IMPORTANT - Final Adjustments and Locking
The last step is to center the tower on the boat and lock everything securely into place
to ensure the tower is stiff and silent.
IMPORTANT -
Center the Tower on the boat as
shown on here. Do this by measuring from the base on one side to the rear swivel on
the other side as shown below. Check both sides until the measurements are within ¼”
in both directions and then tighten the setscrews in the Part 9 Rear Swivel Collar and
tighten all M12 bolts in the top section to 65 ft-lbs.
The next step is to install Item 15 to lock together the Rear Top Section Swivel and
Rear Leg Swivel. This maximizes the side-to-side (lateral) stiffness of the tower.
Double
check that the tower is centered as above before drilling. Once holes have been drilled,
there is no adjusting the tower.
Use the included 5/16” (8mm) bit to drill through the pilot
hole and all the way through the other side of the mating swivel. Use a vacuum to
remove any metal shavings during drilling and wear safety glasses.
Drilling the mating swivels will be faster using the following steps:
1) Begin with the 8mm drill bit, drilling through the pilot hole and starting the hole in the
mating swivel.
2) Switch your drill bit to a smaller size (3/16” or ¼”) and drill partially through the tower,
making sure to stay centered in the pilot hole.
3) Switch your drill bit back to the 8mm bit and drill through the smaller hole.
4)
Continue switching between drill bits until you have drilled completely through the
swivels.
Insert Item 15 through the hole, and tighten to 30 ft-lbs. At this point double check that
the tower is centered before drilling and installing the next bolt. Repeat the anchor bolt
installation on the other rear leg of the tower. Drill and install the second anchor bolt on
each of the mating swivels to complete the installation of the four anchor bolts. The
tower is now centered and locked into position. All four anchor bolts MUST be installed.

and back)
Drill all the way through the
mating swivels until you can
see through the tower.
