Yamaha’s New XTO Offshore 450

Yamaha has introduced an updated XTO Offshore outboard that delivers enhanced technology and 450 horsepower. Featuring the same 5.6-liter of big block displacement as the original XTO 425, the updated XTO 450 improves upon the powerful platform.

More Charging Power

To help meet the extreme electrical demands of today’s larger boats, the Yamaha XTO Offshore 450 now boasts more charging power, featuring a three-phase, simultaneous charging system that delivers an incredible amount of net amps at low rpm, where it’s needed most.

Using Phase Angle Control (PAC) componentry to create a super-strong magnetic field, XTO Offshore 450 models produce up to 96 net amps per engine in neutral – plenty of power for today’s popular, high-demand devices such as gyro stabilizers, air conditioning and sound systems. The Phase Angle Control charging system on the new XTO Offshore 450 is so powerful, it can even eliminate the need for an on-board generator. The system also prioritizes charging to the starting batteries, keeping them charged and ready for action at all times.

Faster, Easier Engine Tilt

Every XTO Offshore 450 comes equipped with Yamaha’s exclusive TotalTilt® feature for faster, easier engine tilting. When enabled, it allows complete tilt up from any position with a simple double-push of the “UP” trim/tilt button, or full tilt down (until trim ram contact) by the same double push of the “DOWN” trim/tilt button. A warning horn sounds just before and during these operations. Movement and the horn can be stopped anywhere in between by pressing the tilt button again.

Updated Styling

New raised chrome graphics on the sides, a re-styled panel in back, a new flush-mounted manual flush connection up front and hidden external wiring near the bracket add to the premium look of this powerful outboard. There’s also an optional built-in propeller light (rather than transom mount) that illuminates when using Helm Master® EX SetPoint® features.

New Prop Options

New XTO EC® propellers are now available for applications where propeller ventilation may be an issue due to the power and torque of XTO Offshore outboards. Yamaha also adds a 27-inch pitch to its XTO OS® line of propellers for lighter weight XTO applications that have the available wide-open throttle rpm to potentially drive more top speed.

The new Yamaha XTO Offshore 450 will become available starting in the spring of 2023.
