Installation Instructions:
1. Remove both side covers (marked [A] in the illustration).
2. Position the Lock Pin [4]. The Handle Assembly [3] can be inserted from either
side of the motor once assembled. Install the Lock Pin on the same side that the
handle will be used. The Lock Pin will be retained by one of the screws securing
the motor to the Outer Plate.
3. Use the (6) 1/4" x 1 1/2" Flat Head Screws, (6) 1/4" Washers and (6) Lock Nuts
to fasten the Outer Plate [2] to the bottom of the motor base extrusion oriented
as shown.
4. Re-install both side covers. Position Outer Plate [2] over Inner Plate [1] and
secure with the Handle Assembly [3].
Note: Mounting template is located on the inside of the box. Cut template out and use it in step 6 to mark and drill the mounting holes for the Inner
Plate.
5. Positioning the motor/quick release bracket for mounting location:
A: For PowerDrive or Terrova motors fully deploy the motor and position the bracket/motor on
the bow of your boat to check for proper clearance (the motor, as it is lowered into the water or
raised into the boat must not encounter any obstructions.)
B: For Ulterra Motors postion the bracket/motor so the notch in the base is aligned with the
rubrail of the boat (for proper clearance the entire notch must be visible beyond the rubrail, as
shown to the right.)
6. Mark the side edges and rear of the quick release bracket on the bow of your boat. Set the mo-
tor aside. Position the template on the marks. Locate the four mounting holes in the template
and drill the holes to a 17/64" diameter. Fasten the Inner Plate to the bow of the boat using the
(4) 1/4"-20 x 3" Flat Head Screws, (4) Fender Washers, and (4) Nuts.
Note: Due to variations in boat mounting surfaces shims under the Inner Plate may be required.
If the Inner Plate is not mounted flat the Handle Assembly will not slide in easily or properly. After completing installation if the Handle Assembly does
not slide easily into place it may be necessary to ream/drill out the handle rod holes. With inner and outer plates assembled use a letter "F" (.257") drill
bit to ream the rod holes so that the Handle Assembly slides easily into place.
7. Mount the trolling motor/Outer Plate onto the Inner Plate, slide the Handle Assembly into place and secure with the Hair Clip Pin [5].
8. Your motor is now mounted. Always make sure the handle assembly is fully inserted and retained by the Hair Clip Pin.
Note: You can use a padlock in place of the Hair Clip Pin to prevent motor theft.
