Finder sonar unit when mounted on gimbal bracket.
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. Drop 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
the unit. If you choose to fill in the hole, be sure to position the cables
against the rear edge of the hole as you apply the fill material.
Before positioning the bracket, be sure to hold the cables against the rear
edge of the hole. Then, slide the bracket over the hole and butt the rear
