1995 XP not accelerating when given throttle.

Recently bought a 1995 XP. Replaced wear ring because old one was past worn out. Took it out for first time on lake and was doing find till I rolled it. Once I made it to shore and got back on it it took some time cranking it to get it started again then when I went to give it throttle it would hardy gain any speed but the engine would rev up just fine and would move fine at idle. Got it back to dock and pulled seat and had very little water in it but temp sensor was unpluged. Didn't find anything in intake and everything looks fine. It felt like a car does when clutch is slipping. Anybody have a clue where to start looking to find the problem? Also any tips on reboarding? Everytime I tried the machine would try to turn over again.
 
Reboarding is a skill that comes with time especially if you are a larger person.
The only thing that will cause the engine to rev and the ski not move forward are a bad wear-ring, bad impeller, stripped driveshaft splines or driveshaft seal leak. The driveshaft seal will also cause sinking if you have the old carrier bearing style which your 1995 should.

Never took on any water while was out. Ran a scope up back of ski and wear ring and propeller both look good. Any easy way to check the splines on shaft without pulling it? Would the seal just go bad from wiping out on it? The seal you're talking about, is that the carbon ring?

Your 95’ shouldn’t have a carbon seal, it should have the carrier bearing.

Splines are pretty uncommon to go bad.

I would pull the pump and inspect the impeller, wear ring and if it has a hull shoe then make sure you use a neoprene seal.
 
Ok. Thanks. Partzilla only has diagram for a 96 so that's where I'm getting carbon ring from and wasn't close to my computer with parts diagram. I see now the carrier. Where would be best place to get a rebuild kit for it or a good aftermarket one? Figure if I'm striping the pump off might as well go ahead and change them out while I'm at it.
 
Rubber boot is only damage I'm finding. Wear ring has minor scratches in it where prop had to cut groves into it when first installed and no damage to prop. The torn up boot is on engine side so shouldn't be affecting ski should it? Also am I missing a seal on the one side of bearing carrier?

RIVA has diagrams for the older skis.
Torn boot just keeps grease in the PTO. Carrier bearing probably just needs grease.

How is your pump sealed to the hull?
 
Was just rtv but have ordered neoprene seal. Do i need to rtv around holes by jet pump when I reassemble? Also would storage compartment being full of water when trying to reboard make it harder. Didn't have gauges in it or access panel to get to wiring so when I dumped it it kinda filled up with water. Wasn't supposed to ride it hard enough to wipe out but you know how that goes.

Yes. Additional water will make it more unstable.

Use the neoprene seal at the hull but pretty sure yours uses a pump extension so that has to be sealed to the pump. Anyplace air can get pulled into the pump is going to cause your cavitation issues.
