We've had some significant temperature and humidity changes around here in the past 3-4 weeks. After this I have noticed the top outboard edges of my transom (not where the wood is) are separating about 1/8 of an inch. It is where the upper and lower halves of the molds come together.

I really don't want to do major surgery (who does), since everything seems pretty solid back there, other than this. I was wondering if shooting some epoxy down in the crack and clamping it up real tight would work (at least for a while). If this worked for 2-3 years and I only had to do the same thing again later I would be happy. (You can call me bubba).

Additionally, why did this happen. I can't believe Whaler didn't put a layer of fiberglass connecting the upper and lower molds together. I thought they did but it's obvious from this condition they didn't.

I found the same thing on my recently acquired montauk. I repaired it with West System Epoxy and some high density filler. So far, so good.

This is very common I had the same thing on my 15, I took a small screwdriver wedged the crack open filled it with epoxy and then "C" clamped the thing together, I did apply a coat of gel coat later, it was left over from a repair kit,,,why not? Note, this area is not gel coated when it comes from factory, they refer to it as the "green line", you have basically raw fiberglass exposed to the elements.

If you call technical service at BW headquarters, they will fax you a one page drawing entitled "Transom Weld Repair". It is apparently a common problem.

I had my '86 Montauk fixed by a professional fiberglass guy who does the warranty work for our local Whaler dealer. He said that BW used aluminum conduit in the manufacturing process (he assumed to let gas escape), and that it corrodes and expands, pushing the seam apart.

The BW fix is to grind down the fiberglass and lay in 3 new layers.

My transom seam was seperated on both sides..almost 3/16" in places. I had put epoxy & silicon caulk in over the years to keep moisture out. The fiberglass repair cost me about $800 to have it professionally fixed, but it entailed significant work (removing all of the aluminum conduit). It looks better than new, and I don't worry about dumping my '98 Honda (which weighs probably 200# more than engines in 1986!) into the water!
