Check your oil. You’ve heard the expression “choose wisely.”

Never has this applied more than to the products you choose

to service, maintain and care for your Yamaha outboard. And

the oil and filters you use are perhaps most important of all.

• Why Yamalube

? Your Yamaha outboard is vastly different from your

automotive engine, and it operates in one of the harshest environments

imaginable. Yamalube provides specific protection other oils don’t, using a

proprietary blend of anti-wear additives, shear-stable polymers, corrosion inhibitors,

detergents, dispersants and viscosity index improvers. Yamalube is far superior to

automotive engine oils in its strength of protection, durability and corrosion resistance.

• Why Genuine Yamaha oil filters? Yamaha oil filters are manufactured specifically to protect

Yamaha engines, and use only the finest components available. From the quality of the

materials used to their high-quality construction, they simply out-perform aftermarket alternatives.

• Why FC-W

and TC-W3

oils? Whatever oil you choose, make sure it is the

correct type and viscosity and that it carries either the FC-W

(four stroke) or

TC-W3

(two stroke) label. These marks indicate oil that meets the minimum

standards of the National Marine Manufacturer’s Association (NMMA

) for

marine engines.
