Repowering V20- looking for some input

[Bosts1]

So are you saying if nuts go outside the transom you can take off motor and move and not completely reseal everything? Seems risky. I believe mine now is bolted on nuts against the motor. I will be putting a motor plate on top bolts and checking the transom good while its off. I have never drilled in it and found wet though. Always good light dusty shavings on the bits!
