We are going to start building the motor mount for the tri-hull. When we tore it apart there was basically nothing left of the old one.

We took measurements of the bilge so we know where to put it but I had wanted to lay grade 8 studs into the motor mount so there would be zero water penetration into the wood.

The only way I see of doing this is to get the transom completed (final layers of glass, its already in the boat) Then put the transom plate back on the back wall and then place the motor on the rear engine mounts and mark where the studs have to be.

My question is, am I over engineering this thing? Do the front motor mount holes need to be able to be adjusted from left to right for alignment? Or for anything else for that matter? Anyone see a flaw in this design? I only ask because like I said there was basically just a piece of fiberglass holding the front of the motor up.
