RXP vibration issue HELP!
I was out on the water two days ago and noticed that 2 times out of 3 that when I exceeded 7800 rpms I felt and heard a light vibration under my feet towards the back of the ski. It felt like something was in my pump or the pump shaft bearing was going out. Needless to say I limped in for a half hour (never exceeding 3500 RPM's) to be safe. Well that was two days ago, yesterday I started taking apart my ski thinking the worst. I started with my pump, when I pulled it off the aluminum nose cone was gone. I found it way up on the pump shaft and pulled it out.
I can get to 8150rpm's but the vibration starts so I lower the RPM's to 7500 and it goes away. I'm not sure where to start looking.
If it's the pump bearing wouldn't I have the wear ring chewed up?
Can the bearing where the driveshaft connects to the motor be the issue?
Or can it be the stock rear motor mounts? HELP......
