Its actually very easy. Call Allen in parts. Get the large RAM with square base along with a 6″ access panel and all hardware. All you need is a 4.5″ hole saw along with #2 square bit for the BCB screws. 1. Remove trollingmotor pedal.2. center up your access panel.3. cut the whole in the center. ( once your panel is centered under your pedal, park the 4 wholes in the panel then take a ruler and cross the dots, this will give you a center spot to cut your hole)4. decide where you want the RAM base then drill your bolt holes. 5. Bolt down base, screw down access panel, replace trolingmotor panel. (when putting the fender washers under the deck, put a dab of silicone on the washers, This will hold them so you can put the lock nut on)
