MERCURY RACING 450R

In Stock
Born out of a passion for perfection, Mercury Racing Verado 450R engines have taken the risk of elevating the performance of outboards. Serious improvements have been made to the proven powerful turbocharged 4.6lt twin overhead cam engine to deliver incredible advances in engine power and performance. Limiting full power revs to 7000 rpm for ultra-quick acceleration, expert tuning from Mercury Racing and an impressive power-to-weight ratio are just the beginning of the evolution 450R engines provide.
 
Color options

An optional Graphite Gray decorative fillet/engine panel is available as a kit. There is also a kit of primed fillets, ready to be painted, for those who want colors other than the basic ones, to give a personal character to the aesthetic harmony of the engines with their boat.

Intuitive, innovative features
Unparalleled torque
Mercury's exclusive Transient Spark system, which increases up to 7% torque during planing by optimizing spark plug timing and fuel injection regulation, achieves faster planing of the boat. All that displacement and power is channeled through a compact and lightweight package with 26-inch engine spacing, ideal as an upgrade or multi-engine solution

New and bold aesthetics
The aggressively designed and styled engine cover defines a new era of propulsion through high performance outboards from Mercury Racing. Fresh in design and with excellent aesthetic graphics and decorative fillets in a bright red color (Devil Red) "shout" from afar that they are bursting with performance.

The cover is kept in place
For easy checking of the engine oil level or topping up, simply open the handy and watertight hatch on the top of the engine cover. Even smarter is the optional electronic oil level measurement system, which uses a sensor to measure the oil level when the engine is started, warning the operator of a low oil level.
