MOUNTING CONSIDERATIONS
TOOLS AND RESOURCES REQUIRED
The Bow-Mount Stabilizer Kit is used to stabilize the
Bowguard/Steering Module and reduce bouncing when
the motor is stowed and transported. Attention to detail
is needed for successful installation. Before mounting
the Bow-Mount Stabilizer Kit, give consideration to
the following:
a. We recommend to have the MKA-50 Stabilizer Kit
installed by a qualified marine installer.
b. The MKA-50 Stabilizer Kit is intended for use on
either the Fortrex or Ultrex motor. The Stabilizer
Bracket mounts to the Bowguard on the Fortrex
and the Steering Module on the Ultrex.
c. Installation on Fortrex or Riptide SF is slightly
different than installation on Ultrex, be sure to
follow instructions appropriate to your motor.

NOTE: The MKA-50 Stabilizer Kit can be installed on
the left or right side of the Bowguard/Steering Module.
When mounting the kit onto the Ultrex, the two Nylock
Nuts (Item #12) are discarded because the bolts are
secured directly into the Steering Module.
The two
Lock Washers (Item #16) are not used when installing
on the Fortrex.
UTION
Adjusting the Aluminum Rod too tightly removes the end
play needed for proper latch pin engagement and doing
so could prevent the mount from fully latching in the
stowed position. Improper latching may cause damage.
If installed correctly, the tip of the Aluminum Rod should
lift off of the boat deck about 1/4” without the mount
unlatching. Cutting the Aluminum Rod too short will
cause inadequate support of the mount. Lack of mount
support may cause damage.
