When you need extra thrust and rock-solid control, the Yamaha T 25HP delivers. Designed for heavier loads and tough conditions, it combines high torque output with fuel-efficient performance — giving you the pushing power and dependability you can trust.
T 25HP
High Thrust. Maximum Control.
The Yamaha T 25HP is a High Thrust outboard built for demanding tasks. It features a special gear ratio (2.42:1) and a large-diameter low-pitch propeller that deliver massive thrust and precise control — making it ideal for heavier boats, pontoons, or working vessels. The engine’s 432cc twin-cylinder SOHC 4-stroke powerplant ensures strong torque, reliable acceleration, and excellent fuel economy. Yamaha’s PrimeStart™ and battery-less EFI system offer easy starting and consistent performance, even in challenging conditions.
With features like Variable Trolling RPM, Power Tilt, and an optional Multi-function Tiller Handle, the T 25HP delivers comfort and confidence. The high-output 12V 16A alternator keeps electronics running reliably, while Yamaha’s legendary YDC-30 aluminium alloy and Phaze Five™ anti-corrosion system ensure long-lasting durability. Available with both electric and manual start options, and in short or long shaft configurations, the T 25HP is the professional choice for power, performance, and peace of mind on the water.
