CARBURETOR
Emissions Compliance
Johnson 9.9/15 models for model year 2004 are
manufactured
in
accordance with United States
of America Environmental Protection Agency
(EPA)
standards for emissions.
These models are equipped with tamper resis-
tant carburetors. When servicing,
DO
NOT sub-
stitute any part of the carburetor with non-tamper
resistant parts.
In
addition, carburetor fuel mixture adjustments
MUST NOT be altered
from
original factory cali-
brations beyond the limits allowed by the tamper
resistant device.
Changes to the original design or adjustment lim-
its of the outboard that effect emissions are a vio-
lation of federal
law,
and become the
responsibility of the servicing technician and/or
the owner.
When servicing the carburetors, it is very impor-
tant that the procedures
in
this section are fol-
lowed EXACTLY to ensure compliance with
emissions standards.
