In-Hull Installation

To avoid drilling a hole to mount a thru-hull transducer, a transom

mount transducer may be used with epoxy inside a boat (also called "shoot-

thru-hull" installation). For a transducer to be mounted inside the hull

(shoot-thru, not thru-hull), the boat must be ﬁ berglass, no core (contact

your boat manufacturer if you are unsure). Test by placing a small amount

of water inside the hull, placing the transducer on top of the water, then

verifying the accuracy of the locators versus the current water depth. If

they are the same, use epoxy (non-silicone based) to afﬁ x the transducer

to the inside of the hull. If using a temperature sensing transducer, the

temperature displayed will reflect the hull temperature.

Selecting a Location

The location has to be solid ﬁ berglass, devoid of any air bubbles,

laminates, ﬁ llers or dead air space. The location needs to be in an

area of clean water at all speeds. Do not place the transducer over

any strakes or behind any obstruction on the hull that would create

turbulence.

Testing the Location

Place the transducer in the water, pointed directly at the bottom, and

set the unit for optimum performance. Place the transducer in the test

device as show on the side bar. If the sonar performance is signiﬁ cantly

degraded, another location will need to be tested.

Many modern hulls have a pre-located pocket for

In-hull transducer installation. If you are unsure

if your hull is equipped with a prelocated pocket,

contact your hull manufacturer.
