I went to put my boat (1999 prostar) in the water the other day when something happened.
I got it into the water, turned my power on and went to crank it; well in the middle of me starting the motor everything shut off, no power on the entire boat. I tripped the main breaker on the back of the engine and that wasnt it, i ruled out a bad ignition switch already, the battery is hot, all of the connections are tight and not corroded at all. The boat has a perko battery switch on it, im not sure if that has something to do with it, but can anyone offer me a little insight please. Thanks

Break out the volt meter and start making checks at the batt switch and move upstream from there.

Is every thing dead? Blower, lights? The exact thing happened to my Maristar a few weeks ago when I went to start it, it started to turn over and then every thing went dead. The problem was my battery connector. I clean my terminals every spring, but the positive terminal was on old brass connector and it had tarnish on the inside of the connector. The tarnish made for a bad connection which caused it to arc and burn when the starter kicked in. All my tools were under the rear deck, which I couldn't raise. I had to wait until someone drove by with a 1/2 inch wrench to remove the deck hinges. Replaced both battery connectors and haven't had a problem since. I now keep a 1/2 inch rachet in the glove box (just in case).
