TECHNICAL INFORMATION
Battery
For complete information, refer to the
battery manufacturer’s instructions.
Minimum Requirements
12V – 52Ah/5HR (65Ah/20HR)
(CCA420A)
• Be careful to avoid connecting the
battery in reverse polarity, as this
will damage the battery-charging
system in the outboard motor.
• Do not disconnect the battery
cables while the engine is running.
Disconnecting the cables while the
engine is running will damage the
outboard motor’s electrical system.
• Battery cable extension: Extending
the original battery cable will
cause the battery voltage to drop
due to the increased length of the
cable and number of connections.
This voltage drop may cause the
buzzer to sound momentarily when
engaging the starter motor and
may prevent the engine from
starting. If the engine starts and the
buzzer sounds momentarily, there
may be barely sufficient voltage
reaching the engine.
WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
Emission Control System
Information
Source of Emissions
The combustion process produces
carbon monoxide, oxides of nitrogen,
and hydrocarbons. Control of
hydrocarbons and oxides of nitrogen
is very important because, under
certain conditions, they react to form
photochemical smog when subjected
to sunlight. Carbon monoxide does
not react in the same way, but it is
toxic.
TOHATSU utilizes appropriate air/
fuel ratios and other emissions
control systems to reduce the
emissions of carbon monoxide,
oxides of nitrogen, and hydrocarbons.
Ignition Timing Control System
The system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
