Measuring the fuel pressure
(high-pressure fuel line)
1. Remove the cap
1
.
2. Install the fuel pressure gauge onto the
pressure check valve.
3. Turn the engine start switch to ON, and
then measure the fuel pressure.
NOTE:
After the engine start switch is turned to ON,
the fuel pressure will decrease gradually.
4. Start the engine and warm it up for 5 min-
utes, and then measure the fuel pres-
sure.
NOTE:
The pressure regulator can be checked since
the fuel pressure (310 kPa [3.1 kg/cm
2
, 44
psi]), from when the engine switch is turned
to ON, decreases when the engine is idling.
Checking the fuel filter
1. Check the fuel filter element
1
for dirt
and residue and check the fuel filter cup
2
for foreign substances and cracks.
Clean with straight gasoline and replace
the cup if necessary.
NOTE:
Be sure not to spill any fuel when removing
the fuel filter cup.

Checking the engine oil
1. Place the outboard motor in an upright
position.
2. Remove the engine oil dipstick, wipe it
clean, and then insert it back into the oil
filler hole.
3. Remove the dipstick again to check the
oil level, and the oil for discoloration and
its viscosity.
NOTE:
• Change the oil if it appears milky or dirty.
• If the engine oil is above the maximum level
mark (H), drain sufficient oil until the level is
between (H) and (L).
• If the engine oil is below the minimum level
mark (L), add sufficient oil until the level is
between (H) and (L).
