Yamaha Marine kicks off 2023 with new product offerings including an updated XTO Offshore outboard which delivers greater convenience, enhanced technology, and 450 horsepower. Featuring the same 5.6-liter big block displacement and long list of features as the original XTO 425, the updated XTO 450 improves upon the powerful platform that changed the offshore boating game.
“The XTO 450 allows boaters to enjoy the convenience and ease of operation associated with the XTO line in addition to more torque and power,” said Ben Speciale, President, Yamaha U.S. Marine Business Unit.
To help meet the extreme electrical demands of today’s larger boats, the Yamaha XTO Offshore 450 now boasts more charging power. Its Phase Angle Control componentry creates a super-strong magnetic field that produces 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 onboard generator. The system also prioritizes charging to the starting batteries, keeping them charged and ready for action at all times.
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.
In addition, 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. yamahaoutboards.com/en-us/utility/news
