I have a pontoon with bf90, today going down lake felt small vibration at half throttle and then motor changed tunes and boat went slower. I advanced throttle motor acc . Fine but went no faster almost like a clutch slipping, rode back to dock about twenty minutes just babied it back trying not to do nothing to damage anything docked it and didn't see anything visually wrong with anything. Putting it on trailer accerlerated hard and it acted fine and loaded it up. Just wondering what to do I just change all the fluids in motor and lower unit so they are fresh and the lower unit was still going into forward and reverse like normal, any ides are useful thanks in advance!
