Performance without compromise. From the cowl to the prop, Mercury Racing engineers sought to redefine the capability of our highest-performance outboard motor. The 450R is armed with battle-tested design features and innovative technology.
Gearcase
The surface piercing Sport Master gearcase delivers race-proven performance for boats capable of speeds exceeding 85 mph, with low water pick-ups and a crescent leading edge to maximize efficiency and speed. The available cambered skeg counters prop torque for improved control in single-engine installations. The 450R is also available with the 5.44 HD gearcase designed for submerged applications.
Advanced
The 450R was engineered for life at wide-open throttle. The rugged Advanced MidSection (AMS) features heavy-duty guide plates and stiffened engine mounts to stabilize the outboard for enhanced high-speed handling. AMS isolates the powerhead from the transom to ensure run quality is smooth and quiet at all speeds.
Tie Bar
An integral rear tie bar bracket provides a strong, ultra-light mounting point and uncluttered installation for catamaran and other multi-engine rigging.
Personalized
The 450R is easily configurable for a variety of applications. Choose your options including gearcase, tie bar, and accent colors, plus available Joystick Piloting for Outboards (JPO).
