I have been trying to align my engine on my hunter 33 (1978). The engine is a Yanmar 2qm20h, and I have been fighting with it for 3 days now.
I have the coupling disassembled, and have tried using a thick pipe wrench levered between the engine block and the fiberglass stringer but i cant seem to get the mounts to move over a bit. All the mounts have been loosened but I think the 30 years of use has made the mounts stubborn.
I will try putting a jack under the engine to relieve stress on the mounts tonight and see if i can push the engine over that way.
Does anyone have any tips? I can see visually the engine flange needs to slide over a millimeter or two to port to line up with the coupling. The engine shaking I was having last season is undoubtedly because of this mis-alignment.
I have bought a flexible coupling (drive saver) between the flange and coupling. With this flexible intermediate plate, can I get away with the gap? or do I still need a .004 inch gap with the feelers (the coupling is 4" diameter).
Any help would be appreciated.
