The MKA-58 Reinforcement Plate has an assortment of threaded
and recessed mounting holes. Each style of mounting hole serves a
different purpose for installing the Plate. Become familiar with the
application of each style of mounting hole:
1. The recessed mounting holes are for installing the Reinforcement
Plate to the boat deck.
2. The six threaded holes around the outside perimeter of the
Reinforcement Plate are for installing the trolling motor base
extrusion directly to the Reinforcement Plate.
3. The twelve threaded holes around the inside of the
Reinforcement Plate are for installing the Inner Plate of an
MKA-56/RTA-55 Quick Release Bracket.

When checking motor clearance for a mounting location, please give
consideration to the following:
1. The MKA-58 is compatible with freshwater and saltwater
electric-steer, bow-mount, QUEST series trolling motors,
including the Ulterra QUEST, Riptide Instinct QUEST, Terrova
QUEST, and Riptide Terrova QUEST. The base extrusion of the
trolling motors may vary. Please note the appearance of the base
extrusion for each trolling motor.
2. It is recommended that the motor be mounted as close to the
centerline or keel of the boat as possible. Installation of the
Reinforcement Plate requires the use of all six mounting bolts.
Mounting bolts spaced furthest apart will create the most stability.
Ensure that the mounting location is flat and that the area under
the mounting location is clear to drill holes and secure hardware.
3. The motor must not encounter any obstructions as it is lowered
into the water or raised into the boat when stowed and deployed.
In the stowed position, place the motor so that the slot in the
Base Extrusion is positioned beyond the boat Gunwale. For
proper clearance, the entire slot must be visible beyond the
Gunwale. When the motor is deployed, there must be a minimum
required distance of 1½" between the Gunwale and the bottom of
the Steering Housing and Shaft.
4. With the motor in the stowed position, ensure there is enough
room for the Shaft and Control Head and that they do not extend
off the side of the boat.
