Since the federal government began replacing toxic MTBE with ethanol in fuel, boaters have faced troubling issues concerning ethanol's propensity to attract water, potentially damaging engines and fuel tanks. To better combat potential problems, Marine Development & Research Corp. developed E-Zorb Water Remover. E-Zorb disperses and emulsifies water and ethanol back into the fuel, allowing both to burn safely. One ounce of the product in 20 gallons of E-10 fuel effectively prevents condensation buildup. Cost for a 16-fluid-ounce bottle is $17.99. Call 516-546-1162 or visit www.mdramazon.com.
