Dual Thrust Propellers

Max Muscle

Large-diameter, low-pitch Dual Thrust™ Propellers (optional on T50/T60 and standard on T25/T9.9) are designed specifically to harness the power of our High Thrust outboards. They redirect exhaust flow away from the propeller, reducing ventilation and increasing thrust up to 60% in forward and 70% in reverse.

Higher Gear Ratio

More Thrust

The Higher Gear Ratio on Yamaha’s High Thrust outboards make these powerhouses ideal for heavy pontoons and other applications that require an extra measure of muscle.

Microcomputer Ignition

Maximum Overall Performance

Microcomputer Ignition adjusts timing to maintain optimum engine performance, economy and power under all conditions. 

Thermostatic Cooling Control

Consistent Performance

Thermostatic Cooling Control helps provide proper engine temperature at all times for consistent performance and long, trouble-free engine life. 

C.A.R.B. Three-Star Rated

Ultra-Low Emissions

Yamaha high thrust four strokes are California Air Resources Board (C.A.R.B.) Three-Star Rated for Ultra-Low Emissions and meet all federal EPA requirements.


Five-layer corrosion barrier

Anti-Corrosive Barrier

Yamaha’s proprietary ACP-221 Paint Process provides an extra-tough, five-layer barrier against corrosion. It’s a key component of our renowned Ultimate Corrosion Protection System (UCP-II™), which is standard on all Yamaha high thrust outboards. 

Corrosion-resistant alloy

Ultimate Corrosion Protection

Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha portable four-stroke engines.

A Freshwater Flush Device allows you to flush the engine without starting it, for maximum convenience, durability and engine life. 

Four Stroke Three-Year Warranty

Warranty Protection

All Yamaha four strokes are protected by our Three-Year Limited Warranty for pleasure use. Beyond that, Yamaha Extended Service (Y.E.S.) plans are available, for continued coverage after your three-year factory warranty expires.


Multi-Function Tiller Handle

Ergonomic Control

Yamaha’s award-winning, Multi-Function Tiller Handle (optional on T60/T50/T25) features an ergonomic design that reduces operator fatigue, allowing you to spend more time on the water. Its smart design places the power trim and tilt switch conveniently above the throttle, which features a large rubber twist grip that requires less rotation to go from idle to wide-open throttle (90°). (The T9.9 also has tiller models available.)
