Digital: 425 hp
Yamaha’s award winning 5.6L V8 425-hp XTO Offshore is designed from the ground up to be smarter, more powerful and more efficient than anything you’ve seen offshore. With its extreme control, precision and reliability, the XTO Offshore lets you go further, faster and with more confidence than ever before. With industry-first technology like a direct-injection four-stroke powerhead and an all-electric steering system, it’s so much more than an outboard. It’s a fully integrated power system. And it’s elevating the entire offshore boating experience. Aim for the horizon – and beyond – with the Yamaha XTO Offshore.
The XTO Offshore DEC is a product of our CommandBlue™ philosophy, approaching engineering and design from the perspective of the boater, resulting in user-friendly products that increase customer satisfaction and confidence on the water.
The XTO Offshore’s award-winning Phase Angle Control Charging System creates up to 96 amps of net charging power per outboard at idle. That’s up to 480 with quints. In addition to powering a range of critical onboard tech, it prioritizes charging to the starting batteries, for incredible reliability offshore.
Maximizes power and efficiency by spraying fuel at high pressure directly into the combustion chamber. 
A three-stage low-medium-high pressure fuel pump system works, in part, due to two independent, rpm-activated fuel pumps in the Vapor Separator Tank. This unique five-pump system creates an unprecedented fuel injection pressure of up to 2900 PSI to further maximize atomization and efficiency.
Intake tracks enter the cylinder head from the outside of the powerhead. This gives exhaust gases room for a direct route to the lower unit and out through the propeller hub, streamlining the powerhead and improving flow.
