Where should transducer be mounted?

Transducer placement should be aft and close to the centerline. It needs to be located low enough that the transducer is in the water at all times. Consider items such as the lifting strap placement into the location as well as trailer bunks and rollers if it is a trailered vessel.

How far below the boat should a transducer be?

The transducer should be even with the bottom of the boat or slightly below the bottom. Leading edge (the edge closest to the transom of the boat). One click too high: the transducer is tilted out of the water and cannot maintain a sonar signal.

How far away from motor should transducer be?

The ideal mounting location on a boat powered by an outboard or an I/O engine is about 18-24 inches starboard of the engine’s lower unit. If the boat has inboard power, mount the transducer far enough to starboard to clear any propeller turbulence.

How far down do you mount the transducer?

You should mount your transom-mount transducer parallel to the waterline. While the vessel is moving, the device should extend into the water 3.5 mm (0.125 in.) below a fiberglass hull or 10 mm (0.375 in.)

What side of boat should transducer be on?

The general rule of thumb is to mount the transducer to the starboard side, which is the down stroke of most single outboard boat propellers (right hand lower unit). This side produces the least amount of turbulence and is most efficient in delivering the best performance.
