In-Water Gear Lube Servicing – The draining and replacement of the lower unit gear lubricant can occur while the boat is docked on the water, making the servicing of larger boats easier, quicker and cheaper.

Multi-Part Cowling System – By designing the cowling in separate, easily removable parts – getting to specific sections of the outboard for servicing is now quicker and easier. This new cowling design also makes it possible to service larger boats while they are docked on the water.

Yamaha Outboard Tech –Yamaha offers a range of rigging options to suit every boat. Check out the full suite of controls, gauges, switches, props and other technologies, plus outboard performance data.

F425 Performance Data Reports –We take out the guess work in buying a new outboard, by rigorously testing our engines on Australia’s most popular boat brands. See how the F425 performs for acceleration, fuel economy and top-end speed on your favourite boat.

Redesigned Lower Unit –The hydrodynamically designed, oversized gear case enables higher maximum speeds and greater stability when turning. The high quality marine grade stainless steel components and hardened gears have been designed to handle extreme loads and highly corrosive marine environments.

5559CC V8 Engine – The massive 5.6 Litre, 32 valve, direct fuel-injection, four-stroke engine delivers enough power to push large and heavy offshore boats. The self-tensioning chain immersed in an oil bath ensures quiet, maintenance free and consistent valve timing.

High Output Alternator – This powerful three winding, three phase charging system generates up to 90 Amps of electrical power. Additionally, 55 Amps of power can be generated while idling. This high output alternator enables a stable supply of power for running a wide array of electrical devices.

Integrated Electric Steering – This industry first ‘steer-by-wire’ system uses an electric motor to directly move and secure the outboard, without any hydraulics or electric pump. This delivers very fast, precise, leak free and maintenance-free steering – that uses less power and is packaged in a clean rigging set-up.

Fully Integrated Power System –The fully integrated power system creates a truly effortless boating experience. The system combines integrated electric steering, ‘drive-by-wire’ throttle controls, Yamaha’s premium CL7 multifunction display and Helm Master joystick docking and positioning controls.

Plasma Fusion Cylinders – The plasma fusion process creates a cylinder wall surface that is 60% harder than steel, removing the need for conventional steel cylinder sleeves. This significantly reduces weight, improves fuel efficiency and increases the engine capacity, resulting in an improved power-to-weight performance.

XTO OS Series SDS Propeller – Exclusively designed for the XTO Offshore outboard, the specially designed large surface area blades generate extreme thrust for excellent acceleration, cruising, top-end speed and reduced ventilation. Includes Yamaha’s Shift Dampening System (SDS) for quieter, smoother and ‘clunk free’ gear shifting.

Direct Fuel Injection – First four-stroke outboard to use direct fuel injection in the outboard industry. A three stage fuel pump system sprays fuel at high pressure directly into the combustion chamber, resulting in better fuel burn, more power and improved fuel efficiency.

Thrust Enhancing Exhaust Routing – Blade slippage is decreased significantly when in reverse due to the exhaust gases being ducted through a ‘relief’ bypass located above the anti-cavitation plate. This improves braking capacity and reduces vibrations through the boat.
