Depending on the year of your boat you probably have Eaton Heinemann type AM1 magnetic-trip circuit breakers that act as starter circuit switches (15 or 20Amps). AM1 single pole breaker's physical size is 3/4in wide x 2 7/16 long with two studs on rear for electrical connection. The stud size is also standard and I think it has 10-32 threads. The breaker is designed for panel mounting and mounts in a 3/4 x 1 7/16in rectangular hole. Airpax manufactures an identical breaker designated UPL1. Carlile and some others also manufacture the breaker but I don't remember the type.
They can be purchased from an electronics supply house as a Heinemann type AM1 BREAKER OR EQUAL. You need to know the trip amperage. The amperage trip-time curve is not critical for this use. Breaker size can be found on either the trip handle or on the side of the breaker.
Good luck!

They should be available from Defender. There are 2 common physical sizes (A and C), check the specs and measure what you have.
