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.
