i dont think they make that high of thrust trolling motor for 12 volts, but i could be wrong. i have a 70 pound thrust motorguide trolling motor on a basstracker 185 aluminum. plenty of trust for the river but on high speed it wants to torque the foot petal, if its not pointing straight ahead. i have had an optima starting battery for years, and in my opinion theres not a better battery for a starting battery. ive not had any experiance with the optima trolling batteries. ive got a 90 hp mercury, and the starting battery is 10 years old. sits out in the cold, i dont have a garage. my friend has a 200 hp optimax , and he got 8 years out of his optima starting battery. his was out in the cold too
