Choosing the Right Oil for Your Yamaha or Mercury Outboard

Choosing oil for your outboard involves more than simply selecting a familiar viscosity. Yamaha and Mercury engines have specific lubrication requirements, and using products that match your engine specifications is an important part of routine maintenance.

Start With Your Engine Specifications

Before purchasing oil, identify your outboard model and review the manufacturer’s recommendations. Oil type, viscosity and required quantity can vary depending on the engine.

Your owner’s manual provides specifications applicable to your particular outboard. Following those recommendations takes the guesswork out of selecting maintenance products.

Don’t Forget the Oil Filter

An oil change may involve more than replacing the oil itself. Depending on the required service, you may also need an appropriate oil filter and other maintenance components.

Oil change kits can make routine service more convenient by grouping commonly required products together. However, you should still verify that the kit corresponds to your specific engine before purchasing it.
