I want to mount my trolling motor onto my 2007 Four Winns Horizon with a quick release bracket. I have a Minn Kota Riptide SP. The only quick release mounts I can find online are these. Problem is, the area on my bow where I can install the bracket isn't level. The part of the quick release mount that gets installed onto my bow looks pretty small. Anybody know if I can get away with leveling the small part that gets installed onto the bow or if I should make some kind of small level platform out of star board or something and install the bracket onto it? Alternatively, does anybody know if there is a quick release bracket with a larger bottom piece that I can use with this motor?
