I have no choice but to replace the transom, upon acceleration from the 150 Johnson, you can see the transom flexing and twisting. Someone drilled a hole underneath the drain plug about 3/4 inch and water seeps from the hole continuously leaving a dark brown or black buildup on the outside jel coat. Almost every time I take the boat out I have to tighten the mounting bolts, I have slowed this process down by installing a 1/4 stainless steel plate under the nuts and washers inside, I know this is a temporary fix and almost completely stopped using the boat. I have dug up in the hole with a scribe and removed rotten wood and also some floatation foam. The smell of this stuff is terrible.
Any help with this project would be appreciated, as I have never tried to do anything like this before. I am a retired Auto body man and painter (never worked with corvettes) and if the boat were made out of metal I would know what to do with it.
I am planning to start and finish he project during the winter months in my shop in the back yard when things are slow. I have all of my body shop tools and I cant think of anything else I might need.
I am going to make some minor changes to the transom rebuild to allow for installation of a kicker motor (35 Hp Evenrude) and will be refinishing the boat completely.
