Shifting The Engine; Switching To Trolling (Kmh4A Only) - Yanmar 3JH5E Operation Manual

ENGINE OPERATION

Shifting the Engine

WARNING! Sudden Movement Hazard.
The boat will start to move when the
marine gear is engaged:
• Ensure the boat is clear of all
obstacles forward and aft.
• Quickly shift to the FORWARD position
then back to the NEUTRAL position.
• Observe whether the boat moves in
the direction you expect.
NOTICE: Shifting the marine gear while
operating at high speed or not pushing the
handle fully into position (partial
engagement) will result in damage to marine
gear parts and abnormal wear.
1. Before using the marine gear, be sure to
move the throttle handle to a low idle
position (less than 1000 rpm). Move the
throttle handle slowly to a higher speed
position after completing clutch
engagement.
2. NOTICE: NEVER shift the marine gear
at high engine speed. During normal
operation, the marine gear should only
be shifted with the engine at idle. When
moving the handle between FORWARD
(Figure 2, (1 or 3)) and REVERSE
(Figure 2, (3 or 1)), bring the clutch to
NEUTRAL (Figure 2, (2)) and pause
before slowly shifting to the desired
position. NEVER shift abruptly from
FORWARD to REVERSE or vice versa.
NOTICE: When sailing, set the remote
control lever in NEUTRAL. Not doing so
WILL introduce slippage or any damage
and void your warranty.
