450 hp on less-expensive 89-octane gasoline

Impressive 5-year Limited Warranty, for pleasure use

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

XTO (SDS) PROPELLERS: With diameters from 16 to 17 1/8 inches, 15 to 27-inch pitches and increased blade surface, XTO propellers complement the torque potential of our V8 XTO Offshore. They also contribute to greater overall thrust

IN-WATER GEAR LUBE CHANGE SYSTEM: For the ultimate convenience, a technician can drain and replace your outboard 27s 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 AE 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

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 AE EX: Helm Master EX now features more than 10 automated modes, including new DriftPoint AE 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
