On Wednesday, Mr. David Hilbert testified before Congress on behalf of NMMA to address concerns about E15 and marine engines. Mr. Hilbert, thermodynamic development engineer for Mercury Marine, a division of the Brunswick Corporation, participated in a Congressional hearing before the Subcommittee on Energy and Environment of the House Committee on Science, Space and Technology. The subcommittee invited a number of specialists to testify on E15 and its effects. Mr. Hilbert led the research on E15 and its effects on marine engines as reported by the Department of Energy in reports released in late October.
Mr. Hilbert’s testimony highlighted the 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. Mercury’s testing showed significant problems with outboard engines, including severe damage to engine components and an increase in exhaust emissions, reinforcing the recreational boating industry’s concern that E15 is not a suitable fuel for marine engines.
The Subcommittee heard testimony from representatives of the EPA, the American Petroleum Institute, Gevo, the Energy Biosciences Institute, the University of Wyoming Institute of Environment and Natural Resources and the National Petrochemical & Refiners Association. Subcommittee Chairman Andy Harris (R-MD), received David’s testimony favorably and the committee members had no questions for Mr. Hilbert after the research was presented. The testimony and accompanying photos will be printed in the official record of the hearing.
