Carl, both are great motors. The Terrova is more expensive than the V2. I-Pilot seems to be a good choice with more options than Auto Pilot. The only draw back I have found with the I-Pilot is that it is a little slow to respond if you are trolling into the wind and the winds picks up. I guess it's according to how much money you want to spend. Your boat would do fine with a 55# thrust motor, but you would like the 24 Volt 70# thrust better, but that's the expense of a 2nd battery. The least expensive way to get what you want would be to go with a 55# thrust V2 PowerDrive with Auto Pilot. Doesn't cost much more to buy one with I-Pilot. The Terrova will be the most expensive between the 2, but you'll love either one.
