This boat has a small surface crack on the inside part of the transom, on the hull wall opposite of where a 6 HP outboard is mounted and exerts force.
These images make the crack seem large or like it's pulling away from the wall, but that's just an effect of the flash and image angle. It's been ran the past 3 seasons with the crack and no resultant leaks. I'm conducting this 'fix' for peace of mind.
The boat manufacturer recommends a 2-6 HP engine, but there was formerly a 10 HP outboard mounted, which caused this crack. On the outside, the hull and jackplate mounting in this area are 100%.
My thoughts were to marine epoxy the crack, and make a wooden or metal brace that should help distribute the force over a larger surface area. This brace could be fiberglassed in too, but I want to be able to remove it should I need to service this area in the future.
Structural reinforcement is most important spec here. You can ignore the wires as they'll be rerouted soon. This fix may see the occasional splash of gasoline or water.
What do the resident experts of CR4 recommend? I can supply more info/pics as requested.
