I bought a MK Terrova 36v 101# w/ auto pilot. I fish a 23' centerconsole. The aspect of this motor that has REALLY caught me off guard was how long the batteries will last with this motor. We fish from dark to dark on cumberland for striper. Been pulling planers all day for the last 2 months and have yet to see the batteries below 1/2 charge. I was flat out amazed.
