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.
