Alcohol Modified Fuels

We do not recommend that you use alcohol-modified fuels in your MasterCraft boat because of the following side effects:

Moisture: Alcohol-blended fuels absorb and keep moisture. Moisture inside the fuel tank causes many engine problems.

Performance: Alcohol-blended fuels cause the engine to operate on a leaner fuel/air ratio and may cause hard starting, stalling and vapor lock. Engine damage may result.

Deterioration: Alcohol quickly deteriorates rubber and plastic components in the fuel system, causing more frequent inspection and replacement of parts. This increases the potential for fire and explosion due to fuel leakage. The new 2007 fuel system, however, is designed to withstand alcohol and MTBE fuel additives commonly found in the new oxygenated fuels. We still recommend fuels with as little alcohol as possible due to the moisture absorption problems. 

NOTE: Fuel additives and treatments, other than conditioners for moisture absorption and winter storage, are not recommended for use in MasterCraft Power engines.
