Brings back memories of 2 years ago when I removed my 4jh-te from my 1987 Bayfield 36 to remove transmission for repair. It went well - just moved it forward and placed It on the cabin sole (with proper supports / reinforcement). My aft - port motor mount needed to be replaced as well due to water rusting it out. Seems to be a common problem! I have a flexible coupling on my shaft and highly recommend it as it makes engine alignment easier by far! Good luck with your project. Looks like you have a nice foundation to work with.
