Power and Performance

DIRECT-INJECTION FOUR STROKE

Maximizes power and efficiency by spraying fuel at high pressure directly into the combustion chamber.

EXCLUSIVE FUEL SYSTEM

A three-stage low-medium-high pressure fuel pump system works, in part, due to two independent, rpm-activated fuel pumps in the Vapor Separator Tank. This unique five-pump system creates an unprecedented fuel injection pressure of up to 2900 PSI to further maximize atomization and efficiency.

IN-BANK EXHAUST

Intake tracks enter the cylinder head from the outside of the powerhead. This gives exhaust gases room for a direct route to the lower unit and out through the propeller hub, streamlining the powerhead and improving flow.

Convenience and 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.

System Integration

DIGITAL ELECTRIC STEERING

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

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.
