I have a Mercruiser 5.0L MPI Bravo 3. This past Saturday, I killed my batteries while playing music all day. I got a jump and got the boat started. I noticed when I took off that the boat seemed to lack the normal power. About half way back to my destination, I noticed that the battery gauge was acting erratically (going up to 16V and then back down to 12/13V). As soon I got near to dock to pull the boat onto the trailer, the boat shutoff. I then had no power to ignition or dash switches. Any ideas? Should the 50A circuit breaker be all the way in or out?
