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.
