Type of Gasoline To Use
Gasoline should meet the specifications ASTM D4814 in the United States and CGSB 3.5-92
in Canada.
If you operate your engine in a country other than the United States or Canada, unleaded fuels may be difficult
to locate. Using leaded fuels in your engine is not recommended as engine components will last longer using unleaded
fuel.
(Leaded fuel is not compatible with today’s engines.)
When a Boat Does Not Run For a While
The engine manufacturer recommends the use of a stabilizer such as Sta-Bil fuel stabilizer for boat users who
consume less than a tank of fuel every two weeks. Today’s fuels are more susceptible to degradation and the use of a
quality stabilizer will help ensure fewer problems for the occasional boater.
If your boat has not been used for more than 30 days during which fuel remained in the
tank (even stabilized fuel), the engine may run poorly until the “old” fuel is used up. Engine parts
and fuel injection components rendered inoperable or damaged from old and/or poor-quality
fuel will not be covered under warranty!
Always tighten the fuel plate cap completely with the cap key after refueling.
Fuels that are blended to contain methanol or wood alcohol are not to be used in MasterCraft engines. These fuels
can corrode some metal parts in your fuel system and engine. Damage caused by the use of unapproved fuels is not
covered by warranty.
Extended storage with fuel in the system can affect the fuel’s stability and may require system inspection and fuel
filter replacement when the unit is placed back into service.
Damage to the engine by use of low-quality gasoline or gasoline with an octane rating below the minimum level
listed will void the warranty on your boat.
Gasoline is extremely flammable and highly explosive under certain conditions. Always stop the engine and never
smoke or allow open flames or sparks within 50 feet of the fueling area when fueling.
Take care not to spill gasoline. If gasoline is spilled accidentally, wipe up all traces of it with dry rags immediately
and dispose of properly on shore.
Allowing the fuel level in the fuel tank to fall below one-quarter of a tank full may affect the reliability of the fuel
pump or result in damage to the fuel pump, which is not covered under warranty.
