Tons of Thrust and Technology.

The muscular new shape and dynamic look of the XF375 XTO immediately communicate its incredible industry-first concepts and technologies waiting to be unleashed.

The first direct injection 4-stroke. The first with integral electronic steering, linking seamlessly to Yamaha’s Helm Master® system. The first to achieve a new level of reverse thrust, torque, and speed. It’s a genuine performance revolution for larger boats and an incredible story.

Karakteristike

This highly efficient system, actually built into the motor unit itself, is not only lighter and less complex than a separate hydraulic system, but is cleaner to fit and operate. What’s more, the response time for the helmsman is faster and more precise – and the result even smoother.

That’s why the XF375 XTO has thoughtful features like these: The facility for an in-water gear oil change – with the boat still at the dock. A multi-part cowling that has quick-access locks and allows secure, easy access for maintenance and adjustments. A High Output system to provide stable 72A charging – and 58A charging even at low rpm.

At the heart of this flagship powerhouse is Yamaha’s very latest technology, taken to new levels. With features like 5-pump Direct Fuel Injection, VCT (Variable Camshaft Timing), DOHC (Double Overhead Camshafts), dual chamber oil pump, 2-stage water pump, quadruple thermostats, our unique in-bank exhaust system … the stage is set.

With our constant quest for ever-greater efficiency and economy, industry firsts often happen at Yamaha and the fuel system on the XTO outboards is a good example – it’s the first-ever Direct Injection 4-stroke engine. In fact, the XTO outboards are packed with such advances, from the in-water oil change facility to the thrust-enhancing exhaust system.

There can be no compromise on build quality and reliability at this level, so every bit of the XTO engines are built super-tough. From the massive crankshaft to the torque-absorbing heavy duty gears – and from the extra-large diameter prop shaft to the completely new gearcase design, with its low friction co-efficient and better cooling.

This engineering concept expels the exhaust via a combination of three different routes, depending on the RPM level. Put simply, the result is around 300% more reverse thrust (than it would have without these measures) and better balance between forward and reverse thrust when manoeuvering with Helm Master® – plus greater efficiency at full power.

XTO stands for Xtreme Thrust Output because this awesome V8 unit delivers a totally new generation of power, performance and precision control never before available. Together, our XF375 and XF425 XTO engines and unique Helm Master® system provide a seamlessly integrated total power and control solution for larger offshore boats. Explore the Extreme.
