f.  Measure the proper length of the Aluminum Rod 

by standing it, with the threaded end down, onto 
the deck surface so that it sits vertically right next 
to the Stabilizer Bracket.

g.  Mark the Aluminum Rod with a pencil or marker 

3/4" past the top of the Stabilizer Bracket. 
 
 
 
 
 
 
 

h.  Cut the Aluminum Rod with a Hack Saw at the

j.  Thread the Aluminum Rod into the Stabilizer 

Bracket with the Bottom Bumper towards the 
boat deck. 

k.  Adjust the Aluminum Rod up or down in the 

Stabilizer Bracket so that the Bottom Bumper 
just touches the support surface. The Aluminum 
Rod should have the ability to lift off the boat 
deck about 1/4” without the mount unlatching.

CAUTION

Cutting the Aluminum Rod too short will cause 
inadequate support of the mount. Lack of mount support 
may cause damage. 

CAUTION

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.
