STEP 1: Choosing a Mounting Location
To obtain the best performance, the transducer should be mounted in a location where the water flow beneath the hull is aeration and turbulence-free. Try to mount the transducer as close to the center line of the boat as possible. Consult the boat manufacturer for the best in-hull transducer placement. If this information is unavailable, follow the guidelines below.
- On a single drive outboard or inboard/outboard boat, mount on the starboard side at least 4" beyond the radius of the propeller.
- On a twin outboard or inboard/outboard boat, mount between the drives, making certain that the transducer is not directly in front of either drive or propeller (avoid aligning directly in line with the bottom of the boat if the hull comes to a point).
- On an inboard boat, mount as far to the port or starboard as possible so that the propeller turbulence does not effect the performance of the sensor.
- On a single jet drive boat, mount on the starboard side at least 4” outside the intake grate.
- On twin jet drive boats, mount on the center line, between the intake grates (avoid aligning directly in line with the bottom of the boat if the hull comes to a point).
- On sailboats, mount on the starboard side at least 6" outside the keel.
- On pontoon boats and catamarans, mount on the starboard hull at least 2" outside the hull protector or center line.On PWC's, mount on the starboard side, at least 2" outside the intake grate.
STEP 2: Mounting and Adjusting
Align the included shims to achieve a slight angle as per the picture below. To prevent aeration, NEVER position the transducer in a manner that the Leading Edge (bow) is LOWER than the Trailing.
Do not allow the leading edge of the transducer to extend more than 1/8"(3 mm) of an inch below the bottom of the boat as this will create increased aeration and turbulence.
