Yamaha V8 XTO Offshore: Extreme power, torque and thrust

Yamaha officially launched the all-new V8 XTO Offshore. With 5.6-litres of brutal torque and thrust – and 425 exhilarating horsepower – it really is more than simply an outboard. The new V8 XTO Offshore is designed to take Yamaha’s premium quality brand position to an even higher level, with massive power and thrust, unmatched toughness and reliability, unprecedented system integration and precision control, along with ultimate convenience and customer care.

Yamaha has achieved this by ‘rethinking’ the concept of the outboard and its related systems, by the application of technologies new to the industry – and of course, by calling on the many, many years of dedicated experience in outboard technology and production forwhich Yamaha isrenowned theworld over.

Delivering the sheer brute force needed to ‘push’ the heaviest and largest offshore boats and luxury RIBs requires massively rugged gear cases and the toughest powerheads ever made, working hard together to drive very large propellers. Here, the XTO Offshore is already unique, being the first 4- stroke in the industry to use Direct Injection. The high-pressure injection of fuel directly into the combustion chamber greatly improves atomization and increasesthe effectiveness ofthe fuel burn for maximum power and efficiency.

The advanced Direct Injection system features no fewer than five fuel pumps – and generates injection pressure up to 200 Bar! The three-stage fuel pressure system also features two independent fuel pumpsthat activate atspecific, individual RPMlevels within a Vapor Separator Tank (VST). This ensures unprecedented high-precision fuel flowand delivery, even at max RPM. Yamaha’s V8 XTOOffshore also boasts an incredible compression ratio of 12.2:1. The In-Bank™ Exhaust feature gives the gas a direct route to the lower unit and out via the centre of the propeller hub, improving the flow.

XTO has a unique two-stage water pump and a dual chamber oil pump, each designed for consistent operation at high RPM. Together, they provide high volume cooling water flow and accurate temperature control at all RPMlevels, even underthe most extreme offshore conditions.

In addition to an oversized gearcase, hardened gears, a robust, offshore bracket and super – strength motor mounts, the V8 XTO also features plasma fusion technology for the cylinder liners, not only for durability, but also for a more compact engine..

Another ‘Industry First’ for the V8 XTO is its fully integrated electric steering system, the first of its kind on any outboard. It has no hydraulic lines or linkages, so responds more quickly and smoothly than conventional systems. In addition, it allows for cleaner rigging and an orderly bilge area. Of course, the ultimate control solution is to team the V8 XTO with Yamaha’s unique and hugely successful Helmmaster® fully integrated boat control system, with its revolutionary joystickcontrolled docking facilities and outstanding CL7™ colour display.

The special new XTO OS™ propellers are made to complement the huge torque potential of the Yamaha V8 XTO Offshore. These new props produce more thrust in both forward and reverse, using diameters from 16 to 17⅛ inches. The latest blade design, with its huge surface area moves the very biggest boats with less effort and more control.
