Re: Kicker mount on bowrider
My 2 cents:
A 54lb electric is barely enough for my 15ft trihull. 40lb would be poor for your 17ft boat.
My transom has the same issue, only flat maybe 1-1/2 foot to either side of the outboard. I also have (homemade) tabs. I solved all that by making a long-armed, fixed but removable, troller mount out of Starboard that mounts to the flat of the transom to the left side of the outboard, but the vertical plate that the electric motor hooks to is offset to the left so that the troller has room to turn (360 degrees) without hitting the OB, even with the OB turned all the way toward the troller. And the OB can turn all the way to the side and just clear the bracket.
Granted you are talking about a much heavier kicker motor, but if you could get something like that fabbed from some sturdy aluminum or stainless plate it could work. Maybe a squared-off "u-shape" turned on it's side, with one arm of the u longer than the other...
Not pretty, but could work and should be fairly cheap compared to a retail kicker bracket.
