It is an intermittent problem. It gets spells where at full throttle it will jerk and shake the transom a bit, and the engine rpms will raise but the boat will slow somewhat as if the clutch is slipping. After I got the motor home, I started looking for evidence of the problem, but the clutch and drum seem OK. I found a small wad of seaweed wrapped around the prop shaft between the shear pin and the shaft seal, but could this cause the engine to jerk and the clutch to slip? If it were a steady problem, I'd think that the lower unit was damaged causing binding and clutch slippage. But mostly it runs OK. I've tried all the settings for adjusting motor tilt in case I was having a cavitation problem, no difference. Cavitation would be almost constant I would think. Anybody had similiar troubles?
