Switching To Trolling (Kmh4A Only) - Yanmar 3JH4E Operation Manual

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)) and
REVERSE (Figure 2, (3)), bring the
clutch to NEUTRAL (Figure 2, (2)) and
pause before slowly shifting to the
desired position. Do not shift abruptly
from FORWARD to REVERSE or vice
versa.
Switching to Trolling (KMH4A
only)
Use the trolling handle to begin trolling.
When changing from FORWARD or
REVERSE to trolling, the speed of the
propeller revolution will be reduced to a
minimum.
NOTICE: When trolling, do not increase
engine speed above 1000 rpm. This may
cause premature wear and damage to the
clutch.
