Where should a transducer sit on a boat?

The location should be as close to the center of the boat as possible, but on the side of the downward swing the propeller. On the majority of boats, this will be on the starboard (right) side.

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 should a transducer be in the water?

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.

What happens if transducer is mounted too low?

A transducer placed too low in the water will cause water to flow over the top of the transducer creating a rooster tail and creating air bubbles that will travel over the bottom of the transducer.

How far should transducer be from trim tabs?

Humminbird sticks by it’s policy that the transducer must be 15 inches away from props and should be as far as possible from trim tabs.

Does it matter which side of boat you mount a transducer?

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.
