Mounting the Transducer on a Transom

When selecting a transom mount location, consider the following

for optimal performance:

• For your sonar to operate properly, the transducer must be

located in calm water. DO NOT mount the transducer behind

strakes, rivet lines, struts, ttings, water intake, discharge

ports, eroding paint, or anything that creates turbulence.

• Mount the transducer as close to the center of the boat as

possible.

• DO NOT cut the transducer lead. (This voids your warranty.)

• DO NOT mount the transducer in locations where it might

be jarred when launching, hauling, trailering, or storing.

• DO NOT mount the transducer in the path of the prop on

single-drive boats. The transducer can cause cavitation that

can degrade the boat’s performance and damage the prop. On

twin-drive boats, mount the transducer between the drives, if

possible.

DO NOT mount the transducer behind strakes, struts,

ttings, water intake or discharge ports, or anything that creates

air bubbles or causes the water to become turbulent. The

transducer must be in clean (non-turbulent) water for optimal

performance.
