WARNING
NOTE
To achieve accurate and consistent readings, engine temperatures must be measured at
the top of the cylinder head.
For the engine operating temperatures and RPM figures to be correct, the inlet water
temperature in the test tank must be 70° + 10°F (21° + 3°C).
The temperature indicating stick will appear dull and chalky when the surface marked is
below the rated temperature. When the surface exceeds the rated temperature, the mark
will appear liquid and glossy.
1.
Install the correct test propeller and place engine in test tank.
