What type of boat and Motor. What size trolling Motor?
Optima's are about the best $ can buy but are very expensive and a dead one will not start your motor any better than a dead one from K-mart.
I have an I/O. I would never consider using my motor starting battery for anything except starting the motor and running the depth sounder. I would hate to run the battery down with the trolling motor and not be able to start the boat motor for the ride home.
If I was in a smaller boat with a motor that had a pull start I would not be as worried.
What I did was to buy a COSTCO battery, the biggest one that they have for a starter battery and the biggest deep cycle they had for my trolling motor. Together the cost was about the same as the optima would have been alone.
This set-up also works best when another boat needs a jump I just pick up the trolling motor battery and use it for the jump rather than risking anything on my boat.
