tigerinfielder3, what kind of boat are you wanting to put it on? I have one on a Ranger RT188, and previously had one on a Triton VT19. I think mine is 24V 80# thrust, more than enough power for the mentioned boats. I would recommend that you get the iPilot link and hook it up to a couple of Hummers. I can assure you it is one heck of a setup and worth every penny you spend on it. I bought my iPilot from shutupandfish on this site, good prices, fast shipping, and great to deal with.
