6)
Start the engine — run it at idle only and
flush it for at least five minutes. Check the
water pump indicator. A steady stream of wa-
ter must flow. If it does not, shut OFF the en-
gine and investigate. Refer to Engine
Overheating.
LOW OIL PRESSURE WARNING
Should crankcase oil pressure drop to a danger-
ously low level during engine operation, the low oil
pressure light will come on.

Low oil pressure light
1.
Water pump indicator
If the low oil pressure light is on, the engine speed
will not exceed 2000 RPM (FAST idle).
7)
Leave the outboard in vertical position long
enough to completely drain the powerhead.
If, during operation, your engine slows itself to fast
idle and will not exceed that pace, shut OFF the en-
gine.
Outboard — Not Running
If tilted, place the engine in vertical position.
1)
Remove the plug from the flushing port.
Check the oil level on the dipstick and add oil, if
needed. Refer to Crankcase Oil and Engine
Specifications.
Examine the oil fill cap and drain screw for evidence
of oil leakage and make sure they are tight.
If the dipstick shows the oil level is okay, leave the
engine upright and shut off for ten minutes, then
start it. If the engine still limits itself to about 2000
RPM, see your Dealer.

Reset - After oil pressure has been restored, oper-
ate the engine below 1500 RPM to reset the
warning system for normal operation.
1.
Flushing plug
The light will come on for a few seconds after the
engine starts. This verifies the warning system is
working.
2)
Install flushing device and garden hose with
threads matched to flushing port (thread:
0.75 – 11.5 NHR (ANSI)).
Start the water — keep pressure between 20
to 40 psi (140 to 300 kPa). Flush the engine
for five minutes.
Turn off the water, remove the hose and con-
nector (if used) and reinstall flushing plug.
Leave the outboard in vertical position long
enough to completely drain the powerhead.
If the light does not come on, stop the engine and
see your Dealer.
3)
If the light stays on, check the engine oil level and
add oil if necessary.
If the oil level is correct, see your Dealer.

5)
IMPORTANT: If you operate the engine with this
light on, severe engine damage can result. Do not
rely on the low oil pressure light to indicate the need
to add oil. Be sure to periodically check the engine
oil level. If the oil level is low, severe engine dam-
age can result.
