Trolling motor / battery ??

[FTB530]

I want to mount a trolling motor on the front of a 14 foot aluminum boat I have a 15 horse electric start motor that charges the battery, i need information if I can run wires to the front of the boat and connect to the second battery,will the motor charge both batteries sufficient or what is another solution?

Sorry, that isn't going to work.
The output of your motor's alternator is very small. Barely enough to replace the current used to start the motor.
It would take hours and hours of running the motor, to charge the trolling motor battery.

Best bet is to charge the battery with a shore powered battery charger.
Even on a regular battery charger, it will take 3 to 12 hours to recharge the battery if it is 50% depleated.

Yep, the best you could do is extend your run time for the trolling motor by a few minutes. Considering what the equipment would cost to accomplish this modest result (ACR, wiring, and connectors), it would make a lot more sense to buy a larger and/or additional battery for the TM.
