Upcoming Transom Redo

[Capt Terry]

Thanks Moose, Mitch and DonV for your suggestions-
Right now I am leaning towards increasing the transom from 20” to 22” Why 22” and not 25”? In my 42 years of use, with a Hermco splashwell, and particularly only lake-usage now, the 20” has served me quite well. I only anchor from the bow and keep the stern towards the beach. I have about 2” of clearance now from the ETEC to the transom. A 22” transom with the splashwell drain plug installed, would provide more margin when the heavies are sitting in the stern at anchor. With 22” I can also keep my mechanical steering and avoid a 5” ETEC driveshaft extension.
The next step is building or locating an engine stand for the 418# ETEC.

When I was replacing my transom, I planned on raising it 2-1/2". When I cut the core, I left an extra inch at the top with intentions of trimming it down to 2-1/2". Didn't get trimmed so I have 3-1/2" more than before. All is fine except the hydraulic steering fittings will hit if I try to raise it all the way. I have another inch to raise the new motor, (old one took a fatal crap), and that should correct that issue. You'll like having the extra height whatever you end up with.

My ‘76 Seafari has extruded aluminum trim on the transom cut out. Has anyone found a similar replacement?

That is where ingress of fresh water ruins transoms.
5200 is a friend here and not many other places.

Thx Uncleboo, GFS and Chris for your comments on eliminating the aluminum trim on my transom cutout during my transom resto. There were some CSC suggestions on how I could make some fiberglass sheets to raise the transom 2’’. After seeing the "leave the trim off suggestions" I thought about temporarily forming the height increase with plywood or something, pouring the Seacast, removing the plywood and then wrapping the top and sides of the exposed Seacast with 1708 to get the bullnose appearance that Dirtwheels and Uncleboo have on theirs. Comments? Thx again guys.

Hey Uncle Boo-
Was going through this thread and printed out some of the great tips, when I saw your transom cutout again. Maybe it is the camera angle, but don't think I have ever seen such a thin jackplate. What is the depth of it and manufacturer?
Thx

Vance Mfg. It's a 3" setback.
