1. Connect the hoses as shown above
2. Remove the plug from the upper case
cover (Figure 9, (1)).
3. Operate the pump to fill the Sail-Drive
with oil. Be aware that oil has to flow
down through restricted parts of the
casing and then back up again, so
pressure will initially be high and
pumping will be difficult. Pausing for a
few minutes will help. The hand pump
and rubber hose are available from
Yanmar, and are optional parts for
SD50 / SD50-4T. Any type of hand
pump or rubber hose (inner diameter
14 to 16 mm [0.5 to 0.625 in.]) available
locally can be used.
4. After filling, first screw in and tighten the
plug at the top cover. Then remove the
hand pump, hose and adapter joint and
screw in the oil plug with a gasket.

3. Attach a stiff rubber hose with an inner
diameter of 14 to 16 mm
(0.5 to 0.625 in.) with hose clamps to the
adapter joint at the oil drain position. The
hose must be long enough to drain to the
bucket.
4. Remove the dipstick and oil inlet plug
from the upper case cover.
