Reverse Gear

The reverse gear is hydraulic, which means that
shifting between ahead/astern and neutral is
performed hydraulically. The reverse gear lubrication
system is equipped with an oil filter and oil cooler. The
reverse gear uses solenoid valves for electronically
controlled shifting.
Bukh recommends that a seawater filter be fitted to
guarantee the correct cooling water flow to the engine
and reverse gear. Otherwise there is a risk of
contaminants in the seawater blocking the reverse
gear cooler and other cooling system components.

Oil level, checking and topping up

1 Start the engine and let it run on idle a few minutes.
2 Remove the dipstick by turning counter-clockwise.
3 Wipe the dipstick and reinsert it in the reverse gear
without screwing it in. Remove the dipstick and
check the oil level. The correct oil level is between
the MAX and MIN markings.
4 Top up the oil as required using the dip stick tube.
Please refer to section Technical Data, page 133
for oil quality and capacity.
IMPORTANT:
Never over-fill the reverse gear. The oil level must
always be within the recommended range.
