Trolling Motor Circuit Breakers - 60amp

[Tin Man]

During my wiring planning I recall reading that ABYC requires circuit breakers to be mounted within 7" of the source of power (battery).

My new boat came with a 12V TM and I am changing it out to a 24V TM. The OEM wiring for the 12V TM did have a breaker with a short 7" pigtail to positive side of battery. The breaker was not mounted, just free floating on wire circuit. Apparently they followed ABYC guidelines...good to know! However, I wonder if mounting the breaker is also an ABYC requirement?

The 60amp breakers, typically used on TMs, have two mounting holes for use when mounting the breaker to a flat surface.
How could this breaker be mounted to flat surface (ex. battery compartment) and still be within 7" of the positive battery terminal?

Are your breakers within 7" and how did you mount the breaker so close to battery to accomplish this? Pics would be appreciated!

Thanks!

Pic of breaker in question.....

I can take a pic of mine tomorrow but the 3 trolling motor batteries are in the center console with a charger and fuse panel and circuit breakers mounted vertically to a piece of plastic board.

On the G3, it is close to the battery, but not mounted to anything. On the DMI 1648, mounted to the plastic battery box.

My Crestliner 1750 has the breaker within 2ft of the house battery. The TM breaker is within a foot or so.

It may or may not be ABYC compliant but, a guy could add fuse that is somewhat larger than the breaker directly at the battery post. Then mount the breaker nearby. The wire from the fuse to breaker would need to be large enough to handle the fuse breaking current.

My breakers are close to the batteries, but the wires to the batteries are longer than 7".

Here's mow I mounted my breakers relative to the battery. The breakers (one for TM, other for accessories fuse panel) are mounted on the side of the center bench.



OBTW: Any adherence on my part to recommended 7" distance to the battery is pure accidental.

Mine is about 6" from the positive post of the battery and free floats with the wire. It's inside the box when the lid is on the box.

I'd say I'm within 7" of the pos terminal, mounted on the inside wall of the center battery compartment before the lead wire goes 7' forward to the trolling motor.

I used 6 gauge Ancor wire from battery to 60 amp breaker to trolling motor.

That's my precise plan! Thanks for pics. Breaker install looks great!

Mine is easily within 7", but mounted on the other side of a bulkhead. So the cable run is at least 16" if I had to guess. I think I used the same breaker as you.

Mine is inline on the wire, like Ray's.

Better to never use it that not have it when you need it.

Thanks for the replies and pics. I'll try and get the breaker distance from pos battery terminal as close as possible to the 7". I will mount it to the battery compartment.
