The new 150 FourStroke is the ultimate 150hp EFI outboard engine that offers unprecedented world-class durability under all conditions and is light enough to deliver superb fuel efficiency and performance.

The 150 has picked up an innovation award from the International Boatbuilders Exhibition and Conference (IBEX) in Louisville, Kentucky. “Mercury Marine has found a way to trim 11kgs off their new 150 FourStroke, while helping to satisfy the growing need for superb fuel efficiency and performance,” said IBEX innovation awards judge Zuzana Procheska.

Available in both Mariner and Mercury brands, the 150 has a four-cylinder in-line configuration that easily creates power when used as either a single or twin application. It has more displacement than any other 150hp four-stroke engine and yet it delivers fuel efficiency at cruising speed that no other engine can beat.

The new 150 FourStroke is designed, built and tested to be the most reliable and durable 150hp four-stroke on the planet. The engine has endured severe cold climate field testing in applications off the west coast of Canada to commercial fishing in the warm waters of the Bahamas and the unprotected sea around Guadeloupe in the French West Indies. In fact, the 150 has encountered thousands of hours of harsh, real life testing applications that the average boat operator will never endure – all with excellent results.

The massive torque curve of the new 150 ensures that even the heaviest boats will plane quickly. This multi-use engine is the smallest 150 and the lightest four-stroke ever. It is the perfect option for boaters choosing to repower their boats, especially older models with transoms not designed to accommodate the weight of conventional four-strokes. With fewer parts than competitive products, the 150 FourStroke proves that technology can be used equally well to deliver durability and performance while simultaneously reducing package size and weight. “The new 150 FourStroke is class-leading in every respect but we particularly focused our attention on being a ‘stand-out’ in the areas that our customers told us we really matter to them; quality and reliability; smooth operation; a great torque curve; low weight and compact size; excellent fuel economy and easy maintenance,” said David Foulkes, vice president of engineering at Mercury. “We started our engineering efforts by listening hard to our customers and then we executed the most effective possible design to meet their needs.”

Boaters will find the new 150 exceptionally easy to maintain, durable and hassle-free in a size, weight and horsepower that will fit not only premium boats but mid and entry level vessels as well.

The new Mercury and Mariner 150 Fourstrokes will be available early 2012 in time for the boating season.

New 2012 MODEL YAMAHA F115.

Even lighter. Even more efficient. Even more versatile

Latest-generation F115 makes its debut at the

2102 PSP Southampton International Boat Show

A new version of the versatile and ultra-dependable F115 outboard will have its European launch at the 2011 PSP Southampton International Boat Show. The new F115 joins the Yamaha line-up for 2012 and looks sure to become even more popular and sought after than its predecessor - which has been a firm favourite with boat owners all over the world since its launch more than a decade ago.

The relentless model development programme at Yamaha has now made this iconic engine even lighter and more efficient. And like all the quiet and powerful Yamaha Four Strokes, the new F115 delivers a perfect blend of smooth, economical and reliable performance – promising people more relaxed and pleasurable boating than any other outboard. Whether the stern it graces belongs to a family cruiser, a sports boat or RIB, a fishing craft or a commercial workhorse.

Yamaha’s global reputation as the number one outboard manufacturer has been built on its heritage of constant innovation and the development of state-of-the-art technologies. The latest-generation F115 is yet another example of this philosophy in action.

Proven technology. Improved upon.

The F115 keeps its well proven DOHC, 1741cc, in-line 4-cylinder, 16-valve format, but by introducing a range of new parts and re-designing the fuel and air-intake systems, as well as the engine cowling, Yamaha have created an outboard that’s not only more efficient, but lighter too. Here’s how:

• New Intake Throttle – improves engine response. The new electronic single throttle valve replaces the original four valve set-up and works in combination with the ECM to increase fuel efficiency and deliver quicker acceleration and throttle response under all engine operating conditions.

• New Intake manifold – for maximum torque. A new long air intake manifold, fitted with a resonator, ensures exactly the right amount of air reaches the combustion chambers at precisely the right time to maximise mid-range torque. The new air intake system helps to make the new F115 3kg lighter without compromising its legendary durability and reliability.

• New cylinder head – improved performance. The combustion chambers and intake ports have been re-shaped too to increase efficiency. These improvements mean the F115 now delivers even stronger performance.

• New cowl – improves air flow and drainage. The new-shape cowling plays its part too, being designed to achieve more effective intake of air and even greater protection against the possibility of corrosion from water entering the casing.

• New Sensor – protects the engine. To complement the unmatched combustion efficiency, strong performance and excellent fuel economy of the multi-point EFI system, the latest F115 features an extra engine sensor. A new Knock sensor means the ECM (Engine Control Module) now receives engine information from no less than six separate sensors. This additional sensor detects any tendency of the engine to run less than perfectly, allowing the ECM to adjust the ignition timing with optimum precision.

• COMPATIBLE WITH Yamaha’s digital network system. With its comprehensive line-up of Digital Network Gauges. This revolution in command and control is every helmsman’s dream – precise, accurate information from the easy-to-read gauges and precise accurate control from the electronic engine control systems.

• Yamaah Customer Outboard Protection (Y-COP). Peace of mind comes standard on the F115. It’s the Yamaha Customer Outboard Protection system. Your Yamaha outboard is valuable and much sought after, sometimes by people you might not want to share it with. Y-COP’s simple push-button remote control immobilises your engine so that just like your car, it only starts when you want it to.
