what would make the breaker pop off while running ? I have checked the engine with a remote starter box . Runs great on it . I have looked in electric panel down stairs . It runs for a while like nothings going on then shuts off at breaker . I put new on in and looked behind dash at switches
Perhaps there is a short on one of the wires, or a component that's shorted. Your best bet is to get a marine electrician out. Or start ohming every wire connection on the entire circuit.
