Transom Height

[ScottM]

Regarding transom height and transom replacement, has anyone simply added a 5" section to the existing notch to raise the height without actually redoing the entire transom? Our 23' Sceptre originally had a 25" transom but the previous owner cut it down to fit a 20" engine. If we repower, we want to fix the height problem and, at a minimum, put it back to the original height. If, for example, the transom is not structurally compromised and does not require total replacement, can a 5" section be integrated into the existing transom and tied in to the plywood core and fiberglass successfully?

My 1986 23' has a 30" transom, and I believe the 1980 boats and up have 30" transom. check out the new boats, they use 30" shaft motors. The problem I have is with twin engines, because they need 25" shafts, that I have but, they are not spaced right so they are too high on the transom causing blow out. This I can tell you the splash well has very little water over it. Good Luck

I went from 25" to 30" when I repowered my '76 SF 23 in 80. I went from a single 200 hp w/25" to dual 140's with 25". It was a combination of oak,cut and fitted across the transom, and aluminum plate bolted through the transom. The aluminum overlapped sides about 5" and the bottom about 10". The fellow that did it was a real craftsman and 23 years later, it is still intact. I am in the process of going back to the 25" with a single 225 Yammy. Goo luck and tight lines....Animal Chris

Hey Animal Chris, I thought once you went up to a 30 transom you were improving the safety of the boat, you say that you are going back to 25? I have a 25 on my 1973 sceptre and I was thinking of building it up. It seems like its not so important after all. What do you think, since you have had it both ways? Thanks Marc

I RE DID MY 23 WITH A 30 “ TRANSOM AND LOVE IT. JUST SPLASHED THE BOAT LAST WEEK WITH A 225 YAMAHA. IT RUNS GREAT AND I DIDN’T TAKE ANY WATER OVER THE STERN RUNNING, DRIFTING OR STOPPING QUICKLY. IF YOU START BACKING DOWN INTO ON COMING WAVES WELL YOU WILL GET WATER OVER THE STERN LIKE ANYONE ELSE WOULD. THE 30” TRANSOM IS THE WAY TO GO.

Rich, I would diffinately go to 30' if your going to redo the transom,those 5 inches will stop some water from comming in. Do you have the original livewell/splaswell?

Marc, I think it will be a toss up, I haven't had any problems either way (Originally powered with a 200 Evinrude x 25"). I have been the original owner (26 seasons) and the boat's "safety" has been one concern I really have never had to worry with. Still rock solid.
Since I will be going back to one engine, I will lose about 1/3 of the weight back there. Also, it will keep the cowling at ± gunwale level (those 2 140's can get quite loud after a 2½ hour run). All in all, it's just taking it back to "original". Nothing like the real deal.
Good Luck and Tight Lines,
Animal Chris
