Well it’s been a busy summer to say the least. Work is at a stand still on the boat due to fishing but that’s good, I’ll be able to make some money to throw at the thing.

How many tapes? Load path is to move the transom top forward, so offsetting that is key.

Work looks good. I'd want minimum 3 tapes there, maybe 4, depends on hp.

Horsepower is a 115 four stroke Yamaha. I just taped one layer of 12oz. Biax as it was my first bit of taping and wanted to see how it turned out. Had to fillet around a few spots too so that took some time.

How many layers of 1708 biax I should use to build up the transom? 3 staggered layers? Was gonna try and cut the longest layer the full length of the well to the stern of the boat.

If it were me I would want a couple of layers of 1708 or 17oz biax running across the face and back along the well to the stern. That would give lots of contact area for the new glass to band to. The plywood looks thick enough that you should not need a lot of glass on it to make it plenty strong. Maybe add 3-4 layers of tape to the joints but that might well be overkill.

Not overkill at all. Minimums. This boat transom is sort of a transom in reverse. Consider no tabbing. Revving the engine throws the plywood forward and it falls into the boat. A conventional transom pushes the boat forward until it goes in reverse.

All about load path; this transom needs lots of reinforcement so that overtime it does not stress crack on the top edge, or worse.

Heat index over 100 next couple of days. Definitely not epoxy/boat building friendly
