Whether you’re a diehard angler, a casual fisherman, or a weekend cruiser, you probably have or would like to have a fishfinder onboard, so installing or replacing a fishfinder is a job you’ll probably tackle sooner or later. Lucky for us, when it comes to binnacle-mounted units that use
transom-mounted transducers — the most common fishfinder installations
on the water — this is an easy DIY job you can handle. All you need are a few
tools and the know-how, which you’ll find right here on these pages.
STEP I: INSTALLING THE BINNACLE MOUNT
Before you begin this mounting job, you’ll need to find the best location. Try to keep the
fishfinder as close as possible to center on the helm, which provides the best viewing angle.
The unit should be between waist- and shoulder-high; stay away from overhead mounting
locations such as in an electronics box or hanging down from a hard-top, which will force you
to crane your head back when using the unit
and may lead to neck strain. Also, make sure
the location allows you to tilt and/or turn the
unit without hitting the windshield, throttle,
compass, or other affixed items.
TECH TIP: AFTER SECURING THE SPADE OR RING CONNECTORS TO YOUR FUSE BLOCK, SPRAY THEM DOWN
WITH A GOOD CORROSION INHIBITOR, LIKE BOESHIELD T- 9 OR CORROSIONX.
