Features

Convenience & Control

  • EASY ENGINE FLUSHING: A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.

Features

  • Prop Shaft Horsepower - 9.9 hp @ 5,500 rpm
  • Compression Ratio - 9.4:1
  • Recommended Fuel - Octane 87
  • C.A.R.B. Rating - 3-Star
  • Intake - 4
  • Spark Plug - BR6HS-10
  • Ethanol Blend Limit - 10% maximum
  • Compatible with Tiller Control
  • Standard Equipment - High thrust lower unit, tiller handle

Power & Performance

  • 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.
  • 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 standard on our T9.9 and is perfect for sailboats and pontoons. They can also be used on Yamaha Midrange outboards with 4.25 inch 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.

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.
  • CONSISTENT PERFORMANCE: Thermostatic Cooling Control helps provide proper engine temperature at all times for consistent performance and long, trouble-free engine life.
  • WET SUMP: The 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.
  • 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.
