makes sense. thanks. This is off topic for this thread but how many sheets of ply did you use for your transom?

2 sheets of 3/4" marine grade ply, birch. You just can't get two transom cut-outs out of 1 sheet. Very close but not quite possible.

So your ply in your transom is 1.5"? I was way overkill thinking 4 sheets. for 3 inches of ply.

2 sheets is fine, that is what the factory originally installed.

Sweet. You think I should use 3 since I'm going with a bracket? Or the knees would be fine?

[tartuffe]

I don't have any experience with brackets and don't know how they distribute force on the transom.

Original transom has two layers. Whoever rebuilt the transom in the 18 Fisherman i have used three layers of plywood. The transom is rock solid.

CTerrebonne why not use one piece stringers that extend out the transom and build a bracket off them? That is what i am trying to figure out how to do now. Then you have no load on the transom unless you want it to be loaded. I plan on one layer of 3/4 ply in my transom. Just an idea,.

On a side note, one of the major bracket manufacturers says in their online installation instructions, if the transom has soft spots or rot to add one piece of 3/4 ply to the inside of the transom.
