Yamaha® FourStroke Outboards
Built tough for reliable, long-lasting performance. From 2.5 to 350 horsepower.
Mercury's proven TwoStroke engines deliver easy starting, gutsy performance, and great all-round reliability. Across the range you’ll find an array of features that help keep your boating experiences more enjoyable and trouble-free. Features such as largest engine capacity displacement, giving you more low-end thrust, advanced carburettor design and fully-regulated, high output alternators powering all your marine electronics will ensure absolute boating excellence.
The ideal power companion.
The TwoStroke line includes the highest displacement engines in their horsepower classifications, plus they give outstanding power to weight ratios for best performance at all speeds.
V6 Grunt meets EFI refinement.
Electronic Fuel Injection (EFI) delivers fast acceleration and smooth, reliable performance, plus the added grunt of our 2 litre or 3 litre "big-block" engines.
Electric CDI ignition delivers high voltage for quick, sure starts and added fuel efficiency. Innovative sound attenuator helps absorb engine sounds before they can reach the ear, resulting in a quieter running engine on the TwoStroke 40 hp and higher models.
The simple TwoStroke design creates an engine that is less complex and lighter, with automatic low oil level warning for an added peace of mind.
