Special gear ratios for higher thrust
The FT engines are purpose designed to deliver greater thrust and torque than a conventional engine and their special gear ratios help prevent cavitation and prop slippage. They work in combination with other unique features to provide the ideal power source for boats where load-hauling capability is more important than high speed.
Large multi-function tiller handle option
This great option brings all the engine controls neatly within reach of the driver and provides an even larger tiller for comfortable steering, handling and manoeuvring. Whether pottering around the marina or flying along at the higher speeds this remarkable engine can deliver, it makes the FT25 even more enjoyable to own and use.
Dual-thrust props for maximum power in Forward & Reverse
The special propellers fitted to the FT Models are not only of a larger than normal diameter, but have low pitch blades, designed to maximise thrust in both Forward and - by re-directing the exhaust flow - in Reverse too. This gives greater manoeuvrability, which is especially helpful when handling a heavier boat.
PrimeStart™ - as easy as starting your car
Yes, starting your outboard engine is now as easy as starting a car – even from cold. Exclusive to Yamaha, the legendary PrimeStart™ system ensures that the engine fires first time, every time you engage either the Electric or Manual Start.
Great performance with quiet, low-vibration running
An acceleration pump combines with a long intake to increase efficiency at low to medium speeds, delivering the power you need, when you need it most. The FT25 also has a counter balancer and long span mounting, which combine to limit vibrations felt in the boat and a special labyrinth exhaust to help decrease noise levels.
Never get left short of electrical power. A High-output alternator is a standard feature on our FT series of outboard engines, ensuring that power is always available to start the engine – even after prolonged periods of idling or when you've been running at low revs and using multiple accessories.
Extra convenience and driving comfort
You'll find the FT25 very easy to control and comfortable to drive, thanks to its many features - from the front-mounted shift lever and single-lever steering friction adjuster to the decompression device for smooth, easy starting. The optional multi-function tiller handle is yet another reason to choose this tough, reliable engine.
