Guys,
I just dropped my 06 OBV in the lake for the first time this season. Boat cranked right up, but RPM's won't go about about 2200 RPM's and I never got above about 5 MPH. I had the throttle all the way open and still nothing more than 2200RPM. It appears to idle fine and I let it idle for about 5-8 minutes before i unhooked it from the trailer. Here is what i did to winterize in case that has any affect on what it may be:

  • Change Oil and filter - 5 qts of Pennzoil 15-40
  • Changed Sparkplugs and sprayed fogging oil
  • Fogging oil in carb intake
  • Changed impellor
  • Changed thermostat and seals around thermostat
  • vdrive oil was changed mid season when i bought the boat so i didn't do this at end of season


Any suggestions on what may be causing this issue?

Thanks!!
