Notes
Your outboard motor should receive
careful, and complete inspection at
300 hours. This is the best time for
major maintenance procedures to be
carried out.
Replacing engine oil
Engine oil mixed with dust or water
will dramatically shorten the life of the
engine.
To change engine oil:
① Stop the engine and set it in a tilted
position.
② Remove the top cowl and oil filler
cap. Allow it to cool.
③ Turn the steering on the outboard
motor so that the drain hole is fac-
ing downward.
④ Put a oil drain pan under the oil
drain screw.
⑤ Remove the oil drain screw and
completely drain oil from the en-
gine.
⑥ Tighten the oil drain screw.
⑦Reset the engine in a vertical posi-
tion.
⑧ Repeat ⑤ and ⑥ .
⑨ Fill the engine through filler port
with recommended oil (see chart
below) to the upper dipstick mark.
⑩ Tighten the oil filler cap.

SF, SG, SH, SJ, SL, or SM. Select
the appropriate viscosity, based on
atmospheric temperature, from the
chart below.
