[Notice]
When checking the lube oil level right after the engine running, the oil level in the dipstick guide
decreases drastically, and the accurate oil measurement can't be performed because the pressure in
the cylinder block decreases with the function of the diaphragm in the rocker arm cover. Therefore,
measure the lube oil level about 10 minutes later after stopping the engine or after removing the oil
filler cap.
Note:
The yellow label shown right is attached on the
dipstick.
(3) Replace the marine gear lube oil.
During initial operation, the oil is quickly contaminated due to the initial wear of internal parts. The lube
oil must therefore be replaced early.
Refer to the sail drive operation manual for the procedure of replacing the sail drive lube oil.
1) Remove the cap from the filler port and attach the oil drain pump. Drain off the oil.
2) Fill with new lube oil.
