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.
CAUTION
When servicing the propeller, always shift
the outboard to NEUTRAL, turn the key
switch OFF, and twist and remove all
spark plug leads so the engine cannot be
started accidentally.
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 WATER TEMP/ HOT Cir-
cuit Test on p. 108.

ENGINE TEMPERATURE CHECK

Software Method

Use Evinrude Diagnostics software to read tem-
perature displays.
Engine Monitor Screen
Typical temperature displays at IDLE speed
should be 160°F ± 20°F (71°C ± 11°C).
Typical temperature displays at WOT speed
should be 120°F ± 20°F (50°C ± 11°C).
Operating temperature must not exceed 194°F
(90°C).

Pyrometer Method

Use a Temperature Gun, P/N 772018, or a digital
pyrometer to measure the outboard's operating
temperatures.
Measure temperature of the thermostat housing at
the top of each cylinder head.
