I appreciate the "learn your boat" idea. I'm currently using a buddies boat. It ran like crap, I took it to the shop. Runs like a raped ape now. That said, I know where the batteries are and can disconnect them, but I don't have a clue about the engine cover or fuel disconnect. Will fix that lack of knowledge the next time I walk up to the boat. I do know where the fire ex. is, but it may be as old as the boat. Will check that also.
The best way to get to where you want to be in the future is to act like you are there TODAY.
