Warning lights and audible alarmYour boat with the STEYR MOTORS Marine Engine engine is equipped with three warning lights and one audiblealarm (mounted behind the instrument panel) to indicate the following operation condition or system deficiencies.(The ECU will also reduce the engine power in case an important operating parameter limit has been exceeded).* Indication Pre-warming Phase (combined indication through oil pressure light. Becomes affective if ambientengine coolant temperature is below 20 °C/68 °F)* Break – In; over load warning* Engine oil pressure too low* High coolant temperature* Sensors or sensor circuit defectAfter ignition is turned “ON” the indication/warning lights are illuminated and the warning horn will sound for less thena second (0.7 sec.) this serves as a functional check for the optical/audible warning system.The indication light and the warning horn remain switched on for 5 sec. after ignition “ON” if a sensor or sensor circuitdefect have been detected and stored in the Engine Control Unit (ECU) (see section Instrument Panel).Please contact your nearest STEYR MOTORS Marine Dealer to get proffesional assistance to verify the deficiencyand to correct any possible failure.If the engine oil pressure is too low, the warning light “engine oil pressure” lights and the audible alarm sounds. Theengine power will be limited. In this case proceed as follows:* Check engine oil level, respectively add engine oil if necessary (refer to chapter Fuel and Lubricants)* Restart engine and watch the oil pressure light. The warning light has to extinguish within 3 or 4 second after thestart. If this does not happen the engine must be stopped immediately. (Ignition “OFF”)In case of an overheating of the exhaust gas cooling system, the warning light “engine control” flashes and the audiblealarm sounds (2 times per second); the engine power is reduced. In this case, proceed as follows:* IMMEDIATELY reduce the engine to idle speed.* Check an clean the raw water filter.* Check the coolant temperature gauge for overheating of engine coolant. If the coolant temperature gaugeindicates overheating of engine coolant, switch for a short time to REVERSE to remove a possible clogging ofthe raw water inlet through large plastic parts etc., and then to FORWARD. Let the engine run at idle speedfor some minutes. If the temperature gauge still indicates an overheating of the engine, the engine is to bestopped. Restart the engine only after having found and eliminated the cause for alarm. See “loss of power” inTrouble Shooting Chart, Technical Data and in section Maintenance. Check coolant level and if necessary,refill coolant until an adequate coolant level is achieved. If the cause for optical/audible alarm cannot be found,consult your STEYR MOTORS Marine dealer.31
