John McKnight, director of environmental and safety compliance for the National Marine Manufacturers Association, and NMMA member Mark Riechers, director of regulatory development at Mercury Marine, are scheduled to testify Thursday and Friday at the California Air Resources Board in Sacramento.
Their testimony will highlight the problems associated with E15, as recently revealed in Department of Energy reports that were released in October, the NMMA said.
Testing showed damaging effects that E15 has on marine engines and noted that more testing is needed to further identify how E15 will affect engines and fuel systems under various conditions.
An additional concern is the possibility of a mandate for E10 fuel certification specification. Other biofuels are in development and could be available soon, which would make the mandate an unnecessary step, according to the association.
