Yamaha F25GMH
















Stylish. lighter and nearly a featherweight!!

Yamaha's innovative new F25 is around 25% lighter giving it a unique and unrivalled power-to-weight performance, It's not often an outboard is launched which truly leads its class by such a significant margin, but the new Yamaha F25 is just such an engine. A power to weight ratio unmatched by any competitive engine. By a distance!

Not only is the performance smoother and more impressive than ever, but there are many thoughtful features to make life on and off the water more enjoyable and relaxing. For example, portability and storage are easier, thanks not only to the new lighter weight, but also to the comfortable new carrying handle design and the two conveniently placed resting pads. Maintenance is simple too. An easy access hose connector on the lower cowling allows you to flush salt and dirt from the waterways without starting the engine - a quick, simple way to reduce corrosion and extend the 'life' and resale value of your engine. 

The incredibly light weight is not the only technical advance feature on the exciting new F25. Easy staring, even under the harshest conditions, is assured by the new battery-less electronic fuel injection (EFI) system and a choice of electric, manual or electric/manual staring options are now available.

The convenience of the new Electric start option brings full compatibility with Yamaha's advanced Digital Network System, which includes the availability of clear, stylish gauges that offer the driver a comprehensive selection of running data and engine performance information, as well as a more precise and relaxing level of control. The multi-function tiller handle is another attractive option for this engine. It has a forward-mounted shift control within easy reach of the driver and a large, strong tiller and throttle twist grip, for very comfortable steering, handling and manoeuvring. The integral VTS (Variable Trolling Speed) system not only provides a lower than normal idle speed, but also means you can control your trolling speed in simple 50 rpm steps - ideal for fishing. Standard on tiller handle models and an option on remote control models.
