COOLING SYSTEM
ENGINE TEMPERATURE CHECK
10
Software Method
Use
Evinrude Diagnostics
software to read tem-
perature displays.
Typical temperature displays at IDLE speed
should be 160°F ± 10°F (71°C ± 6°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
temperature.
Measure temperature at the top of cylinder block,
next to the thermostat housing and cylinder head.
Check temperature on both sides of powerhead.
Typical temperatures observed at IDLE speed
with pyrometer should be 143°F ± 15°F (62°C ±
8°C)
IMPORTANT:
If you get low or inaccurate read-
ings with a digital pyrometer, coat the probe loca-
tion with
Thermal Joint Compound
, P/N 322170.
Idle Operating Temperature
Troubleshooting (Below Range)
If engine IDLE temperature is below operating
range 160°F ± 10°F (71°C ± 6°C), check thermo-
stat and pressure relief valve operation.
Pressure Relief Valve
The pressure relief valve should be closed at
IDLE speed. Water should not flow past the
plunger and seal.
If IDLE temperature increases to specific operat-
ing range, pressure relief valve and thermostats
are functioning properly.
