Transmission Selector Lever
Power is transferred from the engine through the marine transmission to the propeller shaft. The marine transmissions can be operated by using one of the following methods:
Mechanical
Hydraulic
Pneumatic
ElectricalA control valve directs the flow of oil to the forward clutch or to the reverse clutch. The control valve is operated by a transmission selector lever. The transmission selector lever can be manually operated or remotely operated.Normally, the marine transmission is operated from the pilot house. The controls of the pilot house must be adjusted in order to permit full travel of the transmission selector lever. This will also permit full engagement of the clutch plates.When the remote controls are properly adjusted, periodic clutch adjustment is not required.Moving and Getting Underway
For the best performance and the maximum service life, shift the transmission in the following manner:
Fully engage the marine transmission selector lever in the desired direction of travel.
Wait for at least three seconds in order to allow the clutch to engage completely before increasing the rpm of the engine.
Gradually increase engine rpm.
Operate the marine transmission controls ONLY with the engine running. A rotating propeller shaft with an engaged clutch is not lubricated sufficiently when the engine is not running, and may be damaged.
