Home » Yamaha Outboards » High Thrust 4-Strokes » High Thrust Four Stroke T9.9
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.
The FT9.9 utilises a torque-rich four-valve, twin-cylinder, single overhead camshaft marine engine, which delivers impressive torque from low-to-mid speed ranges, for quick response and smooth operation.
Yamaha's large-diameter, low-pitch dual-thrust propellers are designed to give instant power in both forward and reverse, by redirecting exhaust gases way from the propeller, reducing reverse ventilation and generating more power to the water. This increases forward thrust by up to 60% and reverse thrust by up to 70%.
Simply connect a hose to the easy access connector to flush salt and dirt from the outboard without having to run the engine. Flushing the engine after each usage reduces corrosion and extends the engines life.
A 12-Volt 6-Amp high-output alternator ensures that power is always available to start the engine, even after long periods of idling or running at low revs. This not only provides extra starting power, but delivers sufficient power to run the wide array of on-board electronic devices used in modern boating.
The FT9.9 utilises a lower gear case design, featuring a high gear ratio of 2.92:1. The gears are specially hardened to withstand the toughest working conditions - for long-term durability.
A higher gear ratio of 2.92:1 allows the FT9.9 to operate a large diameter propeller. This improved capacity enables the outboard to push greater volumes of water for increased thrust.
The FT9.9 features a one-piece outer cowling design, with an intake drain system to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages traps and drains water before it enters the engine’s intake, for maximum reliability.
Yamaha’s push-button control makes tilting the engine quick, smooth and effortless.
Exclusive to Yamaha, Prime Start makes starting a Yamaha outboard as easy as starting a car. It allows the engine to be started cold by automatically controlling the engine ‘warming up’ process - eliminating the need for a conventional choke. With Prime Start you no longer need to ‘warm up’ your engine by revving it in neutral.
Yamaha engines are known for their durability and high re-sale value. Part of this lies in the anti-corrosion protection. A unique YDC-30 aluminium alloy protects the engine's exterior parts, while a zinc coating, high-quality stainless steel components and 5-stage exterior paint coating, offers long-lasting protection - inside and out.
Yamaha offers a range of rigging options to suit every boat. Check out the full suite of controls, gauges, switches, props and other technologies, plus outboard performance data.
