Bow Mount -> Battery Cable Extension

Recommended Posts

On larger bass boats, I believe all of the batteries are stored in the back compartment. This includes the ones for the bow mount trolling motor. I currently have a 55lb Minn Kota Powerdrive V2. The cable is only about 4' long. The part that connects to the actual battery is a small circle (this is what it looks like: 0717151538b2.jpg 

 

I can't figure out how it is supposed to attach to the actual battery. I am trying to figure that out, as well as extend the cord so that i can keep the batteries at the back of the boat and balance the weight out better.

 

any info/help would be great. Thanks again!

Snip the ring terminal off that end and get some 6g or 4g MARINE wire depending on the length of the run. Run the new wire to the back of the boat up to the TM. Solder and heat shrink the connections between the TM power cord and the wire extension . 12v systems need larger wire than 24v systems.  You will need a 60a breaker near the battery on the hot wire for the trolling motor. 

 

Here's the chart for reference as to what breaker and gauge wire to use for your motor:

Bow mount trolling motors are seldom hard wired all the way to the battery. Normally, the motor wires are connected to a plug, and the receptacle is hard wired back to the battery.

Unless you re wired your bass boat it should already have the proper wire and circuit breakers from the battery compartment to the bow receptacle.

Enough of this to go from front to battery circuit breaker in back and to make jumper from breaker to battery (if you get the Minn Kota breaker)

 

Enough of these to go on cables https://www.delcity.net/store/Straight-Copper-Lugs/p_810730.h_810732.r_IF1003?mkwid=sVCgbMf4M&crid=38094426869&mp_kw=&mp_mt=&gclid=EAIaIQobChMI-Kesqsnq2wIVRRuBCh0g0QA8EAQYASABEgI13PD_BwE .  Crimp and solder these.  Use Benzomatic torch and rosin core solder to solder

 

These items are available at many places, I just used these for reference.

 

 

the link to the 6 AWG fine wire battery/marine cable didn't show
