ERVICE ONE (1) ENGINE AT A TIME.)
1. Run engines or generator for several minutes
to warm the oil and mix the sludge.

to the open position, in line with valve body.

direction of flow) and pump the old oil into

serviced, place the pump discharge hose into
a container of pre-measured fresh oil and
reverse the pump switch to pump the fresh oil
into the engine. NOTE: Fresh oil should be
at least 60° F (16½ C).

13. UNDERWATER GEAR
A. PROPELLERS
Propellers should be free of nicks, excessive
pitting and any distortions that alter them from
their original design. Badly damaged propellers
should be replaced, but those that are chipped,
bent or merely knocked out of shape can be
reconditioned by your marine dealer.
When doing extensive cruising, it is advisable
to carry extra propellers aboard.
