I'm about to start the transom project. I wanna bounce my plan off of you guys to make sure I'm not doing something silly.
First off, I'm going from the outside because I perceive it to be easier than cutting through all of the boxes and such on the inside and I'm hesitant to pull off the cap for fear of opening a can of worms that needs to stay shut for a few more seasons.
Phase 1:
-Cut about 3 inches (1/4" skin at 1:12 scarf sound right?) from the outer perimeter of the transom.
-Remove rotten wood, prep inner glass surface for bonding.
-Measure and decide what thickness foam to order.
-Trim Coosa Bluewater 26 foam to fit.
-Drill holes to allow for air to escape and insertion of lag bolts to squeeze it all together.
-US Composites Thin, Slow 635 Resin thickened to mayo consistency and slathered on Coosa and inner skin.
-Bolt together and let it setup.
Phase 2
-Prep outer skin and Coosa surface and coat with thickened epoxy as before.
-Use long, stiff boards to ensure outer skin is flush with the remainder of the transom and bolt it all together, remove squirted out epoxy and let it set.
Phase 3
-Prep skin scarf for VINYL ESTER fiberglass repair, build up per standard procedure and let set.
-Sand/fill/fair with color matched gelcoat. (I think I need to use a wax free ester for the last glass layup to allow for the gelcoat to stick?)
Phase 4
-Overdrill holes/fill/redrill for engine mounts, scuppers, etc. (maybe do predrill ahead of time to make things easier?)
Phase 5
-Catch fish.
Thoughts and advice much appreciated.
