BoatUS embraces the need to diversify the country's energy sources. However, the organization is concerned that E.P.A. may put the "cart before the horse" by granting increased ethanol before understanding its operational effects on marine engines. A strong solvent, ethanol has been known to degrade fuel systems and lead to expensive repairs. "Last year, a record number of recreational boaters asked the E.P.A. to test marine engines before allowing up to 15 percent (E15) ethanol in gasoline," said BoatUS Vice President of Government Affairs Margaret Podlich. "While this testing has not been completed, we believe the E.P.A. is getting ready to announce their decision on increased ethanol in the next couple of weeks. We expect the agency will allow E15 for some engines and not others. In addition to the lack of scientific testing data, we suspect this will create different fuels with different prices, availability and add consumer confusion."
