This legendary twin cylinder, 4-stroke portable is now around 25% lighter! Open the throttle of our brand new 25hp and you’ll immediately feel the effect of Yamaha’s innovative technologies at work, delivering big-engine features with unique power-to-weight performance and outstanding economy.

Meet our new portable. Even lighter. Even tougher.

The specification now includes two resting pads (side and rear), improved carry handles, battery-less EFI and full compatibility with our Digital Network Gauges.

With its single-lever steering friction adjustment, new wide-span motor mount, high-output alternator and options of Variable Trolling Speed, Y-COP Security and Wide Range Power Trim & Tilt, the 25hp is the natural choice.

When you want power and handling, T models are the perfect answer. Ideal for sailing, fishing and working boats, these high-thrust, high-torque engines set new standards of performance, with minimal noise and vibration – and maximum fuel economy.

The T 25hp – another of our High-Thrust workhorses

T models use Yamaha’s patented Dual-Thrust propeller to provide full thrust in Forward and Reverse – making light work of manoeuvring a heavy boat.

Offering all the same technical features and advantages of the world-renowned and intensively proven 25hp – but more – this T version is like a powerful workhorse – designed never to let you down. Naturally, brilliant fuel economy and easy handling come as standard.
