Transom Shops In the Boston to Cape Cod area?

[Cape Codder]

Hi guys. I'm thinking about having the transom replaced on my 75 20SF. Any recommendations for good transom shops in the Boston area or Cape Cod? Im not looking to go crazy and lift the deck. I just want to raise it to 25" so I can re-power the boat.

Both good guys who do good work for resonable $$$

Thanks for the suggestions. Haven't been able to get in touch with either of them but I got a quote today from a local guy who'll to do the job from the outside and raise the transom to 25" for $3,800. Does that sound about right?

Finally got in touch with one of these guys and he seems pretty knowledgeable. I'd be comfortable giving him the job but but he wants to do it with Vynilester and Penske board. Would you guys consider that a good plan? Sounds like coosa and epoxy is the way to go from what Ive been reading around here.

Penske and Coosa are basically the same thing. Also called Airex Pxc which is made by Baltek.
He wants to use Penske (Airex) because Composites One has it in stock and delivers on the Cape on Thursdays.
They don't stock all that much Coosa. Composites One bought Baltek or something and they now have a lock on the Airex product.
I've worked with legit Coosa and also the Airex (penske) product and they are identical as far as I can tell.

I would also be OK with Vinylester.
Vinylester has a much better secondary bond (new work to old work) than Polyester, which is really only good for new work, or for making parts from scratch. Polyester doesn't stick to old work very well.
Epoxy has the best secondary bond of all, but the slow cure times can really complicate things for a production shop.

I work for a boatyard, and redid my own transom this winter with epoxy, but that was over christmas when we were closed for a month, and I wasn't in a hurry.
I did some of the interior glasswork, and the three knees to the stringers with vinylester, with no issues.
Vinylester is a kind of hybrid resin that cross-links like a polyester and is peroxide cured, but has epoxy molecules in it to keep it from shrinking, to toughen it up, and to make it more waterproof than Polyester.
I use vinylester all the time. Hardly ever use polyester, and use Epoxy only on special occasions.

Poly and MP. Should I walk the other way and find someone willing to do Composite and Epoxy?

I can't and don't do NE America mathematics. Way above my head. However raise it to 26".

Approx $750 total in materials for a 4x8 sheet of composite core (about $350), epoxy (about $300) and glass material (about $100) with about 30 hours of labor... hmm, sounds about right.
What does he propose finishing the outside with?
Spraying awlgrip I'd add another 3-500 to that quote.
A quick roll-on of gelcoat would be in your ballpark.
Labor could be higher overall depending on how easy/hard it is to get the old core out (i.e. falls out or needs to be ground out).

If he's using straight up marine plywood, and cheap polyester resin (I don't recommend it) than it could be a bit cheaper.

Why do you say raise it to 26"? Im looking at 25" motors.
