ENGINE
The following information is applicable only to boats sold
The inboard engine in your boat includes the Indmar
Emission Control System identified as MFI or TBI or
EM. Refer to the identification sticker on your engine to
determine which emission control system was used on
your engine. The fuel and ignition systems on your
engine meet the stringent requirements set forth by
the California Air Resources Board (CARB). Indmar also
uses Sierra brand anti-freeze in the closed cooling
system of your engine to reduce the environmental
impact in the event that anti-freeze is expelled from
the engine.
Your Indmar-manufactured engine has a special
environmental label required by the California Air
Resources Board (CARB). The label has 1, 2, 3 or 4
stars. A hangtag, provided with your inboard engine,
describes the meaning of the star system.
