I wouldn't trust Git Rot for a transom. You have no clue what you are dealing with until you open the transom up. I had one that the wood was like composte sitting in the bottom and the only thing in the upper 3/4 was fiberglass with nothing between and that was supporting the motor. The 2nd had multiplelayers inside of fiberglass and wood. The layers of fiberglass held the rotted wood in place. I had it on heat lamps for 2 weeks trying to dry it out and I never could get all the moisture out until I removed everything. Git Rot wouldn't have displaced the moisture nor would I have gotten penetration to all the layers of wood. In both my cases I don't think that I would have done anything to harden the transom and it would be just a matter of time before the motor came off.

I've looked into the git rot but the unknown of it scares me. Like was mentioned above, I really need to get my transom opened up and take a look.

Need to start gathering what i need and figure out who borrowed my engine hoist last.

Post pics of the work here if you can, more information is always welcome.

Arjay shipped my direction today, dragging the boat back from the cabin sunday and kids are at grandmas all next week so I can get this show on the road...

Arjay is here, boat is at the house. Picked up some auger bits and a small electric chain saw. I've got a shop vac so I'll make a tube extension that will fit in the transom cavity.

I've never pulled and re-installed an outboard (this large) but I've got a buddies dad coming by that ran a "boat shop" in the 80s/90s. I'm sure he will be a ton of help but when pulling and reinstalling is there anything to watch out for? Other than just disconnecting and labeling everything?

Don't be afraid of using the chainsaw. It makes fast work if it. I tried the auger boots and stuff because I just couldn't bring myself to using the chainsaw. Once I did it went quick until the saw couldn't reach it any more.

Harbor freight sells these blades m.harborfreight.com/6-piece-hss-saw-blade-with-mandrel-set-67224.html and a Dremel tool with a long flexible shaft. That works good to get to the deeper areas

Terrible... Just ferrible.

Appears I have a solid transom now but it was terrible. Lol
