3. Operation
3.1.2 Lube Oil
NOTICE
Using other than the specified
lube oil will lead to seizure of
parts, abnormal wear, and shorten
engine life.
(1) Selection of Engine Lube Oil
Use the following lube oil:
• API Classification ............................. CD
(2) Selection of Oil for Marine Gear
• API Classification ............................. CD
(3) Selection of Oil for Sail Drive Unit
SAE Viscosity ................... 90 or 80W90
(4) Handling the Lube Oil
1) When handling and storing lube oil, be
careful not to allow dust and water to
enter the lube oil. Clean around the
filter port before refilling.
2) Do not mix lube oils of different types
or brands. Mixing may cause the
chemical characteristics of the lube oil
to change and lubricating performance
to drop, reducing the engine's life.
Before supplying lube oil to the engine
and marine gear for the first time,
extract all the lube oil already in the
tank. Use new lube oil.
3) Lube oil supplied to the engine will
undergo natural degeneration with time
even when the engine is not used.
Lube oil should be replaced at the
specified intervals, regardless of
whether the engine is being used or
not.

3.1.3 Cooling Water
It is important to check the cooling water
daily. Be sure to use clean soft water (tap
water) for cooling fresh water.
NOTICE
Be sure to add antirust or anti-
freeze to cooling fresh water.
In cold seasons, the antifreeze is
especially important.
Without antirust, cooling perfor-
mance will drop due to scale and
rust in the cooling water system.
Without antifreeze, cooling water
will freeze and expand, breaking
various parts.
For your reference, antifreeze
mixed with antirust is now avail-
able in the market.
