Bukh D4 - Operation; Safe Operation and Instrument Reading

Maneuvering
Shifting
between forward and reverse is done at idling.
Shifting at higher engine speeds can be uncomfortable
for passengers and cause unnecessary stress on the
transmission or cause the engine to stop.
If you attempt to shift gear at a high engine speed, a
safety function is automatically activated, and will
delay shifting until engine speed has fallen to 1000
rpm.
Execute a Forward/Reverse Operation as Follows:
1 Reduce engine speed to idle and let the boat, more
or less, lose way.
WARNING!
Never shift to reverse when the boat is planing.
2
Move the control lever to Neutral (N) with a rapid,
distinct movement. Make a brief pause.
3 Move the control lever to Reverse (R) with a rapid,
distinct movement and increase engine speed.
IMPORTANT:
To avoid water entering the stationary engine via the
exhaust
pipe, it is important that all engines are running
during reverse maneuvers.
