Step 2: Mounting Location
Determine where the tower will mount on your boat. The tower requires a 16x3 inch flat mounting surface on
top of the boat. Once you determine where you will mount the bases reinforce the back side of the boat with
the 3/8” marine grade plywood. 3M 5200 adhesive works well to hold the plywood in place.
Cut out the holes on the provided templates. The 5/8” diameter holes are where the studs will go through the
boat. The 13/16” h
ole is for your navigation light, speaker wires, etc...
Once you have cut out the template, use masking tape to hold the template in place and line up the starboard
template with the port.
Use
a 5/8” drill bit
to drill out the two stud holes for each base. Be sure to drill in reverse to get through the
gel coat, this will prevent spider cracks from forming. Once you are through the gel coat you can drill
normally. Determine which side of the boat the navigation
light needs to run to and drill the 13/16” hole
according to the template.
Step 3: Base Installation
Remove the paper templates and place the correct rubber gasket over the mounting area. Note that there is a
port and starboard gasket. The male deck mount (pc.7) will go below the female deck mount (pc.6). Placing
these over the holes then placing the gasket on top will make base installation much easier.
Slowly place the cast base on the boat. Be careful not to let the studs
come in contact with the gelcoat. Once the base is sitting on the boat
you can place the backing plates (pc.9) against your marine grade
plywood and tighten them down with the brass nuts (pc.4).
