If the wear ring is installed wrong or the impeller is full of debris this will be the result. look close at the wear ring for scrape marks from the propeller OR are you missing carpet off the rungs of the trailer ?

SOURCE: Driving 65 MPH and engine rpm goes to 7K. Not in O.D. light comes

sound to me like it maybe a faulty sensor in the transmission. take your car to someone with an ODB reader and see if a transmission fault is indicated. you may have to take your car to a transmission shop.

Will only get up to 10 mph but RPM's are up to 8000. Impeller in good shape. No exhaust alarms. Newbie to waverunners.

I just had one do basically the same thing. I had to replace the impeller. It felt like a clutch was slipping. If they get any dings or nicks or anything in the impeller they will not getup speed at all.

Have you done a compression test on all cylinders? My guess is you have a dead cylinder (no oil to one or more cylinders causing loss of power). If the compression test passes (all cylinders equal and higher than 100-110 psi) you have a restricted exhaust from a failed catalytic converter that has broken apart.
