XTO Offshore V8 5.6L 425 HP
INDUSTRY’S FIRST DIRECT-FUEL-INJECTION FOUR STROKE
Maximizes power and efficiency by spraying fuel at high pressure directly into the combustion chamber. It’s the first four-stroke powerhead in the outboard industry to feature direct injection.
Make an appointment with Tom Ross to come in and see this motor in person.
Electric Steering
The XTO responds quicker to steering inputs because it contains the industry’s first electric steering motor, which directly sends signals form the helm to the integral electric steering control unit.
Helm Master® EX
Make the most of every minute on the water with the incredible control of Helm Master EX. Helm Master EX is built on the success of our groundbreaking, original Helm Master boat control system. It expands upon the functionality, flexibility and compatibility of our original Helm Master system, for an exciting next generation of control.
CL7 Touchscreen Display
Yamaha’s CL7 7-inch touchscreen display is our most streamlined instrumentation and is compatible with the new V8 XTO Offshore.
