FAQ's

What type of fuel can I use?*

2001 models and newer Mercury MerCruiser engines beginning with serial number 0M300000 will operate satisfactorily when using a major brand of unleaded fuel meeting the following specifications:

  • USA and Canada - Have a posted pump Octane Rating of 87 (R+M)/2 minimum. Premium gasoline [92 (R+M)/2 Octane] is also acceptable. Do not use leaded gasoline.
  • Outside USA and Canada - Have a posted pump Octane Rating of 90 RON minimum. Premium gasoline (98 RON) is also acceptable. If unleaded gasoline is not available, use a major brand of leaded gasoline.

Consult the Owner's Manual for more details.

Can I use reformulated or oxygenated fuels?*

Reformulated (oxygenated) gasolines are required in certain areas of the USA. The two types of "oxygenates" used in these fuels are alcohol (ethanol) or ether (MTBE or ETBE). These reformulated gasolines are acceptable for use in your MerCruiser engine. If the gasoline in your area contains either methanol (methyl alcohol) or ethanol, you should be aware of certain adverse effects that can occur. See your operation and maintenance manual for details.

Where do I take my boat for warranty repairs?

Olympic Boat Centers provides comprehensive warranty service for your new boat. Please make sure you read through the warranty policies for each product … the booklets are in the packet you receive at the time of delivery… and don’t hesitate to call us if you have a question.

When is my first service required?

The load on marine engines is much tougher than what is experienced with automotive engines. The break-in period is a critical time to insure trouble free operation. Mercury recommends that the oil, oil filter, and fuel filter are changed at 20 hours. After that, an annual service is sufficient (or 100 hours whichever is less).
