Re: Prop shaft / cutlass bearing overhaul
My knowledge is a bit limited but I'm mechanical. The shaft flag must attach to the engine with an egual space all around before bolting the two together. Moving the engine might change that. My stuffing box is attached to the boat with a flexible poly tube so it should compensate a change.
The shaft must enter the cutlass bering, alligned perfectly to minimize wear.
Its hard for the zinc to impede the water from reaching the bearing.
