The transom is where the hull and deck meet. Marine putty is used to bond the two together which has cracked over the years. You will need to take a dremel and cut that old putty out to the fiberglass hull and deck, sand smooth and insert two part epoxy back in. Suggest Water Tite which is a little expensive but the best that I ever used repairing those hulls. It is a 24 hour or overnite cure but the strongest of all. I was heavily involved with this boat and sold many of them over the years.

I and many others have had the same issue and, as usual, Dave is right on the money.

Kind regards

It looks like there is wood (plywood) under the putty. Do you just sand off the old putty and replace it or are you replacing the wood also? Also the Water Tite appears to be blue. What do you use to get the scoop back to white?

There's no wood in there, just fiberglass lamination. I had the same problem about ten years ago and gouged it out with a dremel and filled with epoxy. No problems at all since.

I'm kinda new to this so this may be a silly question. Do I just widen out the cracks and then fill them? Or am I sanding down the whole transom edge and rebuilding it? Also how do I handle the blue water tite on white gelcoat?

Dave will give you some great boat specific details, but in general epoxy is designed to fill space, and not act like a glue. It is better if there is 'room' for epoxy to fill, harden, and bond, instead of having a very tight fit and trying to wet the two touching surfaces to stick them together.

Jackdaw;

that is why I like water tite epoxy filler as it does all that. FYI. It worked for me well for years. Now only if a little moonshine might help when making repairs. I use to when in Virginia doing that job. No wonder I am a little crazy.

Once, I went up a mast that a customer had put a lot of drill holes in the mast below the spreaders and the mast failed. Went several slips over onto another boat. A miracle that I was not killed. On my back and the first thing for pain relief was a stinking large stogie but was not able to take it with me when lighted in the ambulance. At the horsepital, doc was trying to write up pain killers. Nope as I had my own cure all. Home made sparkilin peach mountain water from them thar hills chased with mydol. Works great for back pain. I laughed so hard at the look on old doc while the nurses looked at me busting out laughing. Hardy har har

I spoke with the originator of this thread last night along with a couple of other folks for over an hour. Again, I do not divulge who they are, location or any contact information to anyone plus the information is discarded when I end the conversation except for a follow up.

He was advised the original material was marine putty, clean it out with a dremel, sand the fiberglass lips and suggested using Water Tite. I have used that material for many years and yes it has proven to work and never crack again. It is a slow cure and may need several applications. All said and done, the cheapest white paint is white Krylon spray pain for plastics which I advised the owner to cover the boat so not to overspray.

The owner has my contact information for future reference which I asked him not to divulge as I give that out on an individual basis.
