I am replacing my transom on my 16' Starcraft Supersport (1970). The transom is basically a bolt in, so I made a new one, got it all sealed up, and am installing it as we speak. I'm sealing all the bolts with 5200 (debated between boat life and 5200). My question is this. I'm putting on a different engine than was on before... Was 1970 Johnson 85, looking like going to newer Suzuki 70. Should I redrill the existing engine bolt holes or not? Should I just fill up the aluminum part of the hole (wood is solid now) with 5200 and then put the back piece of wood on? (it's the wood on the very back of the boat, don't know what it's called)
