I am also thinking about raising the transom on my 1968, 13' whaler to accept a 20" shaft motor I just bought from another forum member. I would rather not just stick on the mini-jacker or CMC extensions. Now I am not sure of the integrity of the old wood inside the transom.

I spoke with Wolfgang Unger of
[www.transomrepair.com[/url] and he said he has done several Whalers with the Sea Cast material.

Briefly, he told me these steps to raise the transom: Remove at least 4" of inside material around notch, make mold to conform to transom curve, grind edges (angled scarf) of remaining transom inner and outer "skins" to accept fiberglass skins that will fill old notch area. Layup fiberglass on waxed mold, Put at least a layer of 1 1/2 oz matte and 24oz woven roving for the inner fiberglass. For the mold, the easiest way is to use 1/4" tempered masonite - this will make the curves you need.
Make sure to leave about 3" extra and feather it in to the existing fiberglass, pour in SeaCast material, finish top, Let cure, apply gelcoat.

I know it is a lot of work, but I was wondering if anyone had done this.
Mr. Unger did say he always has encountered rotted wood inside of transoms he has repaired, even the whalers.

Any thoughts ?
Dave

Would not do it unless you have cracks or something else pertaining to rotted wood. Waste of time and money and everyone who sees it will think it had transom issues....hurting resale.

I agree with Nick. I have seen several old 13's where this has been done, and not one of them looked good or enhanced the value of the boat. It is actually a detraction.

Find a nice looking transom bracket, no more than 6" setback, and use that instead. Not all brackets are created equal, so look around for a nice one that will look good on the boat. Use can also just use the 1/2" thick plates.

What are the 1/2" thick plates ? Is that the CMC Vertical Extensions ?

Yes, CMC calls them static lift plates or something like that. I think the only issue involving a plate or bracket on the old 13 is the slight transom curve. Search back through the forum, as there is MUCH discussion on this issue with 13's.
