The only thing I would be using silicon for on my boat would be to seal the cupholders!

Permatex RTV has its place inside the engine (intake manifold gaskets, etc), but not on the hull.

Seriously, below the waterline? Thats just a bad idea. You get a leak there and your boat can sink. A marine sealant meant for underwater gear would be the proper thing to use.
