The Next Generation

Featuring a host of engineering innovations, the 4.5L series establishes new standards for power-to-weight ration, driver experience, acceleration, durability and ease of maintenance.

 

Sporty Handling
The 4.5L comes standard with Adaptive Speed Control, which automatically maintains engine rpm regardless of load or water conditions. The result is increased throttle response and a sporty feel.
Sporty Handling
Easy to Maintain
When service is required, maintenance is a snap with the front-mounted drive lube monitor, color-coded maintenance points - including easy-to-reach oil filter and fill - and "how-to" videos that can be accessed via the QR code on the label.
Easy to Maintain
Smooth & Quiet
The 4.5L's newly designed rear-facing throttle body, anti-whistle throttle plate, engine cover and mounts, lightweight flywheel, fuel-supply module, and structural oil pan all work together to deliver a superior idle, smoothness and low vibration. Resulting in an exceptional driving experience.
Smooth Quiet
Built for Marine
Designing a V-6 block solely for marine use allows Mercury to build the 4.5L with the ultimate protection system, using cast-iron componentry where the engine intersects with seawater, and using corrosion-resistant aluminum and composites everywhere else.
Built for Marine
Corrosion Protection
The MercFusion Paint System creates an outer seal against the elements, while MerCathode provides automatic protection against galvanic corrosion. For maximum defense against saltwater effects, the SeaCore industrial hardcoat anodizing system and closed-cooling circuit is available with the Bravo drive.
Corrosion Protection
Powerful Performer
Thanks to its new, long-runner scroll intake manifold which draws in more air and converts it into additional torque, the 4.5L delivers a ground-breaking power-to-weight ratio and gives you V-8 power in a V-6 package.
