adapter. The water reduces inner exhaust tem-
peratures and cools the propeller hub.
On 3.4 L models, propeller hub cooling water
flows through an internal passage of the inner
exhaust housing.
EMM
and Vapor Separator
Cooling
Cooling water is routed from the top of the cylinder
block to the inlet fitting of the
EMM
water cavity.
Cooling of the
EMM
helps to stabilize the tem-
peratures of internal components.
IMPORTANT:
Improper
EMM
cooling will acti-
vate service codes 25 and 29 and the Engine Mon-
itor warning system. Refer to the
EMM
Service
Code Chart
at the back of this manual for specific
service code information.
Cooling water from the
EMM
is routed to the water
inlet fitting of the vapor separator water cavity.
Cooling the vapor separator fuel chamber mini-
mizes fuel vaporization.
Cooling water from the vapor separator is routed
to the adapter/exhaust housing.
Engine Temperature
Check
IMPORTANT:
The engine temperatures listed
below are based on an intake water temperature of
70° ± 10°F (21° ± 3°C).
Install correct test propeller and place outboard in
a test tank or in the water. Start outboard and run
at 3000 RPM in FORWARD gear for at least five
minutes. Remember, running outboards at high
speeds in test tanks may disrupt water flow to
gearcase water intakes. Make sure the outboard
has adequate water flow.
Reduce speed to IDLE for five minutes. Check
IDLE operating temperature.
Increase speed to 5000 RPM and check tempera-
ture.
Check temperature on both sides of powerhead.
If engine temperature is not within range, trouble-
shoot cooling system.
If engine temperature tests within range, but the
engine monitor display indicates a “WATER
TEMP” warning, refer to

CAUTION
When servicing the propeller, always shift the
outboard to NEUTRAL, turn the key switch
OFF, and disconnect the Crankshaft Position
Sensor (CPS) to prevent accidental engine
starting.
