Compatible with Minn Kota® Freshwater Electric-Steer Trolling Motor models, including the Ulterra™, Terrova®, PowerDrive™, PowerDrive V2 and DeckHand 40.
MOUNTING CONSIDERATIONS
It is recommended that the motor be mounted as close to the
centerline or keel of the boat as possible. The motor must not
encounter any obstructions as it is lowered into the water or raised
into the boat when stowed and deployed. Make sure the motor rest
is positioned far enough beyond the edge of the boat. Make sure the
area under the mounting location is flat, clear to drill holes and install
nuts and washers.
p Not shown on parts diagram.
NOTICE: The mounting surface for the Bottom Plate must
be completely flat. Rubber Washers can 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.
