Hello, my name is***** will assist you.

What you have is either a shorting stator, or there is a short to ground in the boat. this can be as simple as a wire connected incorrectly, or even a failing battery. If you are trying to charge more than one battery with the engine, that can also do it, as this engine was not designed to run several batteries.
