The Outboard Wizard


With the increased distribution of ethanol (alcohol) blended fuels, many outboard boat owners are asking:

What type of fuel does my outboard engine manufacturer recommend?

Check your boat motor's owners' and service manual first.  Older engines and some 2 and 4 Stroke engines are especially at risk from damage due to the use of alcohol (ethanol) blended fuels.

Using the correct type and blend of gas in your outboard engine is critical to your engine's performance and life expectancy.

Since most states in the U.S. are switching to 10 % ethanol alcohol blended fuels, you may need to update and replace parts in your engine,  to protect your outboard motor from the potential harmful effects of ethanol on outboard engine components.

Be aware of the symptoms and effects on your engine that will occur when using the wrong type of fuel (gas).  Often the first symptom of using fuel that is bad for your marine engine will be stalling  when accelerating with WOT.

Using the wrong type of fuel will cause symptoms ranging from frequent stalling to engine death.

Simple actions now, will protect you from costly repairs later.
