Is there a fuse box on a Montauk? If there is, where is it located? My bow and stern lights are not working. I have searched for this answer with no luck. Thanks, Ric.

Boats sold by Boston Whaler are wired in accordance with Coast Guard and ABYC practices, so it is very likely that the original configuration of the navigation lamp wiring included over-current protection of some kind. Depending on what year the boat was made this could be either a fuse or a circuit breaker.

The wiring is very simple and in the most part completely open and visible. To locate the fuse just follow the wire from the navigation light switch back to the battery. You will find a current limited device in the circuit.

On older boats 3AG size fuses were used and located just above the switches. On newer boats the switch itself may be a circuit breaker. On the latest models there is a power distribution panel which contains a number of automotive style blade-type fuses. All of these are very obviously visible and are generally located for easy access and fuse replacement.

Boat electrical systems are often modified by dealers or owners, so there is no way to determine exactly what state your boat is currently in. It is very common for haywire modifications to have been made.

If you are at all familiar with electrical troubleshooting and circuit analysis, it is a very simple matter to verify if voltage is present at the navigation light switch and to trace the circuit to locate the fault. If you are not familiar with electrical trouble shooting and circuit analysis and do not have a voltmeter, it will be impossible to explain how to diagnose the problem. In such a situation I recommend getting a book on basic electricity and wiring. There are some very nice ones available specifically for marine applications.

I have done what you said and followed wires but did not find anything. I will look again, and then pic up a voltmeter and figure it out.

Thanks for the pointer/info.

PS it is a Feb. 1993 model, and I should have stated that.

My 1989 Newport (same hull as a Montauk) had a fuse in the small connection box mounted by the battery, where the wiring heads into the hull for the bow light. It looked factory to me, had a black base with the fuse holder on it and terminals, mine was corroded to just about nothing though. My boat I guess was a basic version, no gauges other then a trim gauge and one push pull switch for the lights, sort of neat running a boat with nothing to look at other then the broken trim gauge, no worries! Good luck...jack

The wiring under the console is subject to a lot of modification by owners, so perhaps something has been changed or removed.

It may also be that the switch itself is a circuit breaker. I am not familiar with the 1993 vintage. You can always call Boston Whaler Customer Service and they probably have a good handle on what sort of fuse or circuit breaker was originally there. It may be long gone by now, however.

The owner of the Montauk i just purchased knocked off $$ for a Raytheon fish finder that he couldn't get working. I had not seen it when i first tried the boat because he coulnd't find it.
First thing i checked when i got it home was the fuse panel in the console. At first glance the fuse looked good but from experience,, i pulled it out,, stuck in a new 2 amp and magic,, the fish finder works.

The bow light worked but the stern light did not...had to change the plastic bulb hoder w/ attached wiring...

all working now! Thanks to all for replies!!

sharkbait, if you stick your head under the console, you
will see that that circuit breaker is separate from the
switch. Close to it, but separate.
