2019 Yamaha T9.9 - 25 in. Shaft


Yamahas High Thrust four strokes, are built for jobs that call for more muscle”like pushing a heavy pontoon, adding extra kick to a multi-species boat or maneuvering a sailboat through a crowded marina. Available in 60, 50, 25 and 9.9 horsepower, their larger lower units and higher gear ratios produce substantially more thrust than conventional outboards of the same horsepower using standard propellers. In fact, when paired with our Dual Thrust propellers, (optional on T60/T50 and standard on our T25 and T9.9) Yamaha High Thrusts produce up to 60 percent more forward thrust and up to 70 percent more thrust in reverse.

Power & Performance
More Thrust: The Higher Gear Ratio on Yamahas High Thrust outboards make these powerhouses ideal for heavy pontoons and other applications that require an extra measure of muscle.
Max Muscle: Increase thrust up to 60 percent in forward and 70 percent in reverse with a large-diameter, low-pitch Dual Thrust propeller. They're optional on our High Thrust T50 and T60, and standard on our T25 and T9.9, and are perfect for sailboats and pontoons. They can also be used on Yamaha Midrange outboards with 4.25" K gearcases.
Optimum Performance: Microcomputer Ignition adjusts timing to maintain optimum engine performance, economy and power under all conditions.
Single Overhead Camshaft: A Single Overhead Camshaft (SOHC) design creates a compact, lightweight, space-saving design.
Fuel Economy: Precision Multi-Point Electronic Fuel Injection on the T60 and T50 delivers the exact amount of fuel needed for optimum performance and efficiency. Yamahas EFI optimizes fuel atomization, further enhancing fuel economy.

Reliability & Durability
Solid and Dependable: Incoming air is routed through an Air Intake Labyrinth System that traps and drains water before it enters the engine's intake for maximum reliability.
Corrosion Protection: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha High Thrust four-stroke engines.
Wet Sump: The T50, T60, T25 and T9.9 all feature a pressurized oil delivery system that incorporates a compact and durable oil pump to keep all of the moving parts of their SOHC systems lubricated and running smoothly for maximum reliability.
Consistent Performance: Thermostatic Cooling Control helps provide proper engine temperature at all times for consistent performance and long, trouble-free engine life.

Convenience & Control
Gauge Compatibility: Optional Command Link gauges provide real-time outboard performance, boat systems and environmental data at your fingertips. Streamlines displays available in square or round style for single- or multi-engine applications.
Ergonomic Control: Yamahas award-winning, Multi-Function Tiller Handle (optional on T60/T50) features an ergonomic design for easy shifting , better grip and less rotation from idle to wide-open throttle. This reduces operator fatigue for a full day of enjoyable boating. Truly multi-function, it control features include throttle, throttle friction control, shift lever, key switch, stop switch and a Power Trim & Tilt switch.
Easy Engine Flushing: A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
