Front view (left) and side view (right) showing dimensions of sonar
unit mounted on gimbal bracket.
Drill a 5/8" (15.9 mm) hole in the dash for the power/transducer cable.
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 cable 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 connector up through the hole from under the dash.
If you want, you can fill in the hole around the cable with a good ma-
rine sealant 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 cable to allow tilting or swiveling the unit.
If you choose to fill in the cable hole, be sure to position the cable
against the rear edge of the hole as you apply the fill material.
Before positioning the gimbal bracket, be sure to hold the cable against
the rear edge of the hole. Then, slide the bracket over the hole and butt
the rear of the bracket base firmly against the cable, thus pinning it in
place against the side of the hole. Finally, fasten the bracket to the
dash.
