As Ethanol percentages increase in American’s fuel supply, boaters wonder if ethanol is safe for boat engines. Keith Holmes, President and Owner of CK Motorsports in Nunica, Michigan - a Certified Mercury Marine Racing Technician - explored, with the hope of finding more power, reliability, endurance and speed for offshore racing. Was it a good move? Are there problems with using Ethanol? We asked Keith some questions.
Q: What changes, to your boat and engines, happened to prepare for higher Ethanol use?
A: Not much. Besides tuning the engines at Sterling Performance for the proper air/fuel ratios for Ethanol fuel, everything on our boat is the same. We haven’t touched the fuel pumps, fuel lines or anything else on the engines. But remember, these are big engines with a tone of torque - no matter what the fuel - these size engines are prone to fail. That's why we refresh and maintain on a regular schedule. For recreational boaters, new products and systems are ready for install. These systems sense the ethanol mixture and adjust the air/fuel ratio automatically. Call CK Motorsports for more details.
