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 Midsection: 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 Bracket: An integral rear tie bar bracket provides a strong, ultra-light mounting point and uncluttered installation for catamaran and other multi-engine rigging.
• Personalized Power: 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).

• Digital Controls: Mercury Racing Zero Effort digital controls provide smooth shifting and instant response while eliminating cable maintenance.
• Joystick Piloting for Outboards: Available for boats rigged with two to six outboards, JPO provides intuitive 360-degree boat control for maneuvering in tight quarters plus Skyhook® sea-holding features and integrated auto piloting.
• Adaptive Speed Control: Adaptive Speed Control automatically holds engine rpm as load or conditions change to maintain boat speed with less throttle input.
• Alternator and Idle Charging: Exclusive Idle Charge technology automatically senses low battery voltage and increases idle RPM to boost alternator output.
• Top Cowl Service Door: Pop it open for routine engine oil checks without removing the cowl. An integrated latch and carry handle eases cowl removal for service.

• Unparalleled Efficiency: No wasted weight. No wasted fuel. No wasted hours. The 450R offers durability and efficiency that rivals its impressive performance. Every ounce of each component was scrutinized to achieve maximum power with minimal weight. Reliability is built in, so you can run Wide Open with confidence.
