ITEM(S) NEEDED
#2 x 6
NOTICE:
The mounting surface for the Bottom Plate
must be completely flat. Washers must be used to shim
the Bottom Plate flat before hardware is tightened.
The Top Plate will not fit correctly unless the Bottom
Plate is installed completely flat. To prevent seizing of
the stainless steel hardware, do not use high speed
installation tools. Wetting the screws or applying an
anti-seize may help prevent seizing.
h. Put a 1/4-20 X 2" Flat Head Screw (Item #2) in
each of the six drilled locations. The bolt should
pass through the Bottom Plate and the boat deck.
Make sure to secure the motor with bolts on each
side of the Bottom Plate.
i. Place a Flat Washer (Item #8) and then a Nylock
Nut (Item #6) at the end of each bolt as shown and
tighten with the 7/16" Box End Wrench. Make sure
all hardware is secure.
