Narrowing down to trolling motor options for the new boat. Going with a MinKota Ultrex. My boat is a 1860 Alweld Center Console with a 115 Yamaha. Would you go 36volt or 24volt. I want to save weight as much as possible has me leaning towards 24 volt but I don't want to buy the 24 volt and regret not buying the 36. No real money difference in price.
