I have an 86' 200 Osprey with the raised beveled top cap and I'm trying to decide on either a 60" or 72" shaft for a trolling motor. I'd like to go with 60" if possible but the distance from mounting surface to the waterline is right on the brink of Minn Kotas chart between 60" and 72". Looking to see if anyone has experience with trolling motor shaft length on this hull. Thanks.
