Propeller Equipment; Sail Drive - Bukh DV36 ME Owner's Handbook Manual

OPERATING MANUAL FOR BUKH DV36ME ENGINES
Propeller equipment (As supplied by BUKH – for other types
consult individual manufacturer's instructions)
Flexible stern tube: Every three years replace the three seal rings in the
stuffing box "A" and the rubber hose "B" connecting stuffing boxand inter-
mediate tube "C" . Fill the flexible stuffing box "A" with Out-board gear oil
through the filler hole in this or via the automatic stern tube lubrication "D"
supplied as extra equipment to the stern tube arrangement.
Normally the consumption of Out-board gear oil is not considerable, and
therefore, a sudden increase indicates defectivesealing rings.
The container "D" should be mounted about 0.25 m above the water line.

Sail drive

As an alternative to the marine gear, the engine can be
equipped with a sail drive. The sail drive has the same
function as the reverse-reduction gear.
The reduction is 2.25:1 for AHEAD and for REVERSE.
The sail drive will need no other attention than regular
change of oil. Change of oil should be carried out after
the first 25 hours of operation, then every 150 hours or
once a year.
Carry out the oil change when the boat is on land by
loosening the screw "D" in the bottom of the drive,
enabling the oil to run out.
Refill the fresh oil to a quantity of 3.3 ltr. through the filter
hole "B" at the top of the drive corresponding to the
upper mark on the dipstick "A".
Use the same quality of oil as indicated iunder
"Technical Data" for the marine gear.
A replaceable zinc anode "C" is fitted on the sail drive.
Check this anode once a year, replace it in case of
considerable corrosion.
Only use a propeller which is insulated from the shaft
and the leg!.
Check that there is good electrical connection between
the zinc anode and the bearing hub through the two
mounting screws.
The sail drive is equipped with a double diaphragm "F"
preventing penetration of seawater. In the double
diaphragm a sensor "E" is fitted which releases an
acoustic alarm if water penetrates between the two
diaphragms. It is important for the sake of safety that this
alarm is always serviceable. It should be checked twice
a year by short-circuiting the connections 1 and 2 on the
plastic box next to the multiple plugs.
When short-circuiting here by means of a piece of wire
or a screw-driver, the buzzer should give alarm.
The aluminium housing of the sail drive has been
specially treated on the outside. Damage to surface
treatment should be treated as soon as possible with
special BUKH paint. The sail drive should be coated
with the same paint as the rest of bottom of the boat.
This paint must not contain copper.
