Up for auction is a pair of used Mercury Racing 450R XL & CXL outboard engines. No rigging, controls, steering, gauges, or propellers are included.
We are a Mercury Outboard dealer and just took this pair of engines in on trade. The customer decided to upgrade to a new pair of Mercury 500R Engines. These engines are very clean and we just fully serviced them. The engines are ready for installation/ use.
We just performed a complete service on these engines per Mercury Spec. 300 Hour Engine Service. The service consisted of an engine oil and filter change. Fuel filters have been replaced. New belts, spark plugs, thermostat, water pump assembly, and a gear lube change. These engines run great and compression (160-165 PSI Per Cylinder). These are a very clean pair of used 450R Outboard engines. The engines are ready to be installed for use.
Engine Details:
GO FARTHER, FASTER WITH THE 450R V-8 FOURSTROKE
Handcrafted by Mercury Racing for the high-performance disciple craving unrelenting power, the Mercury Racing 450R makes the paramount performance statement. Boosted by an exclusive Mercury Racing supercharger, the 4.6-liter V-8 FourStroke powerhead delivers 450 peak horsepower while staying 136 Kilos lighter than the nearest competitor. Run wide open, without compromise.
ADVANCED MIDSECTION INTEGRATED TIE BAR
POWER STEERING:
Each ounce
was scrutinized to achieve maximal power with minimal weight. The Mercury
Racing Advanced MidSection (AMS) features heavy-duty guide plates and stiffened
engine mounts to stabilize the outboard for enhanced high-speed handling.
The AMS also isolates the powerhead from the transom to ensure run quality is
smooth and quiet at all speeds. 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. The 450R is
offered with a choice of the 5.44-inch HD gearcase for traditional, submerged
applications or, for boats capable of speeds over 136 km/h, the
surface-piercing Sport Master gearcase with a new one-piece stainless steel
propshaft.
SUPERCHARGER CHARGE-AIR COOLERS BOOST
BYPASS:
Mercury
Racing applies its supercharging expertise to extract incredible power from the
4.6-liter V-8. A 2.4-liter twin-screw supercharger delivers pressurized ambient
air to the intake tract for instant throttle response. The supercharger is
water-cooled to reduce the temperature of the intake charge and increase power.
A boost bypass valve automatically adjusts maximum boost pressure to maintain
peak performance in response to changing ambient conditions. A custom-designed
attenuator is tuned to cancel the harshest high-frequency supercharger noise.
The Mercury Racing 450R is fitted with a special high-capacity oil cooler and
an exclusive poppet valve in the midsection to provide a higher volume of
cooling-water flow on-demand. The valve train features a high-performance
intake camshaft and race-spec Inconel exhaust valves. Wide-open throttle (WOT)
operating range is extended to 5800-6400 rpm to expand propping options and
maximize performance.
RUGGED MIDSECTION CORROSION PROTECTION
3-YEAR WARRANTY:
Mercury
Racing V-8 outboards are engineered to be reliable and durable. These
high-performance outboards are tested, tested and tested again – in the lab and
on the water – in a never-ending quest to exceed the highest expectations. Run
wide open with confidence.
LOWER UNIT DETAILS:
The 5.44″
Offshore HD gearcase was designed and engineered by Mercury Racing for the most
