FLYWHEEL 3L1516 - Caterpillar

4. Move the marine gear control lever to the engaged position. Prevent the propeller from stalling or reversing the engine's rotation by gradually increasing engine speed as the clutch is engaged.5. Allow at least one second to allow complete engagement of the clutch.6. Gradually increase engine speed as needed.When the marine gear selector lever is moved to the engaged position, the engine torque must be able to overcome the propeller and drive line inertia, the marine gear inertia and the propeller slip stream torque. On small horsepower engines, the drive line mass and inertia are usually light enough for the operator to control when reversing direction. Careless operation, however, can cause damage to the equipment. On large horsepower engines, a sequenced engine control system may be required. This equipment consists of a throttle boost with a shaft brake as optional equipment.The throttle boost system momentarily increases engine speed as the marine gear selector lever is moved from NEUTRAL to the engaged position. Upon completion of the clutch engagement, the throttle boost is released and the governor setting regulates the engine speed.The shaft brake stops the propeller shaft rotation when both clutches are disengaged with the selector lever in the NEUTRAL position. The shaft brake should be able to stop approximately 75% of the full rated shaft torque and should be able to stop the shaft within 3 seconds during a full power reversal.Engine And Marine Gear Operation
Full Load Operation
Move the governor control to full engine speed. An engine having fuel settings for continuous operation, can operate at full engine speed for long periods of time without shortening engine life.Pleasure Craft Operation
An engine having pleasure craft fuel settings, should not be operated for a period longer
