Greetings from Nashville where we just revealed the all-new 450R outboard. Developed for discerning performance boating enthusiasts demanding unmatched power and performance, the 450R delivers outstanding power density at 450 propshaft horsepower from an outboard weighing as little as 689 pounds (313 Kg).
Literally hundreds of pounds lighter than the nearest competitor, the new 450R delivers industry leading power-to-weight in a compact, efficient and sporty package. Best of all, the Mercury Racing 450R delivers all of its performance on readily available 89-octane (95 RON) pump fuel.
Supercharged Performance The 4.6-liter V8 FourStroke powerhead is boosted by an exclusive Mercury Racing supercharger to produce 450 peak propshaft horsepower and 40 percent higher torque than the powerful 400R. The carefully considered design and placement of the new supercharger and charge-air coolers allow the 450R to use the same slim-line cowl as the 300R model while incorporating higher flow intake vents.
Like all Mercury Racing outboards, the 450R accommodates 26-inch center-to-center mounting on multi-engine transoms, perfect for optimizing use of transom space on new boats or re-power installations.
Inspired Engineering The exclusive Mercury Racing Advanced MidSection (AMS) features heavy-duty stainless steel guide plates and stiffened engine mounts that stabilize the outboard and enhance high-speed handling.
An optional rear tie-bar bracket integral to the AMS provides a strong, ultra-light mounting point and uncluttered installation for catamaran and other high-speed applications.
Gearcase Options The surface-piercing Sport Master gearcase, designed for boats capable of speeds in excess of 85 mph, features low water pick-ups and a crescent leading-edge for maximized efficiency, and for the 450R application, a stout new one-piece 1.25-inch diameter stainless steel propshaft.
From single-engine performance runabouts to multi-engine catamaran sport boats the Sport Master – in the correct application – will enhance boat handling, speed and efficiency. The available cambered skeg counteracts prop torque for improved performance and handling in single-engine applications.
The 450R is also available with the 5.44 HD gearcase for lower-speed and traditional submerged applications. All 450R gearcases have a 1.60:1 gear ratio for enhanced acceleration and speed.
Mercury Racing Propellers Mercury Racing propellers are designed to maximize boat performance and handling in any application. Our artisans handcraft each propeller to precision-tuned works of art, customized for specific boat types and performance goals. Each individual propeller is then zero balanced and measured to ensure consistent performance every single time.
On the new 450R models, the popular MAX5 and Outboard CNC Cleaver props are required for use with the surface piercing Sport Master gearcase. For 5.44 HP gearcase applications, Mercury Racing’s Bravo I FS, Bravo I LT, Enertia ECO XP, and Rev 4 XP are excellent options.
Intelligent Technology Mercury Transient Spark Technology applies pre-programmed timing advance to optimize torque output for stronger hole-shot performance. Adaptive Speed Control with a custom Mercury Racing calibration automatically holds engine rpm regardless of load or condition changes – such as rough water, tight turns, tow sports and lower speeds on plane – to maintain boat momentum with less-frequent throttle control adjustment.
The 450R is compatible with Mercury Racing Zero Effort Digital controls or any Mercury Marine digital control system, which can throttle up to six outboards with a single lever in some applications. Digital throttle and shift technology enhances the high-performance boating experience by providing smooth shifting and instant response while eliminating cable rigging and maintenance.
Optional Joystick Piloting for Outboards (JPO) is available for boats rigged with two to six outboards and provides intuitive, fingertip 360-degree boat control for docking and maneuvering in tight quarters, plus the convenience of Skyhook® sea-holding features and integrated auto piloting.
An available Mercury VesselView offers more systems information and engine data than with any other display system in the boating industry. VesselView can simultaneously monitor the RPM, speed, fuel flow and efficiency, temperature, trim and more on up to six outboards on an intuitive seven or nine-inch touchscreen display.
VesselView also enables Advanced Sound Control, a dual muffler system that can be toggled between an ultra-quiet mode and a deep sport tone with a stirring growl on start-up.
Unmatched Reliability Designed to thrive in the abusive environment of high-performance boating, the 450R was tested, tested and tested again – in the lab and on the water – in a never-ending quest to exceed the highest expectations of the most-demanding customers. Run Wide Open with confidence.
The Mercury Racing 450R outboard is backed by a three-year limited factory warranty and a three-year limited corrosion warranty. Extend that coverage for up to five additional years with a Mercury Product Protection factory-backed extended service plan.
The Mercury Racing 450R is available in Cold Fusion white and the legendary Mercury Phantom Black. Cold Fusion White models are finished with Devil Red Eye cowl accent panels with a white Advanced MidSection (AMS) and gearcase. Black models are finished with Graphite Grey cowl accent panels and matching Graphite Grey AMS and gearcase. Devil Red Eye, Graphite Grey and Carbon Fiber accent panel kits are available to custom-match a 450R outboard to a boat color scheme.
Production of the all-new 450R is underway and customer shipments have begun.
