Rugged and smooth

Durable internal components, quality materials and precision engineering combine to provide smooth shifting and a long service life.

Power Trim XD

By moving the power trim pump inside the hull, we have virtually eliminated corrosion before it can start and made it easy to check or service the system while the boat is in the water. 

Performance
MercFusion paint system

From start to finish, Mercury drives are engineered tough, right down to a multi-part paint system that creates a durable outer seal against the elements.

Easy-check drive lube monitor

Routine drive lube checks are a breeze. You can check the level and quality of the lube from the engine compartment, and there is an audible warning that will alert you if the lube gets low.
