COOLING SYSTEM
ENGINE TEMPERATURE CHECK
If IDLE temperature is below specific operating
range, pinch off the water outlet hoses from pres-
sure relief valve to cylinder heads.
Use hose pinching pliers (acquired through local
tool source) to prevent hose damage.
Start the outboard and check IDLE operating tem-
perature using
Evinrude Diagnostics
software pro-
gram.
If IDLE temperature increases to specific operat-
ing range, 160°F ± 10°F (71°C ± 6°C), after pinch-
ing off hoses and eliminating water flow to the
cylinder heads, pressure relief valve is leaking.
Replace pressure relief valve.
If IDLE temperature is still below operating range
with hoses pinched off, inspect thermostats and
thermostat seals.
Thermostats
Remove thermostat cover(s) and inspect thermo-
stat(s).
Check position of thermostat seal and how ther-
mostat seals against cylinder head. Seal must be
properly fitted to flange of thermostat.
Check thermostat for cracks, heat damage, or
signs of corrosion. Check for proper operation.
Thermostat opens at 143°F (62°C).
