The drivesaver was the perfect solution. Not only did it fill the gap between gear flange and shaft coupler, but helps to protect the engine from the shock of hitting a rock or running aground. They retail online for about $180. I found one on Ebay for $60 bucks ... used but otherwise in fine condition.

They make something called a Drivesaver that is a disc of heavey plastic and bolts between the shaft coupler and output flange. It is meant to make up for minor misalignment and lessen vibration. Should be available from a marine store.Hamilton Marine in Maine has it. They have a website.It is about 3/4 inch thick.

You can move the prop coupler up, just maintain a prop puller length between the back of the strut to the front of the prop, 1/4 to 1/2. Be sure the prop will clear the bottom at least a 1/4 of a inch.

I dropped a Graymarine 4-75 into my '49 CC this afternoon. The oil pan on this engine evidently sits a little lower than the previous Gray.

I have about a .75 inch space between the prop coupler and tranny. I know the manual calls for a .002 guaged clearance. I can't move the engine any further back without cutting into a floor stringer, and I would rather not replace an otherwise OK prop shaft just to get one that is .75 inches longer.

Is a commercial solution available or perhaps even a "household" solution? Otherwise I was thinking about getting a slab of alluminum cut and drilled to fit. Thanks SM
