Silicone Sealer, Ruler, Hole Saw 1 1/4", Drill Bit 5/16" or Step
Find and mark center
of mount location
Use the 1 1/4" hole
saw to cut center hole - save cutout and shavings, can be used to
repair punctures or cracks
Insert mount from the
inside, slide the spacer over the mount and carefully mark location
of the 5/16" holes - remove the mount and spacer and check your
marks - there is very little room for error here as you can see in
Drill the 5/16"
locating holes - a step drill is great for this - if you use a
regular drill bit I recommend drilling a 3/16" pilot hole before
drilling the 5/16" holes.
Apply a generous
amount of Silicone Adhesive/Sealer to the mount and install it
through the 1 1/4" hole, line up the 5/16" locating pins and seat
the mount in the hull. Apply sealer to the spacer and install it
and the nut inside the hull. Tighten the nut securely and install
the bottom cap.
Clean the excess
sealer from the mount and the job is done.
