a.  With the Top Plate secured to the motor, reassemble 

the Quick Release Bracket. To reassemble the  
MKA-51, set the Top Plate and motor onto the 
Bottom Plate (Assembly #B), leaving a 1½" sideways 
gap between the Plates. Slide the Top Plate and 
motor sideways to close the gap and realign the 
Plates. Secure the Plates together by closing the 
Cam Lever and inserting the Pin.

b.  Place the motor with the MKA-51 attached as close 

to the centerline or keel of the boat as possible. The 
motor can be installed on either the Port or Starboard 
side of the boat based on personal preference. 
Review the Mounting Considerations at the beginning 
of this document to ensure proper clearances.

NOTICE:

 Make sure that the motor will not encounter 

any obstructions when sliding the motor on and off the 
Quick Release Bracket. The exact placement of the 
motor when mounting may vary depending on the boat, 
boat deck, and base extrusion or bracket the MKA-51 is 
being mounted to. The Ulterra motor cannot be deployed 
before mounting and connecting a power source. 

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.

c.  When checking clearance, make sure to check for 

obstructions around the MKA-51 and motor when 
they are in all possible positions. The Top Plate 
moves sideways approximately 1½" and also slides 
inboard 6". This allows the motor to be moved for 
trailering, transport, or a boat cover without being 
removed. With this movement in mind, make sure 
to check for additional obstructions, such as a 
windshield or lights.
