Optional R-A-M mounting system.
Bracket Installation
Mount the unit in any convenient location, provided there is clearance
behind it when it's tilted for the best viewing angle. You should also make
sure there is enough room behind it to attach the power, transducer and
GPS antenna/receiver module cables.
Holes in the bracket's base allow wood screw or through-bolt mounting.
You may need to place a piece of plywood on the back side of thin fiberglass panels to reinforce the panel and secure the mounting hardware.
Front
Install the gimbal bracket. Orient the bracket so the arms slope toward
the front of your unit.
