4 Mounting the transducer Transducer location selection and installation are two of the most critical steps in sonar installation. To function properly the transducer must be in the water at all times, and in a location that has a smooth flow of water when the boat is moving. Research Before starting the installation of the transducer, it's advised to check the following; • Find out if the boat builder has a recommended installation location • Establish direction of rotation of the propeller(s) • Watch actual water flow when boat is travelling at cruising speed to determine the area of transom with cleanest flow (least bubbles) Select a transducer location The primary aim is to stay clear of propeller and hull generated turbulence, while mounting the transducer as close to the center of the vessel as possible. 14 | 1 23 4 5 1 Avoid mounting within 1m (3.3') to port of propeller 2 Conventional clockwise propeller rotation 3 Avoid mounting within 7.5cm (3") to starboard of propeller 4 Best mounting location - undisturbed water flow 5 Planing strake - avoid mounting behind here ¼¼ Note: Reverse the distance guides (1 & 3) from propeller where engine is of counterclockwise configuration.
