I am repowering with a new Yamaha. The original Johnson was put on with bolts plus a tube of 3M adhesive. It is white in color and
stronger than cement.
Tomorrow I expect to get a call telling me they can't get the engine off. Does anyone have a solution on how you get this stuff off? (I know it is a problem because I once had reason to take the bolts off for an adjustment and I could not move it.

Check out Anti-Bond 2015, p. 417 of the new West catalog. I have no personal experience with it, but it's supposed to debond 5200.

Thank you! I knew I would get help. You live in a marvelous place! I hope you see the bay everyday.

Sounds like 5200, which is a bitch to scrape off.
Problem with many marina installs is that over the years, the bedding compound will breakdown and allow water to penetrate into the wood transom. Better way to avoid this is to oversize drill out the through-transom holes, coat the insides of the holes with epoxy and let dry, then clean out the holes to the proper size and mount the engine. Best way is to oversize drill then pour a solid plug of epoxy, let dry and redrill proper size (learned from a top rated fiberglass repair shop in the area that the above procedure is the _only_ way they mount outboards after replacing the transom. In fact the owner mentioned to me, that he keeps hoping that the new installs _never_ change to his method, he likes the work!)

I am getting a 2 stroke Yamaha 90hp. It is almost 50lbs. lighter than the Johnson it is replacing. I looked into 4 strokes, but the weight factor was too much for my boat. To get to the proper weight window I would have to downsize hp to almost 50hp. Not a good tradeoff.
