889557 Mercury PLUG, Driveshaft Housing

DO NOT USE ETHER (starting fluids) unless specifically instructed to do so. If the engine is equipped with an Air Inlet Heater (electrically or fuel ignited manifold heater), DO NOT use ether (starting fluids) at any time. The use could result in engine damage and/or personal injury.
Startability will be improved at temperatures below 10°C (50°F) from the use of a cylinder block coolant heater or from other means that are used to heat the crankcase oil. This will help reduce white smoke and misfire during start-up in cold weather.
When using ether (starting fluid), follow the manufacturer's instructions carefully, use it sparingly and spray it only while cranking the engine. Excessive ether can cause piston and ring damage. Use ether (starting fluid) for cold weather starting purposes only.
For engines that are not equipped with an Air Inlet Heater, use ether when temperatures are below 0°C (32°F). If the engine is equipped with an injection system for starting fluid, crank the engine. Depress the ether switch for three seconds. Additional injections may be necessary in order to start the engine.Note: If the engine has not been run for several weeks, fuel may have drained. Air may have moved into the filter housing. Also, when fuel filters have been changed, some air will be left in the filter housing. Refer to the Operation and Maintenance Manual, "Fuel System - Prime" (Maintenance Section) for more information on priming the fuel system.
Disengage any driven equipment. This also reduces draining of the battery.
Turn the ignition switch to the ON position. The "CHECK ENGINE/DIAGNOSTIC" lamp will flash while the engine is cranking. The lamp should turn off after proper engine oil pressure is achieved. If the lamp fails to flash, notify your authorized Caterpillar dealer. If the lamp continues to flash, the Electronic Control Module (ECM) has detected a problem in the system. Refer to the Operation and Maintenance Manual, "Diagnostic Flash Code Retrieval" for more information on the engine diagnostics.
Push the start button or turn the ignition switch to the START position in order to crank the engine. Do not push down or hold the throttle down while the engine is cranked. The system will automatically provide the correct amount of fuel that is needed to start the engine.
If the engine fails to start within 30 seconds, release the start button, or the ignition switch. Wait for two minutes in order to allow the starting motor to cool before attempting to start the engine again.
Oil pressure should rise within 15 seconds after the engine starts. Do not increase engine speed until the oil pressure gauge indicates normal. If oil pressure is not indicated on the gauge within 15 seconds, DO NOT operate the engine. STOP the engine, investigate and correct the cause.
Note: The "CHECK ENGINE/DIAGNOSTIC" lamp may come on after the engine is started. If this occurs, the Electronic Control Module (ECM) has detected a problem with the system. Refer to the Operation and Maintenance Manual, "Diagnostic Flash Code Retrieval" for more information on the engine diagnostics.
Allow the engine to idle for approximately three minutes. Idle the engine until the water temperature gauge has begun to rise. Check all gauges during the warm-up period. Note: The oil pressures and fuel pressures should be in the normal range on the instrument panel. Do not apply a load to the engine or increase engine rpm until the oil pressure gauge indicates at least normal pressure. Inspect the engine for leaks and/or unusual noises.
After the ECM has completed the cold mode (or the cold mode is disabled), it cannot be enabled again until the ECM is powered OFF.
The cold start strategy will be activated when the coolant temperature is below 18°C (64°F). The cold start strategy will continue until the coolant temperature reaches 18°C (64°F), or until the engine has been running for fifteen minutes.If the cold start strategy is active and if the ECM measures engine rpm, the engine power that is available is reduced.A timer will disable the cold start strategy after a maximum time of five minutes. The time that is needed for the engine to reach the normal mode of operation is less than the time taken for a walk-around inspection of the engine.The ECM automatically idles the engine at 800 rpm for the correct warm up time after a cold engine start. The ECM checks the engine coolant temperature sensor. The ECM will adjust the idle rpm to the programmed low idle rpm when the engine is warm enough to operate properly.After the cold start strategy is completed, the engine should be operated at a low rpm and at low power until a normal operating coolant temperature of 79 to 98°C (174 to 205°F) is achieved. The engine will reach an operating temperature faster during a low engine rpm and during a low power demand. This procedure is more effective than idling the engine at no load. The engine should reach operating temperature in a few minutes.
