When you need a little extra muscle

High Thrust

Extra Muscle

High Thrust Four Strokes

Mechanical or Tiller: 60 hp, 50 hp, 9.9 hp Mechanical: 25 hp

Yamaha’s 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, an all-new 25 and a 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.

Owners Manuals

Sporty New Look

Because the Yamaha High Thrust T9.9 is such a popular kicker motor for the V MAX SHO^®, it’s now available with an optional, V MAX SHO-inspired sport cowl. This creates a consistent look between your outboards—and throws a whole lot of attitude on the back of your boat.

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 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. Yamaha’s 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.

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

Yamaha’s 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.

High Thrust 25 hp

Our 432-cc 25-hp High Thrust outboard delivers the power and grip with exceptional efficiency. This newly redesigned outboard has the best power-to-weight ratio of all high-thrust 25 horsepower outboards. With the new design comes a no-battery-required Electronic Fuel Injection as well as electric and manual start on all models. The new 25hp High Thrust model comes in both 20 and 25 inch shaft lengths for a wider range of applications. Also included, Variable Trolling RPM Switch (VTS^®) which allows slower trolling than standard in-gear idle for better fishing.
