GT8HW-IH Transducer

Installation Instructions

Mounting Considerations

• On single thickness fiberglass hulls, the transducer should be

mounted in the bilge area near the keel and transom.

• The transducer should not be mounted aft of the water pickup

and other protrusions.

• The transducer should not be mounted over a strake.

• The transducer should be mounted over solid fiberglass, with

no dead air space or coring in the boat hull.

• The transducer should be mounted as flat as possible in the

boat hull.

• The maximum deadrise angle is 6 degrees.

TIP: You can search the Internet for marine electronics forums

and videos that can help you to select the best mounting

location.

Deadrise Angle

Deadrise is the angle formed between a horizontal line and a

boat hull at a single point. You can measure the deadrise angle

with a smartphone application, an angle finder, a protractor, or a

digital level. You can also ask your boat manufacturer for the

deadrise angle of the specific point on your boat hull.

NOTE: A boat may have several deadrise angles depending on

the shape of the hull. Measure the deadrise angle only at the

location where you plan to install the transducer.

Tools Needed

• 80-grit sandpaper

• Marine-grade, quick-curing epoxy

• Rubbing alcohol

Testing the Mounting Location

Before you permanently mount the transducer, you should test

the transducer feedback at your mounting location with the boat

in the water. You should compare the transducer feedback at

your mounting location to the transducer feedback when the

bottom of the transducer is submerged outside the boat.

1Place the transducer inside a thin plastic bag.

2Fill the bag with enough water to cover the bottom of the

transducer, and secure the bag with a zip tie.

3Wet the surface of the hull.

4Place the bagged transducer on the mounting location.

5Observe the feedback of the transducer on your chartplotter

or fishfinder.

6If the transducer does not function as expected, select a new

mounting location and repeat steps 3 through 5.

Installing the In-Hull Transducer

1Sand the tested mounting location (Testing the Mounting

Location, page 1) with 80-grit sandpaper.

2Clean the tested mounting location with alcohol.

3Lightly sand the bottom of the transducer, and clean the

transducer with alcohol.

4Remove the release liner from the foam mounting ring

À, and

press the ring firmly onto the mounting surface.

5Fill the mounting ring one-third full of prepared quick-cure

epoxy Á.

6Slowly and firmly press the transducer Â into the ring,

removing air bubbles to ensure sonar signal strength.

NOTE: The epoxy should rise to the top of the foam ring, and

cover the lower part of the transducer housing to ensure

maximum signal coupling and secure the transducer.

7While applying pressure, slowly rotate the transducer one

quarter turn.

8Hold until the epoxy thickens, then place a weight on the

transducer, or tape the transducer in place, until the epoxy

hardens.

NOTE: The epoxy will cure in 24 hours.

9Route the cable, and connect the transducer to your

chartplotter or fishfinder.

NOTE: Do not operate the transducer until the epoxy has

fully cured.
