Well I did my homework and it panned out. I have a plain power drive and bought a power drive V2 control board and the instructions said I would have to drill out a pressed in brass piece but the new version of the replacement part has a spot made in it that fits right over it so I didn't have to drill anything. put the parts in and followed the IPilot instructions and Bingo it works! haven't put it on the water to check track mode but checked left,right motor on, speed up,speed down, and auto pilot and all of it worked great! Now I need to get it on the water after reading book. Thanks for all the help you guys give. I ended up with a Ipilot troling motor for about half the price a new power drive with a IPilot installed.
