There are two primary circuits on your boat. One strictly for the engine and gauges. The other feeds the lights and other accessories. The fuse or circuit breaker for the accessory (boat) circuit will be located in the positive lead within one foot of the battery. The engine circuit fuse is under the engine cowl. But since you didn't tell us what engine you have we can't help with that.
