be pulling oil from the bearings: Severe damage will result.
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 than 5 minutes at full speed. When operated at full speed, the engine should then be operated for as long, or longer, at cruising speed. The engine can be operated at cruising speed for long periods of time without shortening engine life.Cruising Speed for Pleasure Craft Rated Engines
Recommended cruising speed for your pleasure craft rated engine is dependent upon exterior hull conditions, propeller shaft alignment, and propeller condition. Cruising speed must be determined each day the craft is operated.To determine the cruising speed for your engine:1. Start and warm the engine.2. Gradually increase the speed of the vessel until full speed is reached.3. Maintain full speed for approximately 4 minutes.4. Observe the maximum tachometer reading: This is maximum engine speed for the vessel under the existing conditions of the hull and propeller. These conditions can change daily.5. Reduce engine speed 200 to 300 RPM. This is the recommended cruising speed for your engine under present conditions.6. If it is necessary to increase engine speed, run at maximum engine speed for 5 minutes or less. Then operate for an equal period of time or longer at cruising speed (or slower) before increasing engine speed again. The slower speed is needed to allow the engine
