If you mount to the outside, say port....you will have to oversteer somewhat to compensate for the uneven push of the motor. Additionally, you'll have somewhat sluggish response when turning port. Starboard will be a dream though. Best to mount as close to centerline as possible for the best steering control and tracking. That said, the difference between 12 and 14" off centerline will be negligible. The difference between 12 and 24 would be significant though. Just get as close as possible with say 1" of safety space. Don't forget the transom will have some give and the motor will rock when on the trailer, hencse the cushion.

Ask Creek to measure how far out his kicker is off the center line. Bet his is significant, but bet he doesn't have any steering issue - 'course, he'll have more keel than you though for tracking. That's why I'm saying as close to center as reasonable.
