This is quite a good write-up of putting in a new engine. I've put a few in and will say, I've never yet seen a replacement engine that did not need some kind of changes to the bed...For any of you interested in also making these modifications I found this amazing write up of someone installing a brand new beta on their boat. modifying engine beds – ¡Viva San Patricio!
Only thing I’m confused about is how he went about installing the 3” lag screws. Epoxy them before inserting it into the new bed? Worried how they will hold over time and if water might leak into the wooden core.
