CONTROL GP-POWER TRAIN 1999847 - Caterpillar

Trolling speed is a function that is controlled by the ECM. The engine control is capable of limiting engine rpm to the programmed maximum trolling speed.The marine transmission may be equipped with a valve that controls trolling speeds. Refer to the operation manual for the marine transmission for the limits of the engine rpm during trolling.Note: Engine rpm and the marine transmission oil temperature must be within the limits that are specified by the operation and maintenance manual for the marine transmission.It may be acceptable to mark the tachometer and the oil temperature gauges at the trolling limits. Proper monitoring of the tachometer and oil temperature gauges is required in order to help prevent overheating of the clutch plates.Trolling at reduced load for several hours may cause excessive oil consumption and carbon buildup in the combustion chamber. This buildup results in poor engine performance and power loss. Load the engine at full rpm in order to burn the carbon from the combustion chamber. Perform this procedure at four hour intervals during service.Follow the OEM recommendations for operating attachments to marine transmissions for trolling.
