i. Make sure the slot on the underside of the Base
Extrusion is aligned with the outermost part of
the gunwale of the boat. This will ensure that the
Shaft has a minimum clearance of 1-1/2" when
it is deployed. The lower unit, when stowed and
deployed, must not encounter any obstructions.
j. Check to be sure that the Motor Mount is level. Use
the Rubber Washers (Item #8) provided to create a
level surface, if necessary.
k. With an Awl or similar tool, mark all six mounting
holes in the Base Extrusion.
l. Make sure the area under the mounting location is
clear to drill holes and install nuts and washers. Drill
through the marked holes using a 9/32" Drill Bit.

NOTICE: Failure to allow 1-1/2" of clearance for the Shaft
when mounting may cause failures when the motor stows
and deploys. Follow recommended mounting considerations
to avoid obstructions when operating the motor.
