11. MAINTENANCE
Safety Precautions
l
Make sure the engine is off before
you begin any maintenance or
repairs. This will eliminate several
potential hazards:
-Carbon monoxide poisoning from
engine exhaust.
Be sure there is adequate ventila-
tion whenever you operate the
engine.
- Bums from hot parts.
Let the engine cool before touch-
ing.
-Injury from moving parts.
Do not run the engine unless
instructed to do so.
l
Read the instructions before you
begin, and make sure you have the
tools and skills required.
l
To reduce the possibility of fire or
explosion, be careful when working
around gasoline. Use only a nonflam-
mable solvent, not gasoline to clean
parts. Keep cigarettes, sparks, and
flames away from all fuel-related
parts.
Remember that an authorized Honda
Marine dealer knows your outboard
motor best and is fully equipped to
maintain and repair it.
To ensure the best quality and
reliability, use only new, genuine
Honda parts or their equivalents for
repair and replacement.
EMISSION CONTROL SYSTEM
INFORMATION
Source of Emissions
The combustion process produces
carbon monoxide, oxides of nitrogen,
and hydrocarbons. Control of hydrocar-
bons and oxides of nitrogen is very
important because, under certain
conditions, they react to form photo-
chemical smog when subjected to
sunlight.
Honda utilizes lean carburetor settings
and other systems to reduce the emissions
of oxides of nitrogen and hydrocarbons.
