3. When the transducer is less that 2 ft 0 6 m from the bottom the depth readings may become inconsistent and erratic Manual Gain may be set too low which may cause weak bottom echo or no fish signals If in Manual Gain try increasing the Gain Ensure the back of the bottom surface of the transducer is slightly lower than the front and the front is as deep in the water as possible in order to minimize the generation of bubbles through cavitation See the Transom Transducers Installation Guide Check the transducer and power cable connectors at the back of the display unit 3 4 Erratic Fuel Flow readings a The fuel flow transducer may have been mounted too close to the fuel pump or may be subject to excessive vibration Refer to the installation instructions supplied with the fuel transducer Check for leaks in the fuel line or in the fuel pickup in the tank The Flow filter value is not suitable for the engine Check that the value is not set to zero then try increasing the value until a steady flow rate is shown see section 17 5 3 5 There is no reading for fuel economy a The boat must be travelling through the water to generate an Economy reading Check that the paddlewheel on the transducer is spinning freely and that the two magnets in the paddlewheel are still in place are securely plugged in and the collars are locked in place The collars must be secure for watertight connection Inspect t
