High tech engine range from Yamaha

Lighter, Faster, Stronger.

These three words are generating excitement in the marine industry following the release of a new generation of Yamaha outboards. Dubbed “Game Changers” in the US market, these engines have been built using innovative new material and processes bringing a fresh approach to the design of this next generation of outboards. The game has been changed forever

Yamaha’s New V6 Four Strokes

The F300 - F250 - F225 are based on a newly-developed 4.2L 60 degree V6 engine. A double overhead camshaft design matched with variable camshaft timing produces excellent performance and fuel economy.

This new generation of V6 outboards has been developed to continue Yamaha’s reputation for reliable and powerful offshore engines while stepping up performance and innovation to a new level.

By using a highly-advanced plasma fusion process on the cylinder walls, Yamaha’s new V6 Offshore outboards now have cylinder walls that are 60% harder than steel. The result is larger cylinder bores for increased displacement, resulting in more power and torque without increasing outer cylinder dimensions.

It also means lighter weight. In fact all three new models in this range weigh less than Yamaha’s current 3.3 litre F225, far lighter than any competing four stroke model. Weight is now comparable to direct injected two strokes but the new range offers substantially larger capacity. The plasma fused cylinders also result in better cooling and the “micro-textured” cylinder walls help decrease friction and further increase performance and enhance reliability.

More grunt from larger capacity means a lower 1.75:1 gear ratio has been used on these engines. This allows the offshore V6s to spin a larger propeller for better hole-shot performance while the variable camshaft timing provides crisp acceleration and great fuel economy right through the rpm range.

The F300, F250 and F225 utilise the state of the art “drive by wire” control systems ensuring smooth throttle operation and responsive performance while also providing secure and reliable shifting. The engines also feature a patented shift dampening device that eliminates the noise that sometimes occurs when engines are shifted in and out of gear.

The new Yamaha V6s are compatible with brand new instrumentation in the form of a five inch colour LCD screen with a range of display options for the outboard and the boat. The display has the ability to connect and display information from up to three engines.

Yamaha outboards are available through a New Zealand-wide network of authorised Yamaha outboard dealers. All Yamaha 4-stroke outboards are supported with a full 4-year manufacturer’s warranty and all 2-stroke outboards are backed by a 3-year warranty – conditions apply.

This brand new range of Outboards in 225, 250 and 300 horsepower will be available from June 2010 in “X” 25 inch and “U” 30 inch shaft lengths. They will also be available in “L” Counter Rotation versions for multi Outboard installations.
