Oil Change and Gear Ratio
As an alternative to the BW7 gear the DV36 can be equipped with a sail drive.
The reduction ratio is 2.25:1 for “AHEAD” and 2.25:1 for “REVERSE”.
The sail drive will need no other attendance than regular change of oil. This to be carried out after
the first 25 hours of operation and then every 150 hours or once a year.
Carry out the oil change when the boat is on land by loosening the drain screw in the bottom of the
sail drive enabling the oil to run out.
Refill with fresh oil through the filler hole at the top of the sail drive to a quantity of 3.3 litres
corresponding to the upper mark on the dip stick.
Use the same quality of oil as for the BW7 gear.
Zinc Anode
A replaceable zinc anode is fitted at the propeller. Check this anode twice a year or as required all
depending on the waters you are sailing in.
Outside Maintenance
Do not grind thoroughly when careening the boat. Damage to the surface treatment should be
treated as soon as possible with special BUKH paint.
The sail drive should be coated with the same bottom paint as the rest of the bottom of the boat.
