Depends on what you have. I assume its a transom mount motor? What does your transom or the back of your boat look like? <br />I have a '72 fiberglass trihull and the rear is 2 ft wide with the gas tank and battery stowed underneath.<br />The transom mount motor clamps on to the transom (which is about 3" - 4" wide) but on mine it is encased with 2 ft of a fiberglass shelve so to speak. There are brackets that you can mount to the outside of the transom that you clamp the motor to. Heres one to give you an idea.<br /><br /> http://www.iboats.com/mall/index.cg...ransom mount trolling motor&cart_id=064708297 <br /><br />Bob
