After rechecking ride plate, and repairs in general, I took her out again and creeped the speed up to 40mph! There was severe vibration! I thought I might have hit something, so I immediately put at idle speed and went back to my boathouse and put her up on the lift. I did not find anything out of the ordinary. Ride plate and screws still tight! Hull looked normal.
Will check out position of gate at full throttle, neutral and reverse on Monday!
Does anyone have other suggestions for vibration at high speed?
Thanks,
Ski
