From sporty handling and smooth performance to efficient V6 power, every aspect of the MerCruiser® 4.5l sterndrive was engineered to elevate your boating experience. It is fun days and memorable moments from here on.
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.
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.
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.
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.
Hear your friends and family talk. Hear yourself think. Enjoy your time on the water. A MerCruiser engine is still as powerful as ever. Thanks to sound-dampening advancements, it is just not so loud about it.
High-displacement engines and multi-port fuel-injection systems maximise the performance from every drop of fuel. You will enjoy quick acceleration, instantly responsive power and total fun.
A redesigned engine access has simplified what was once a hassle, bringing all service points to a single easily reachable location, colour-coded for owner-friendly maintenance.
Through gruelling endurance test cycles – in the lab and on the water – Mercury has refined every MerCruiser engine into an unflinching workhorse, built with better alloys and superior paints that can stand up to the harshest conditions.
