also make sure there is enough room behind the unit to attach the
power and transducer cables. (A drawing on the next page shows the
dimensions of a gimbal-mounted sonar unit.)

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 fiber-
glass panels to reinforce the panel and secure the mounting hardware.

Install the gimbal bracket. Orient the bracket so the arms slope toward

the front of your unit.

Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer
cables. The best location for this hole is immediately under the gimbal
bracket location. This way, the bracket can be installed so that it covers
the hole, holds the cables in position and results in a neat installation.
Some customers, however, prefer to mount the bracket to the side of the
cable hole — it's a matter of personal preference.

After drilling the hole, pass the transducer connector 

up

 through the

hole from under the dash. Pass the power cable's bare-wire end 

down

though the hole from the top.

If you wish, you can fill in the hole around the cables with a good ma-
rine caulking compound. (Some marine dealers stock cable hole covers
to conceal the opening.) No matter what type of installation you prefer,
be sure to leave enough slack in the cables to allow tilting or swiveling
