Why Buy OEM

There are plenty of aftermarket oil tanks out there, but when you’re running a powerful TwoStroke engine, small differences matter. With OEM Mercury, you get components built to the exact standards your motor was designed around. No guesswork, no compatibility issues, no worrying whether a fitting or seal will fail at the wrong moment.

Choosing OEM means:

• A perfect match for Mercury TwoStroke oil systems
• Long-term durability in both freshwater and saltwater
• Confident installation without modifications
• Protection of engine performance, fuel efficiency, and reliability

If you want your outboard to last—and perform like it should—OEM is the only practical choice.
