Thanks for the answer dave it was a moment where the boat would slow down just a bit I have a pontoon so being on plane is not noticeable. when I slowed the throttle back a little it would not happen. after about two hours the problem seemed to stop. the boat has set idle most of the summer since my health doesn't allow me out when it is really hot but I am going to check the hub. Thanks for the leads. Dave I know you are a guide what are your rates and do you do much in the fall early winter.
