I read the threads recommending the Solas 17/29 impeller. So I got the Service Manual CD and read all the threads again and decided to put gear oil instead of grease in the bearing cavity of the stator. I used a 3# hammer and large 1/2" sockets to remove the bearings and water seals. Cleaned out the old Honda Grease and replaced it with Amsoil 75/90 Severe Gear Lube. Had a hard time getting the front bearing back in to set flush with the stator, otherwise the sequences of putting everything back together went well. Took my new (2005) R-12X with only 3 hours and just one tank of gas thru it to Ute Lake and I could not get the Ski to get past 3000 RPMs. After 5 minutes and restarting it I loaded it on the trailer and ran the motor to flush water from the exhaust and could throttle it up to 6000 RPMs! What gives? Did I possibly ruin or crush the bearings by hitting them too hard to seat them ?:dunno:

Thanks for any suggestions!

try wd-40 in the maint joint like in your owners manual. I have an 04 R12X that had the same thing happen....would'nt go past 3500 RPM......lubing the throttle body cleared it right up.....if you jammed your pump bearing you could'nt even get 3000 out of it....good luck
