I removed a 165hp inline six GM engine from my boat. I removed the OMC bell housing or adaptor housing as some call it. I removed the coupler and flywheel. My intermediate housing is ready to install. Bell housing and coupler bolted up. The engine I installed these to is a 165hp inline six GM. This engine had mercruiser parts at the rear of the engine, engine support and coupler. I bolted on the OMC coupler and installed the bell housing. I was just test fitting the parts. When I went to install the intermediate housing the splined shaft fit perfect into the coupler, but it bottomed out and there is a 5/16 gap between the gasket surface of the bell housing and the intermediate hosing. I removed the bell housing and fit the intermediate housing to it with a few nuts.I then tried to fit both them to the coupler and again the shaft bottomed out and the 5/16 gap was sill evedent between the bell housing and the rear of the engine block. I did not change the flywheel from the mercruiser application. The flywheel I took off my old engine looks identical to the one that is with the engine I am installing. Some suggested that I put my old flywheel on. Is it possible that my flywheel may sit deeper into the crankshaft surface? I just cannot figure out what to do to get these housings to fit flush. Both engines, the one I removed and the one I hope to install are from the same time 1970-1979 Blocks are identical except for the parts. I forgot the placement of the OMC coupler. Is it mounted on the flywheel or under it? I know the coupler must sit a little further away to make up the gap. Any suggestions or help would be much appreciated. At this point I'm stuck
