The following information is applicable only to boats sold in California.
Emission Control Warranty Information
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.
Operating Fuels and Lubricants
In order to keep your engine operating efficiently and to maintain the Emission Control System the
following requirements must be observed.
Fuel – Your engine was designed and certified to operate on the unleaded fuels listed below. Fuel ratings
must be based on the (R+M)/2 method and meet the specifications ASTM D4814 in the US. These fuels need
no additives for proper operation.

Lubricant – Indmar uses and recommends Pennzoil 15W40 Marine Oil for use in all of its engines. If
Pennzoil 15W40 Marine Oil is not available, any 15W40 motor oil meeting the API ratings of CF/SJ, CG-4,
CH-4 is acceptable. See Operator’s Manual for information regarding the use of synthetic oil.
Additives – The only additive that is recommended by Indmar for use in your engine is Sta-Bil

use of Sta-Bil
®

two weeks. See the Fuel section of your Operator’s Manual.
