TESTING AND ADJUSTING

DYNAMOMETER TEST CAUTION

(Marine Engines)

To prevent possible damage to an engine while

testing on a dynamometer, the water temperature

regulators must be installed and coolant connections

made as shown.

REMOVING END CLEARANCE

Remove the water pump. Measure the thickness

of the wax that is between the vanes and the

front Rover. When the last bolts are removed, be

careful not to hit the clay or wax. The impeller

clearance (2) is .011 to .035 in. (0.28 to 0.89

mm).
