought it home and washed it down and ran it on the hose. Motor ran fine, no leaks anywhere inside the hull.
Sooooo, any ideas? Is it my wear ring?
Ski bogs down, rpms normal, ski takes on water somewhere near the back inside the hull, owner freaks out like little girl, puts ski on trailer, no leaks, motor runs fine, brings home, runs on hose, no leaks, posts on greenhulk.net to ask newb questions and beg for help. The end.

Check shaft seal (carbon ring), has to be that........SKI LOOKS GREAT!!!!

sounds like its leaking past the carbon ring or leaking through your exhaust outlet

I just tore my 96 apart and thought "wear ring" and replaced it. As I was putting it back together I noticed that one of my two water exhaust "straws" (siphon tube) was missing so instead of pushing out it was sucking in. I could run maybe 20 minutes and then drain the hull. I believe this happened because one of my guests beat the shit out of the ski.....not anymore!
Not saying that's it, but it is something you can check before starting on wear ring. Alot less work too . Good luck.

Did you notice when hitting the throttle out of the hole it would cavitate? Kinda like spinning tires. The engine revs but the ski does'nt move like it should.

check your shaft seal mine looked in place but the E clip was gone and could hear water running in. glad you have no damage to your ski blew mine up piston siting vertical in block with a big hole in the side i guess that happens when you are running 8000 rpms and suck up water

I took some pictures of the shaft/seal area, please tell me if something doesn't look right. Is there supposed to be a gap between the bellow and support ring??
