NOTICE
Do not run the engine with too much or
not enough oil in the oil tank, otherwise
the engine could be damaged.
Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
TIP:
When checking the engine oil level on land,
the engine must be running while water is
being supplied to the cooling water pas-
sages. (See "Flushing the cooling system"
on page 110 for information on supplying
water.)
When checking the engine oil level on wa-
ter, moor the boat so that it will not drift
away.
To check the engine oil level:
(1) With the engine stopped, place the boat
in a precisely level position on land or
launch the boat.
(2) Look in all directions, and then start the
engine. (See page 95 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 min-
utes or more. Run the engine an addi-
tional
5
minutes
temperature is 20 °C (68 °F) or less.
(4) Stop the engine.
(5) Open the engine hood. (See page 55.)
(6) Loosen the oil tank filler cap and remove
it, and then wipe the attached dipstick
clean.
