Typically the engine and propeller generate turbulence at the stern near your transom-mount transducer. These placement recommendations can help avoid interference from turbulence.

• On boats with outboard or inboard/outboard motors, you should mount the transducer as close to the centerline of the transom as possible, but at least 38 cm (15 in.) from the propeller.

• If the propeller rotates in a clockwise direction, mounting the transducer on the starboard side typically yields the best results (Direction of Propeller Rotation).

• If the propeller rotates in a counter-clockwise direction, you should mount the transducer on the port side.

• On single-drive boats, you should not mount the transducer in the path of the propeller because the resulting turbulence and cavitation can damage the propeller.

• On twin-drive boats, you should mount the transducer between the drives, if possible.
