Maintenance
Periodic maintenance
WARNING
These procedures require mechanical
skills, tools, and supplies.
The procedures involve disassembling
the
motor and exposing dangerous parts.
To
reduce the risk of injury from moving,
hot,
or electrical parts:
•
Turn off the engine and keep engine
shut-off cord (lanyard) with you when you
perform maintenance unless otherwise
specified.
•
Allow the engine to cool before handling
hot parts or fluids.
•
Always completely reassemble the
motor before operation.
Maintenance, replacement, or repair of the
emission control devices and systems
may
be performed by any marine engine
repair
establishment or individual.
Replacement parts
Any part of inferior quality
may malfunction,
and the resulting loss of
control could endanger
the operator and passengers.

Maintenance interval guidelines
The service intervals provided in the Mainte-
nance Chart were developed based upon
"typical" use that includes operating at varied
speeds, with sufficient time for engine warm
up
and cool-down, a medium to light load, and
an
average cruising speed near the 3000 to
4000
rpm range. As with any engine, however, if your
normal operating conditions are different, you
should consider service more
often than
shown, especially how often you
change your
engine and gear oil. Examples
might include
extended wide-open-throttle use or long periods
of trolling or idling, carrying heavy loads, or
frequent starting and stopping or shifting. More
frequent maintenance
will often pay off many
times over in increased
engine life and greater
owner satisfaction.
