I have a 17' bowrider that I am having trouble deciding on how I can mount an electric motor to. I haven't bought a motor yet, but will be a Minn Kota. The problem is the bow isn't flat, but sloped. Any ideas? I would think that I somehow need to shim the mounting bracket. I have a picture of the bow, but don't know how to post it here. Thanks for your help.<br /><br />Brad
