Coach, my neighbor has a 15 ft express with pod seating and a 25/ 2 stroke Merc. That thing has caught bunches of crappie pulling cranks. 5 gal bucket if needed. Mount you a base on opisit pod for your drift masters and cut down a piece of 1/2 in all thread from home depot. Mount your crossbar on that. Make about 6-9 inches high. Poles you have will work just fine. Your motor should have a steering adjustment screw on it where you can tighten up the steering. If need be get you a brass or stainless ring that will fit over your tiller. Attach a couple of stout bungies to it and adjust them where they have enough tension to help hold it straight. Mount that to sides of boat. When needed just grab ring and slip it over the handle.
