Let the boat burn baby, burn!!! Boat catches on fire, I am not going to get in its way. That is why we have replacement cost insurance. Game warden once commented on time to replace the unit because the gauge was showing a little low. I flat out told him its only in the boat because it has to be. Boat catches fire, its going to burn and sink to the bottom. He didnt like that answer. Reality, its a great thing.
