How did anyone arrive at this .65" figure? Is this for the front of the engine or the back? If it's for the back that sure seems strange how the shaft coupling is considered to be that far out- how do the bolts even fit in?
While I worked at Viking we had perhaps 100 boats that needed new struts- which of course required a full alignment. ALL of them were done on the hard and then allowed to settle in the water before the final. You cannot install a strut with the boat in the water. Not trying to making a argument here. When I set engines/installed shafts and struts for Liberty Yachts new builds we did it on the hard. Never had a issue later, and checking later revealed a dead on alignment.
