RECOMMEND FUELS

FOR USE INDMAR MARINE ENGINES

NOTE:  I If the recommended fuel is not available, your engine may operate on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87. A noticeable reduction in performance, drivability and fuel economy will result.  It is not recommended to operate under heavy usage with less than the recommended octane for your engine.

Poor quality, contaminated or old gasoline can cause symptoms such as poor drivability, hard starting, rough running or overall poor performance.  If you experience these symptoms, first try fresh fuel from another station.

Indmar does not endorse or recommend the use of additives sold as “Octane Booster”, “Octane Enhancer” or any other product claiming to increase or restore the octane or quality of gasoline.  These additives can contain chemicals that may alter the emissions of the engine or cause damage to the emissions components.   REFER TO YOUR OPERATORS MANUAL FOR MORE DETAILS

Biobutanol-Blended Gasoline

Engines covered by this manual have been approved by Indmar for operation on gasoline blended with 16% Biobutanol, or Bu16.  Use of Biobutanol will not void the warranty of Indmar gasoline engines.

Indmar and the National Marine Manufacturers Association encourage the use of Biobutanol in marine engines.

Biobutanol (either isobutanol or n-butanol) is created from biomass and is blended with gasoline to help meet renewable fuel mandates and clean air standards. Bu16 contains a higher percentage (16%) of renewable fuels than traditional E10 gasoline (10%), without sacrificing engine performance or reliability.

Bu16 can be mixed with any E10 or other approved fuel already in the boat’s fuel tank(s).

Biobutanol is chemically different from ethanol and does not have ethanol’s negative characteristics when blended in fuel. The Bu16 fuel blend does not absorb water like E10; the phase separation common in E10 fuel does not occur in Bu16. Isobutanol is not a corrosive agent (ethanol is highly corrosive) and will not damage fuel system parts. These characteristics, combined with a significantly higher energy content, make Bu16 fuel ideal for marine engines.
