Yamaha’s award-winning 5.6L V8 XTO Offshore outboards, and their innovative engineering, set the bar for power and performance offshore. With extreme control, precision and reliability the XTO Offshore lets you go further, faster and with more confidence than ever before. Packed with industry-first technology like a direct-injection four-stroke powerhead, an award-winning charging system and integrated all-electric steering, the word outboard is an understatement. 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 F425.
The XTO Offshore® is the result of years of collaboration with top boat designers, and has been built from the ground up to provide the ultimate in power and efficiency offshore. With impressive stats such as 12.2:1 compression ratio for impressive fuel economy and power, industry firsts such as an electric steering system and engineering touches such as iridium spark plugs and quad thermostats, it’s purpose-built for extreme power, durability, control and reliability.
KEY FEATURES
Thrust-Enhancing Reverse Exhaust: For more control at lower speeds and increased precision of our Helm Master® EX boat control system, exhaust is diverted away from the propeller at RPMs below 2,500.
Pump Stop Power Tilt Limit: The tilt pump shuts off when it reaches maximum tilt setting, rather than continuing to run, saving power and reducing noise at full trim in/out.
Wide-Span Mounting System: For minimized vibration and a more compact design, incredibly strong upper motor mounts placed wide on the exterior of the upper mid-section work in conjunction with our Long Span Mounting System.
Phase Angle Control Charging: The XTO’s NEW Phase Angle Control Charging System meets the extreme electrical needs of today’s larger boats. This Innovation Award-winning new system produces up to 96 amps of net charging power at idle—from a single outboard—and up to 480 net amps in a quint configuration. This is up to 65 percent more maximum net charge at idle than the previous XTO model.
