Yamaha V8 XTO Offshore™ Outboard Offers the Extreme

Industry Firsts Include Direct Injection and Integrated Electric
Steering System

KENNESAW, Ga.–(BUSINESS WIRE)–The new V8 XTO Offshore outboard is designed to take Yamaha’s premium
quality brand position to a higher level with extreme power and thrust,
toughness and reliability, system integration, control, convenience and
customer care. Yamaha has achieved many of these extremes by rethinking
the outboard and its related systems, and through the application of
technologies new to the industry.


“This is an integrated outboard system, designed to push the heaviest
offshore boats and yachts,” said Ben Speciale, Yamaha Marine Group
President. “The new Yamaha V8 XTO Offshore has 5.6-liters tremendous
thrust and 425 horsepower. The V8 XTO Offshore provides extreme
performance for the biggest boats. Combine it with the latest generation
of Helm Master® and Yamaha’s CL7 Display, and you
have benefits offered nowhere else.”

Extreme Power and Thrust

Pushing the heaviest offshore boats and yachts requires driving extreme,
large propellers, a massive, rugged gearcase and an extreme powerhead.
As the first four-stroke powerhead in the outboard industry to use
Direct Injection, the V8 XTO Offshore is already a legend, spraying fuel
at high pressure directly into the combustion chamber, rather than the
intake track, just before the intake valve. This greatly improves
atomization and increases the effectiveness of the fuel burn for maximum
power and efficiency.

The Direct Injection system features five fuel pumps and injection
pressure up to 2900 PSI. The three-stage fuel pressure system is in part
comprised of two independent fuel pumps within the Vapor Separator Tank
(VST) that activate at specific, individual RPM. This ensures proper
fuel flow and delivery, even at very high engine RPM.

Yamaha’s V8 XTO Offshore also boasts the highest compression ratio in an
outboard – 12.2:1. This means more “bang” from every spark, as well as
better efficiency and power.

The new XTO OS™ propellers for boats and yachts are made to complement
the torque potential of the Yamaha V8 XTO Offshore. These new propellers
produce more thrust in both forward and reverse, using diameters from 16
to 17⅛ inches. The increased blade surface area is designed for moving
big boats and yachts.

The In-Bank™ Exhaust feature means intake tracks enter the cylinder head
from outside of the powerhead, allowing space for exhaust gases to have
a direct route to the lower unit and out the propeller hub, improving
flow.

Extreme Toughness and Reliability

In addition to an oversized gearcase, hardened gears, a robust, offshore
bracket and motor mounts, the V8 XTO Offshore outboard also features
proven plasma fusion technology for durability and lighter weight. The
outboard also has a two-stage water pump and dual chamber oil pump, each
designed to respond to the heavy loads associated with high RPM
operation.

Dual overhead, endurance-driven camshafts on each cylinder bank are
connected via a self-tensioning chain immersed in an oil bath for
accurate valve timing and long life, delivering quiet and precise
connection for proper and consistent valve timing. One sprocket belt
engagement means a narrower, more compact overall profile.

Carbon-coated shimless bucket-type valve lifters also increase
durability, while a dual-chamber oil pump ensures proper oil flow and
delivery at every engine speed.

Plasma fusion replaces conventional steel cylinder liners. The
micro-textured surface is 60 percent harder than steel and significantly
lighter, contributing to increased displacement without increasing the
size of the powerhead. The resulting surface also increases fuel economy
by decreasing internal friction.

Spark plugs made from iridium, one of the rarest elements on earth and
the second hardest, yield improved throttle response, economy, increased
service life and improved power. The new V8 XTO Offshore outboard also
features quad thermostats, two thermostats per cylinder bank, for
improved flow and better regulation of engine and oil temperature.

A uniquely designed two-stage water pump features a massive rubber water
impeller for high pressure and flow. A steel impeller helps provide
sufficient water volume even under the most extreme offshore conditions.
This configuration provides proper cooling water flow at all RPM and
improved temperature control.

Extreme System Integration

The V8 XTO Offshore has integrated electric steering, the first of its
kind in any outboard. The integrated steering system has no hydraulic
lines or linkages, and responds more quickly than conventional systems
to steering inputs. In addition, integrated electric steering means
reduced power consumption, clean rigging, and a very orderly bilge area.

The new V8 XTO Offshore outboard also features an Integral Electronic
Steering Control Unit that receives signals from the steering cylinder
position sensor to carry out joystick and steering operation. Functions
integrated into the electric steering system on Yamaha V8 XTO Offshore
outboards include: joystick calibration, lever sensor, toe-in/out
adjust, joystick thrust, lock to lock, and steering friction set.

Helm Master® and the CL7™ Display have also been updated
along with the launch of the new XTO Offshore outboard.

Extreme Convenience, Control and Customer Care

Thanks to an ingenious new exhaust-gas relief system, V8 XTO Offshore
propellers bite clean water in reverse, which helps yield reverse thrust
up to 300 percent of that developed by Yamaha’s F350. That means easy
maneuvering and more control in docking, particularly when the V8 XTO
Offshore is matched with Yamaha’s Fully Integrated Boat Control System,
Helm Master®.

Boats powered by the V8 XTO Offshore need go no further than the dock
for a lower unit service, thanks to a unique gearcase lubricant exchange
system that allows fluid change in the water. In addition, the V8 XTO
Offshore also has great charging capabilities, providing up to 90 amps
of total (gross) power and reaches peak net output around 1,500 RPM
where it is needed most.

Backed by the best-trained dealer network in the industry and a
five-year limited warranty for pleasure use, the V8 XTO Offshore also
has the functionality to facilitate a comprehensive maintenance tracking
tool.

All of these benefits—coupled with Yamaha’s reputation for great resale
value—assure Yamaha V8 XTO Offshore owners will have an experience
second to none.
