4. Inspect the impeller blades to see if they are cracked, burnt, hard or deformed. Replace
the impeller if the blades are in this condition.
IMPORTANT: The circular groove formed by the impeller sealing bead should be dis-
regarded when inspecting cover and plate. The depth of the groove will not affect wa-
ter pump output.
5. Replace cover if plastic is melted from excessive heat (lack of water). Replace stainless
insert and/or face plate if grooves (other than impeller sealing bead groove) are more
than 0.010 in. (0.254 mm) deep.

IMPORTANT: It is recommended that all seals and gaskets be replaced (as a normal
repair procedure) to assure effective repair.
IMPORTANT: It is recommended that the water pump impeller be replaced whenever
the gearcase is removed for maintenance. However, if it is necessary to re-use the
impeller, DO NOT install in reverse to original rotation as premature impeller failure
will occur.
