Add a deep discharge for trolling.

Depending on your charging circuitry, you will either be able to do 2 at
once or you will need to buy a dual charger for the Yamaha.

What you want, is the ability to "isolate" the 2nd battery for the trolling
motor so you always have a fully charged main battery for starting.

You were all such great help when I built my kayak and canoe, I thought
someone might be able to help me on this. I bought a small 16 foot boat
last month with a 60 4 stroke Yamaha and wanted to install a 12 volt
trolling motor for fishing. My question is, should I install a seperate
deep cell battery for the trolling motor and charge it when I'm done
fishing, or replace the battery that's on the boat with two deep cells. I
figured the motor would recharge the batteries but I wasn't sure if they
could handle starting the motor, running the trolling motor, bilge,
lights,
and my son's Game Boy. And would the motor be able to recharge both
batteries. Any suggestions or opinions?
