Overview

Built for the water you run

LXF450XSA is the 25″ counter-rotating XTO Offshore option—450hp for boats that don’t need an ultra-long shaft but still want Yamaha’s top-tier offshore power system. A clean fit for many dual-console and mid-size offshore hulls running matched twins.

  • 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.
