2. Inspection and adjustment
30R1
2.2.4 Inspection every 100 hours six months
Be sure to check the following points every 100 hours or six months operation, whichever comes first.
(1) Replace the lube oil in a sail drive.
Refer to the sail drive operation manual for the procedure of replacing the oil.
2.2.5 Inspection every 150 hours or one year
Be sure to check the following points every 150 hours or one year operation, whichever comes first.
(1) Replace the engine lube oil
During the operation of an engine, the oil deteriorates by the high temperature of the engine and is
contaminated due to the wear of internal parts. The lube oil must therefore be replaced periodically. It is
easiest and most effective to drain the engine lube oil after operation while the engine is still warm.
Beware of oil splashes if extracting the Lube oil while it is hot
1) Remove the lube oil dipstick and also the oil filler
cap at the top of the rocker arm cover. Attach the
oil drain pump to the dipstick guide and drain off
the lube oil.
[Notice]
For easier draining, remove the oil filler cap (yellow)
at the top of the rocker arm cover.
When lube oil is absorbed without removing a oil filler
cap, negative pressure grows big in the crankcase
and it may cause the rubber of the diaphragm
cracked.
2) Fill with new lube oil
.
3) Perform a trial run of the engine and check the oil
leakage.
4) Approximately 10 minutes after stopping the
engine, check the oil level by using the oil dipstick.
Add oil if the level is too low.
Standard
The level shall be between the upper and lower limit
lines on the dipstick.
[Notice]
When checking the 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 after removing the oil filler cap or about 10 minutes later after stopping the engine.
(2) Replace the marine gear lube oil.
Refer to 2.2.2(3) for the procedure.
