XTO Offshore

Digital: 450 hp, 425 hp

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—and now up to 450 horses—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 F450 and F425.

RELIABLE BY DESIGN

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.

CONVENIENCE & CONTROL

IN-WATER GEAR LUBE CHANGE SYSTEM

For the ultimate convenience, a technician can drain and replace your outboard’s lower-unit lubricant without having to remove your boat from the water.

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.

DUAL FLUSH SYSTEM

A unique design offers two methods for flushing the XTO, either through a built-in flushing system hose routed through the rigging tube/grommet or through conventional front-mounted direct-hose hook-up.

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.

IMPROVED RIGGING TUBE

A redesigned rigging tube provides an extra 3.25 inches of clearance at the motor well when tilted up, and is compatible with most flat-transom installations.
