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. 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. 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. 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. 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. The XTO’s Phase Angle Control Charging System meets the extreme electrical needs of today’s larger boats. This Innovation Award-winning 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. That’s up to 65 percent more maximum net charge at idle than previous XTO Offshore models. 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.

The XTO responds quicker to steering inputs because it contains a digital electric steering motor, which directly receives signals from the electric helm to the integrated steering control unit. Helm Master EX now features more than 10 automated modes, including new DriftPoint® Track, which helps to automate the drifting of an uneven shoreline; new Autopilot with Heading and Course Hold; the expanded ability to control up to five outboards, and more.

Endurance-Driven Camshafts - The XTO features dual overhead camshafts that are each connected via a self-tensioning chain immersed in an oil bath and utilize one-sprocket belt engagement. This ensures quiet, precise valve-timing, compact design, low maintenance and long life. The XTO's dual chamber oil pump ensures the proper flow and delivery at every engine speed. A special carbon coating on shimless, bucket-style valve lifters increases durability and requires less maintenance. Plasma-Fused Sleeveless Cylinders - A micro-textured, plasma-fused design increases fuel economy and is lighter, more compact and 60 percent harder than steel. This allows us to enlarge cylinder bores and increase displacement without increasing the size of the powerhead, all while dramatically reducing friction. Two-Stage Water Pump - This unique design ensures proper cooling water flow at all RPMs and improved temperature control. It features a massive rubber water impeller for high pressure and flow, and a steel impeller that helps provide sufficient water volume, even under the most extreme offshore conditions.
