TECHNICAL INFORMATION
Tampering and Altering
Tampering is a violation of Federal
and California law.
Tampering with or altering the
emission control system may increase
emissions beyond the legal limit.
Among those acts that constitute
tampering are:
• Removal or alteration of any part
of the intake, fuel, or exhaust
systems.
• Alterations that would cause the
engine to operate outside its design
parameters.

Problems That May Affect
Emissions
If you are aware of any of the
following symptoms, have your
engine inspected and repaired by your
servicing dealer.
• Hard starting or stalling after
starting.
• Rough idle.
• Misfiring or backfiring under load.
• Afterburning (backfiring).
• Black exhaust smoke or high fuel
consumption.
Replacement Parts
The emission control systems on your
TOHATSU engine were designed,
built, and certified to conform with
EPA and California emission
regulations. We recommend the use
of TOHATSU Genuine parts
whenever you have maintenance
done. These original-design
replacement parts are manufactured
to the same standards as the original
parts, so you can be confident of their
performance. The use of replacement
parts that are not of the original
design and quality may impair the
effectiveness of your emission
control system.
A manufacturer of an aftermarket part
assumes the responsibility that the
part will not adversely affect
emission performance. The
manufacturer or rebuilder of the part
must certify that use of the part will
not result in a failure of the engine to
comply with emission regulations.
