Hey guys. I have a 35 HP Evinrude on a 15ft Alumacraft. I'm trying to eliminate some of the weight at the back of the boat. I currently have large deep cycle battery for the trolling motor and a large dual purposee for cranking. I was wondering if I could get by with a small lawn mower battery for cranking. It starts easily and I can always pull start it if I have to. If so, would it be OK to charge it with my onboard 2 bank battery charger?
