TROLLING MOTOR INSTALLATION AND OPERATION
IMPORTANT: A minimum of four mounting bolts are required to mount the
trolling motor to the boat. Spread the mounting bolts as far apart as practical
for the most secure mounting.

3. Drill the mounting holes with a 7 mm (1/4 in.) diameter drill bit. Remove
any debris.
IMPORTANT: Using a larger drill bit, countersink the holes on fiberglass boats
to prevent cracking.
4. Insert the rubber isolators between the base of the mount and the boat
mounting surface. Place the tie‑down strap under the mount bracket,
hook‑and‑loop side down, with the buckle facing toward the outside of the
boat.
NOTE: If the trolling motor is being mounted to a carpeted boat deck, the
rubber isolators are not required.
