TIP:
If a torque-wrench is not available when you
are fitting a spark plug, a good estimate of the
correct torque is 1/4 to 1/2 a turn past finger-
tight. Have the spark plug adjusted to the cor-
rect torque as soon as possible with a torque-
wrench.

Changing engine oil

Change the engine oil several minutes after
the engine has been stopped, so that the oil is
still warm, but not hot.

Be sure the outboard motor is securely
fastened to the transom or a stable stand.
NOTICE

Change the engine oil after the first 20
hours of operation or 3 months, and every
100 hours or at 1-year intervals thereafter.

sition (not tilted). NOTICE: If the out-
board motor is not level, the oil level
indicated on the oil dipstick may not
be accurate.
