Transducer Location

Nearly every boat sold today has a transducer installed by either the factory or a dealer. Many have more than one mounted in their hulls.

The majority of these boats have no factory provisions for mounting locations, leaving it up to the installer to determine a location that will not negatively affect boat performance.

Improperly or poorly installed transducers can compromise engine cooling, cause cavitation to propellors and water intakes, and adversely affect vessel steering and handling.

1. Transom-mounted transducers are often found on trailered boats.

2. Examine the hull for protrusions that may cause turbulence to flow back towards the transducer.

3. Check the water flow under way before installation to look for signs of turbulence.

4. The propellor rotation direction must be taken into account.

5. For twin engines, mount the transducer in the center.

6. In-hull transducers do not cause drag and never become fouled, but lack a temperature sensor.

7. They should be installed in solid fiberglass hulls. Some boats with cored hulls have special solid areas specifically for transducer installation.

8. It is important to make sure there is always water outside the chosen location.

9. Avoid areas that might cause interference with the signal.

10. Accessibility is important for maintenance.

11. For through-hull transducers, ensure there is a clean run of water over the location.

12. Lifting straps when the boat is hauled are a common cause of damage to through-hulls with fairings.

13. For tilted, low-profile through-hulls find a location at the right hull deadrise angle, with a clean water flow.
