MERCRUISER 4.5L STERNDRIVE
Featuring a host of engineering innovations, the 4.5L series establishes new standards for power-to-weight ratio, driver experience, acceleration, durability, and ease of maintenance.
PERFORMANCE
Smooth and quiet
From the mounts to the throttle system, we have fine-tuned the 4.5L engine to minimise noise and vibration – all for an exceptional driving experience.
Exceptional fuel economy
Electronic fuel injection optimises efficiency so you can get maximum fun from every fill-up. Plus, MerCruiser engines also deliver full performance on 87-octane fuel for additional savings at the pump.
Exciting speeds
Don’t waste a second on the water. With V6 muscle and performance, the 4.5L engine will get you where you want to go fast – and you will have a whole lot of fun on the way.
FEATURES
Advanced MPI
The multi-point electronic fuel injection system fine-tunes the air-to-fuel ratio for the ideal combination of power and efficiency.
Ample charging output
A powerful alternator delivers 70 amps of charging power at wide-open throttle – perfect for keeping onboard electronics running long into the fun.
Adaptive Speed Control
The Adaptive Speed Control feature lets you maintain engine rpm despite changes in load or conditions. Climbing large swells is easier. Cruising at low speeds is smoother. Carving out tight turns is effortless.
Engine guardian
Explore farther with confidence knowing that the engine guardian system is at work. It monitors the engine and, if necessary, can adjust engine functions to help get you home safely.

Take on the toughest marine conditions with the available SeaCore® system. It is an entire package of durable, corrosion-fighting technology that offers an extraordinary level of protection, including hard-coat anodisation on the drive, stainless-steel fasteners and components, and a closed cooling system.
