DONE!!!

It's has been a little over a year but I am finished. The transom was rotted and I figured I couldn't tear it up any more than it was. I did a SeaCast repair on the transom. I beefed it up with additional stringers. I also upgraded with new Garmin units, MinnKota Maxxum, Bob's jack plate, hydraulic steering, and blinker style trim and jack plate controls.

Hello Chobeemauga. Although this thread is a year old I am very impressed with your work and looking to use it as help on my 190dc transom project. What model is your single console ? Are you still using it and happy with the repairs? Would you be open to questions? I am lacking in fiberglass work experience but trying to read up on it. Thanks

OK I've read and read now for the start of questions. The sponsons how did,does water get in there? Aren't they sealed? The transom seams vulnerable mine has 10 holes though it. Was there a mid floor in sponsons originally? What type of foam did you use? The fiberglass panels you used did you make these or buy them? How many layers of what type glass? Here is a picture of the inside of my transom where lower jackplate bolts ripped/ pulled in.

Water got in the sponsons because the transom wood is not fully encapsulated and the moisture it soaks up runs in there. There is a photo of the fiberglass between the transom cavity and the sponson. The fiberglass did not encapsulate the transom completely.

Every hole in the transom is a potential entry point for water in the transom wood or/and into the bilge.

The sponsons, as best I remember had 3 compartments. I used regular spray foam. I would not use it again. I cleaned out the foam in the top sections and left it out.

I made the glass panels to seal the sponsons. I also laid some on wax paper and let it cure so it would be rigid enough to keep shape when glassed into place.

I bought all my supplies from SeaCast. They sell fiberglass fabric, resin, and the transom repair mix.

You can lay a patch of fabric and resin over the transom holes from the inside. So lay the patch inside the transom cavity. When you pour the cavity with the SeaCast you will have to drill the holes for the motor after it cures. Inside the transom use a backing plate for bolt heads. See in some of photos. I used an upper and lower plate inside the transom and in the splash well.

After the repair, the SeaCast does not absorb water so there is no worry of water intrusion to rot anything. The bolts and holes need 3m 5200 sealant.
