The high-thrust T9.9 has been specifically designed to provide the extra grunt when you need to move big loads such as sailboats and heavy pontoons. Utilising a dual-thrust design the T9.9 produces twice the thrust of comparable two-strokes within the 2,000 to 3,000 RPM range, while delivering Yamaha’s the legendary reliability, durability, and efficiency that Yamaha Outboards are renown for.

The key mechanical difference between the T9.9 and the standard four-stroke platform is the use of a higher 2.92:1 gear ratio. This allows the T9.9 to spin a much larger propeller, generating more power to the water and resulting in less slippage. The T9.9 comes standard with Yamaha’s patented Dual Thrust propeller that provides maximum traction in both forward and reverse, by re-routing the exhaust in the opposite direction when in reverse. For additional on-water flexibility, the T9.9 is also available with a power tilt option.
