| Note: These Mercury outboards have 4-stroke engines and, like virtually all 4-stroke engines, depend on oil in their crankcases for lubrication. To prevent the oil from leaking during transport, the engines are not shipped with oil in their crankcases. You must put the correct amount and grade of oil in the crankcase prior to the first use or you will cause extensive damage to your engine, which is not covered by your engine’s warranty. Please read the owner’s manual for more information. |
