I added iPilot to my Powerdrive this spring thus losing my foot pedal. Worked great, the ipilot is a game changer with spotlock, following tracks, contours if you have Humminbird electronics. The only thing I didn't like about losing my pedal was the ability to stop the motor while fighting a fish without taking a hand off the reel. Hook a fish and it starts coming right at you, sometimes with the boat momentum and the fishes run towards you, there is a lot of slack in your line no matter how fast you can reel. With the foot pedal it was easy, bump with your toe and done, with the remote, take one hand off the reel, hit spotlock or the prop button, put hand back on the reel, fish gone! Thats my only negative about foot pedal vs remote. You do gain extra floor space on the casting deck without the pedal which on a 1650 would be nice (it is on my 1700)
All that said I used the the 55# Powerdrive ipilot all season and sold it this fall and bought myself a 80# Terrova, the extra thrust will do my boat well and will gain a more advanced pedal as well as remote.
