Hull features that generate turbulence can affect your transducer's performance and cause it to wear prematurely. In general, if you use your transom-mount transducer while operating at higher speeds, you should mount the transducer close to the keel (centerline of the boat).

You should avoid mounting the device on the transom aft of or near parts of the hull that agitate the water. For example, the propeller , strakes , rivets , steps , and ribs agitate the water and create air and bubbles.

Fittings and water intake or discharge ports also generate turbulence. If you must install the transducer directly aft of a thru-hull fitting, you should mount the transducer at least 1.2 m (4 ft.) aft of the fitting.

If air and bubbles affect your transducer's performance, you should check the installation instructions and verify that the transducer is mounted and adjusted properly. You should also check the hardware to verify it is not bent.
