82313M Mariner BEARING, NEEDLE

If no oil pressure is indicated, STOP the engine. If maximum coolant temperature is exceeded, STOP the engine. Engine damage can result.
Engine Oil Pressure - The oil pressure should be greatest after a cold engine is started. The typical engine oil pressure with SAE10W40 is 350 to 450 kPa ( 50 to 65 psi) at rated rpm.A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:
Remove the load.
Stop the engine.
Check and maintain the oil level.
Jacket Water Coolant Temperature - Typical temperature range is 83° to 95°C (181.4° to 171°F). The maximum allowable temperature at sea level with the pressurized cooling system at 48 kPa (7 psi) is 103 °C (217.4 °F). Higher temperatures may occur under certain conditions. The water temperature reading may vary according to load. The temperature reading should never exceed 7 °C (44.6 °F) below the boiling point for the pressurized system that is being used.A 100 kPa (14.5 psi) radiator cap may be installed on the cooling system. The temperature of this cooling system must not exceed 112 °C (233.6 °F).If the engine is operating above the normal range and steam becomes apparent, perform the following procedure:
Reduce the load and the engine rpm.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load.
Inspect the cooling system for leaks.
Tachometer - This gauge indicates engine speed (rpm). When the throttle control lever is moved to the full throttle position without load, the engine is running at high idle. The engine is running at the full load rpm when the throttle control lever is at the full throttle position with maximum rated load.
To help prevent engine damage, never exceed the high idle rpm. Overspeeding can result in serious damage to the engine. Operation at speeds exceeding high idle rpm should be kept to a minimum.
Ammeter - This gauge indicates the amount of charge or discharge in the battery charging circuit. Operation of the indicator should be to the "+" side of "0" (zero).
Fuel Level - This gauge indicates the fuel level in the fuel tank. The fuel level gauge operates when the "START/STOP" switch is in the "on" position.
Service Hour Meter - The gauge indicates total operating hours of the engine.Indicator Lamps
There are four main indicator lamps that are available.
Shutdown Lamp
Warning Lamp
Wait to Start Lamp (Glow Plug Warning Lamp)
Low Oil Pressure LampFor information, refer to this manual, "Monitoring System (Table for the Indicator Lamps)" for the sequence of operation of the shutdown lamp and the warning lamp.The function of the wait to start lamp is automatically controlled at engine start-up.The function of the low oil pressure lamp is controlled by the engine ECM. If low oil pressure is detected, the lamp will be illuminated. The reason for the illumination of the low-pressure lamp should be investigated immediately.All lamps will illuminate for 2 seconds in order to check that the lamps are functioning when the keyswitch is turned to the ON position. If any of the lamps stay illuminated, the reason for illumination should be investigated immediately.The glow plug warning lamp will flash in order to show that the engine is been held at low speed. This function will be performed at engine starting and the duration will depend on ambient temperature and engine temperature.Instrument panels and Displays
In order to monitor the engine a wide verity of instrument panels are available. These instrument panels can contain the indicator lamps and the gauges for the application. Also available are mini power displays and performance monitors. These displays and monitors can show the operator the following engine information.
