0329833 EVINRUDE GASKET, Exhaust manifold

Always determine the cause of the engine shutdown. Make necessary repairs before attempting to restart the engine.
Be familiar with the following items:
Types and locations of shutoff
Conditions which cause each shutoff to function
The resetting procedure that is required to restart the engineAlarms
The alarms are electrically operated. The operations of the alarms are controlled by the ECM.The alarm is operated by a sensor or by a switch. When the sensor or the switch is activated, a signal is sent to the ECM. An event code is created by the ECM. The ECM will send a signal in order to illuminate the lamp.Your engine may be equipped with the following sensors or switches:Intake manifold air temperature - The intake manifold air temperature sensor indicates high intake air temperature.Intake manifold pressure - The intake manifold pressure sensor checks the rated pressure in the engine manifold. Fuel rail pressure - The fuel rail pressure sensor measures the high pressure or low pressure in the fuel rail. The ECM will Check the pressure.Engine oil pressure - The engine oil pressure sensor indicates when oil pressure drops below rated system pressure, at a set engine speed.Engine overspeed - If, the engine rpm exceeds the overspeed setting the alarm will be activated.Air filter restriction - The switch checks the air filter when the engine is operating.User-defined switch - This switch can shut down the engine remotely.Water in fuel switch - This switch checks for water in the primary fuel filter when the engine is operating.Fuel temperature - The fuel temperature sensor monitors the pressurized fuel in the high-pressure fuel pump.Coolant temperature - The coolant temperature sensor indicates high jacket water coolant temperature.Note: The sensing element of the coolant temperature sensor must be submerged in coolant in order to operate.Engines may be equipped with alarms in order to alert the operator when undesirable operating conditions occur.
When an alarm is activated, corrective measures must be taken before the situation becomes an emergency in order to avoid possible engine damage.
If corrective measures are not taken within a reasonable time, engine damage could result. The alarm will continue until the condition is corrected. The alarm may need to be reset.Note: If installed, the coolant level switch and the oil level switch are indicators. Both switches should only be operated when the application is on level ground and the engine RPM is zero.Clean Emission Module (CEM)
Diesel Oxidation Catalyst ____________________ (DOC)
Selective Catalyst Reduction ____________________ (SCR)
Diesel Particulate Filter ____________________ (DPF)DOC and SCR System
Temperature Sensor before DOC
NOx Sensor
SCR Temperature Sensor
Ammonia SensorTemperature Sensor before DOC - This sensor monitors the gas temperature that is entering the DOCNOx Sensor - Two NOx sensors monitor the NOx concentration within the exhaust gas before and after the SCR module. SCR Temperature Sensor - The sensor monitors the gas temperature entering the SCR.Ammonia Sensor - The sensor monitors the concentration of ammonia within the exhaust system after the CEM.The temperature sensor before DOC, NOx sensor, SCR temperature sensor, and ammonia sensor all connect with the engine ECM. If the signal from these sensors is out of the set range, the ECM will trigger an alarm for the operator. DOC, SCR, and DPF System
Temperature Sensor before DOC - This sensor monitors the gas temperature as the gas enters the DOCDPF Temperature Sensor - The temperature sensor monitors the temperature within the DPF.Soot Sensor Control - The soot sensor control unit monitors the amount of soot within the DPF. NOx Sensor - Two NOx sensors monitor the NOx concentration within the exhaust gas before and after the SCR module. SCR Temperature Sensor - The sensor monitors the gas temperature entering the SCR.The temperature sensor before DOC, DPF temperature sensor, soot sensor, NOx sensor, SCR temperature sensor, and ammonia sensor all connected to the ECM. If the signal from these sensors is out of the set range, the ECM will trigger an alarm for the operator. Diesel Exhaust Fluid (DEF) System Control
DEF Level Sensor - The DEF level sensor signals the ECM. The ECM determines the signal in order to give a level reading of the volume of fluid in the tank.DEF Temperature Sensor - The sensor signals the ECM. The ECM will determine the temperature of the DEF within the tank from the signals sent. The temperature of the DEF is important in order to keep the DEF injector operation correctly.Dosing Control Unit (DCU) - The DCU controls the injection of the DEF and will signal the ECM if the injection has been interrupted.The DEF level sensor, DEF temperature sensor, and the Dosing control unit all connect with the engine ECM. If the ECM determines that any of the signals are out of the specified range, an alarm will be triggered.Testing
Turning the keyswitch to the ON position will check the indicator lights on the control panel. All the indicator lights will be illuminated for 2 seconds after the keyswitch is operated. Replace suspect bulbs immediately.Refer to Troubleshooting for more information.
