Will this work in my boat

I would say no, you have no cooling system to put this into because boats pump live water through the engine to keep them cool

I have a cadillac 4.6 northstar. should i use two bottles on it, or can i get away with one?

Your cadi is a v8.. therefore use 2. But please call them for special instructions pertaining to that motor.. you have to find which cylinder is leaking first and remove that spark plug, then run it up to temp with the spark plug out! Let it cool over night and run it up to temp a second and third time to heat cycle it. THEN put the spark plug back in.

how do i use steel seal>

follow the instructions closely.
