Information:

Trolling
The trolling valve is an attachment to the marine transmission and operates only in the forward direction. With the trolling valve engaged, engine speed must not exceed 650 RPM. The marine transmission oil temperature must not exceed 180°F (82°C). It may be desirable to mark the tachometer and oil temperature gauges at these two limits as a warning reminder. Proper monitoring of these gauges is necessary to prevent heat build-up in the clutch plates.Trolling at reduced load for several hours may cause oil consumption and carbon build-up in the combustion chambers. Every 4 hours, load the engine at full speed and burn the carbon from the combustion chambers.Stopping
Before stopping the propulsion engine: 1. Reduce engine speed to low idle with the transmission clutch engaged.2. Check the transmission oil level with the engine running.3. Maintain oil level between the ADD and FULL marks on the oil dipstick.4. Move the transmission control lever to neutral position and stop the engine as per manufacturer's instructions.After Stopping Checks and Procedures
1. Drain the sea water system if below freezing temperatures are expected;2. Observe the service meter reading. Perform the periodic maintenance as instructed in the LUBRICATION AND MAINTENANCE CHART.Alarm Switches
Each alarm switch is electrically connected to an indicating light, bell or horn. The alarm will continue until the condition is corrected and then the light, bell or horn will turn off.To silence the bell or horn while repairs are being made, a two-way switch and a red indicator light may be installed. When the alarm is turned OFF, the red indicator light will light.

Marine Transmission Oil Pump Failure
Marine transmissions have a lubrication system which is independent from the engine lubrication system. The Caterpillar 7200 Series Marine Transmissions may be equipped with an emergency lubricating oil system, as shown in the illustration, which can provide proper lubrication to the marine transmission should the marine transmission oil pump fail. 1. Emergency Lube Oil Valve2. Marine Transmission Case3. Tapped Holes in Marine Transmission Case4. Strainer5. Emergency Lube Oil Pump6. Output FlangeWhen the marine transmission oil pump fails, engagement of the clutches will become sluggish and the clutch plates will slip or disengage. The shaft bearings will not receive pressure lubrication.To use the emergency marine transmission oil pump:1. Stop the engine.2. Loosen, move and bolt the handle of the emergency valve (1) into the EMERGENCY position.
EMERGENCY LUBE OIL VALVE3. Start the emergency lube oil pump (5).4. Observe the reading of the marine transmission oil pressure gauge.5. Check the marine transmission oil level with the emergency pump running.6. Maintain the oil level at the FULL mark on the dipstick.7. If the engine is not to be started (if the vessel is going to be towed by another vessel) the propeller can
