[QUOTE="MrGiggles, post: 507526, member: 22613"] What they say regarding the motor being oversized is true, but only in terms of spot lock performance. They are roughly calibrated to ramp up speed in accordance with boat size, if the motor is undersized, the boat may drift off the waypoint before the motor is ramped up fully and brought back, if oversized, it may ramp up too quickly and overshoot. The higher end Minn kotas have a setting for this (called boat scale as I recall), however it is not available on the Terrova if I remember correctly. 24V motors are quite a bit more efficient, resistance losses are halved. Even with two identical batteries, the 24V will go further than the 12V. If you do any electric trolling, fish in heavy current, or on big wind-swept lakes, 24V is the way to go. If you're only fishing small bodies of water, trolling with the outboard, or anchoring a lot, a 12V motor will do just fine. I have had both on my boat, I prefer the 24V as I do a lot of crankbait/bottom bouncer trolling, I used a 40lb thrust Powerdrive for quite a while and found it to be more than adequate, it was just a little bit hard on batteries while trolling crankbaits, and I wanted Ipilot so I upgraded to the 24V Terrova.
