    I’ve poured over the parts catalogues this morning. I’m surprised how many differences there are. I had no idea there were three different drive shafts between 58-70. Since I’m building twins and will want a spare lower unit I will need to find three parts motors of the same build. It appears that the easiest solution would be to use 1960-61 40 hp’s since they are the most compatible with the 1958-59. However, I’m not sure if its worth the risk running the small crank powerheads. Decisions, decisions. This was supposed to be easy. 🙂
