Yamaha's 4 Stroke Midrange Series

And Yamaha has the audacity to call them lightweights. Considering the dramatic increase in fuel efficiency, we guess you could call your Yamaha Four Stroke a long-range investment. Along with the extra fuel savings comes extra convenience and reliability. There's no mixing oil with gas. The Top-Mounted Flywheel keeps sensitive electrical components out of the water. Yamaha Four Strokes range all the way from our compact 4 hp portable to the powerful F115.

The Yamaha F115 takes four stroke technology to a whole new level. The unique Long-Track Induction System uses four throttle valves, along with our Multi-Port Precision Electronic Fuel Injection, to deliver the precise fuel/air ratio to each individual cylinder. The result? Instant starts, quick acceleration, superior performance and outstanding fuel economy. It's definitely a Yamaha.

• Microcomputer Ignition adjusts ignition timing to maintain optimum engine performance, economy and durability under all conditions.
   
• Dual Overhead Cam Design compared to conventional single overhead design feature less moving parts for greater reliability.
   
• The Multi-Function Tiller handle provides convenient fingertip control of starting, shifting, steering and throttle.
   
• The Front-Mounted Freshwater Flushing Device makes it easy to completely flush the motor at the slip, or at home.

2001 Four Stroke - Portable

Yamaha Four Strokes even come in sporty, compact portables.

We wanted to make sure that even the smallest boats could have the benefits of a Yamaha Four Stroke. They start as small as our F4, recent winner of a prestigious world record for gas mileage þ covering an unprecedented 67.27 miles on a single gallon of gas. For 2001 we've added a new F6 and F8, creating a complete line-up of compact and lightweight portables. Like all Yamaha Four Strokes, you can count on these portable powerhouses to deliver smooth, reliable, clean, quiet and fuel-efficient performance day in and day out.

Yamaha Four Strokes are packed with high-powered technology. Our Crossfire Valve Fuel Charging maximizes combustion for smooth running and provides outstanding low-throttle characteristics for trolling. Maintenance-free CD Ignition provides instantaneous starts and longer plug life. Thermostatic Cooling keeps the engine at the proper temperature at all times. The Shallow Water Drive lets you head for skinny water with less danger of damaging your prop. And most Yamaha Four Strokes feature our exclusive Freshwater Flushing Device.
