Emissions Compliance
Johnson 9.9/15 models are manufactured in
accordance with United States of America Envi-
ronmental 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.
WARNING
Do not attempt to run engine with any fuel
system component disconnected or
removed. Fuel leakage could contribute to
a fire or explosion.
