16150-ZW0-000 Honda JET SET (#42) (Honda Code 4897773).

Engine Speed Governing
The engine speed governor monitors the throttle position and the actual engine speed in order to help control the following items: engine speed, response, torque output and smoke limiting. The engine speed governor also helps to maintain constant engine speed.The engine speed is controlled by the governing of the fuel injection duration of the electronic unit injectors. Throttle input is used to calculate the desired engine speed.Engine Synchronization
Engine synchronization connects the Electronic Control Module (ECM) of the port engine and the ECM of the starboard engine to a common throttle. Engine synchronization increases the convenience of the operator and the control of the vessel. This feature is standard in marine applications.The engine synchronization enables either throttle to be used in a backup situation. The operator can use a switch to transfer the control of both engines to either the port throttle lever or starboard throttle lever. Refer to the Installation Guide for more information on engine synchronization.Engine and Marine Transmission Operation
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 3 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.
Docking and Reverse Travel
Do not shift across the NEUTRAL position without a few seconds delay. The engine torque must be able to overcome the propeller and drive inertia, the marine transmission inertia, and the propeller slip stream torque.A direct through-shift will cause severe shock loads to the engine, marine transmission and hull. Also, it can cause the engine to reverse its rotation (run backwards). If the engine reverses rotation, the engine and marine transmission oil pumps will be running opposite normal rotation. Oil will not reach the bearings, and severe engine damage will occur.When reversing direction of travel (propeller rotation), reduce engine rpm to low idle. Place the transmission selector lever in the NEUTRAL position for approximately one second to allow the clutch plates to completely disengage and the propeller to stop turning. Move the transmission selector lever to the other direction and allow one second for the clutch to become fully engaged before increasing engine rpm.
Reduce engine rpm to a low idle.
Move the transmission selector lever to the NEUTRAL position. Wait for one second so that the clutch plates will disengage and the propeller will stop turning.
Move the transmission selector lever to the engaged position. Wait for at least one second so that the clutch will completely engage before the engine rpm is increased. The rotation of the marine transmission should not be changed at full engine rpm. Stopping the Vessel Temporarily
Use the following procedure for a temporary stop while the engine is running:
Reduce engine rpm to low idle.
Shift the marine transmission to the NEUTRAL position.
To resume travel, shift into the FORWARD position or the REVERSE position at low idle. Wait for at least one second so that the clutch will completely engage before the engine rpm is increased. Gradually increase the engine rpm. Slow Vessel Mode
Activating the slow vessel mode switch reduces the low idle to 550 rpm. The slow vessel mode should only be used for the following operations:
Docking
Tight maneuvering
Slow vessel operation in no-wake zones or similar circumstances
Excessive use of the slow vessel mode may cause battery discharge from some alternators.
Trolling Mode Strategy
This strategy limits the engine speed in order to help avoid high loads on the transmission during trolling.During trolling, moving the engine throttle to full throttle will cause the speed of the engine to change from a programmable low idle speed to a maximum programmable trolling speed. The maximum programmable trolling speed is a customer specified parameter.
Table 1
Programmable Range
Minimum Default Maximum
900 rpm 900 rpm 1200 rpm The trolling mode will only be activated or deactivated by the Electronic Control Module (ECM) when engine speed is within 50 rpm of the programmed low idle engine speed. The trolling mode can also be activated when the engine is not running.
