Re-foaming an Entire Unibond Hull
Posted: Sat May 10, 2025 6:34 pm
I am a new owner of a 1987 Montauk [17]. I bought it with the intent to do some minor restoration and refitting and then use it this summer. I am 19 with a good amount of boat experience and lots of experts on speed dial. I found the transom is water logged from a bad [brass] drain tube—which is common.
The foam in the transom is wet. I know because I took two samples of it by drilling holes. There is also a large soft spot in the floor by a mount for a leaning post, and another one around the hole for the fuel lines into the [rigging] tunnel.
I plan to remove the console and about everything else in the cockpit.
Q1: should I re-foam the whole boat and fix the transom?
Q2: or should I inject epoxy into the soft spots on the deck, replace the drains, let the transom [remain untouched]?
Transom feels solid but I know the foam at is wet. I have 28 days of completly free time before the summer starts. By then I want to be working on the interior and [rigging] controls.
I am a real novice. I just sold my 2001 SPORT 13.
