Transom Repair

I have a 82 cuddy and found this site last week. It is full of good info. My transom was starting to get soft around the port splashwell drain and while researching here I found a link to seacast transom repair, i liked the theory, and last suday I took a chainsaw to the transom of the boat :o. It went pretty easy and this sunday I am going back together with it. I am actually going to use west systems epoxy to fill the void because I have used the product for years on big and small projects and am familiar with it. I called seacast to get pro's and cons but they wern,t very helpful/knowledgeable. The guy I talked to at west systems told me the biggest problem would be heat as the epoxy cured, and told me a couple of ways to keep the temp down. I will get some pics up and and let you know how it goes.
