The new MerCruiser 6.2 litre V8 sterndrive engine has power to spare

Published on: 09/09/2015

Mercury MerCruiser’s new 6.2 litre, V8, 300hp and 350hp sterndrive engines, deliver increased power and torque while providing a remarkably quiet and smooth ride.

Mercury has designed and built the 6.2L engine specifically for marine use rather than adapting and marinising an automotive engine. The 6.2L is not burdened with automotive restrictions and unnecessary technologies that result in additional cost and complexity without adding value. The result is a perfect balance of power, easy maintenance, superior corrosion-resistance and a quiet, pleasurable ride.

Power, acceleration and performance

The MerCruiser 6.2L engine offers class-leading acceleration while delivering smooth operation. A long runner scrolled intake manifold optimises air flow for higher torque, which translates into greater acceleration and improved boat performance. High displacement, which produces an outstanding power-to-weight ratio, provides a more enjoyable and safer boating experience by letting you plane your boat quickly, handle rough seas better and stay on plane at lower speeds.

The 6.2L V8 also offers Adaptive Speed Control (ASC), which automatically maintains a set rpm point regardless of load or condition changes, such as tight turns, tow-sport activities and lower speeds on plane. The result is increased throttle response, and a ‘sportier’ feel for the driver, who no longer has to make continual throttle-control adjustments.

An option for the 6.2L with DTS is Axius Joystick Piloting for Sterndrives, providing the ultimate in docking experience and manoeuvrability.

Smooth and quiet

An air-take resonator suppresses harsh sound frequencies throughout the engine operation for a dramatically quieter and more pleasurable on-board experience while an all-new, aft facing throttle body directs noise away from the cockpit for easier conversation.

Larger and optimised engine mounts isolate undesirable engine vibration and reduce resonant vibration sounds, making the ride even quieter and smoother.

Easy maintenance and service

The 6.2L features a maintenance centre near the top-front section of the engine; ensuring maintenance points are easily identifiable and accessible. Additionally, the valve train is maintenance-free for the life of the engine, and a QR code on the engine’s service label allows smartphone users to access ‘how to’ videos online. The 6.2L V8 also boasts a ‘season extending’ drain system that can keep you on the water during the transition times between seasons.

Ease of maintenance on the MerCruiser 6.2L includes the elimination of the traditional 20-hour service.

The 6.2L is available with optional freshwater cooling, and the SeaCore corrosion protection treatment provides extra corrosion protection only when needed, such as saltwater environments. Freshwater cooling uses a heat exchanger and coolant fluid to maintain engine temperature, rather than raw water from a lake or ocean. The coolant travels through the entire engine and the exhaust manifolds and prevents internal corrosion of the cooling passages. The SeaCore drive is a hard-anodising process that alters the surface layer of the aluminium drive casting to prevent saltwater penetration that leads to corrosion.

The MerCruiser 6.2L sterndrive engine joins the 4.5L that was launched at London Boat Show earlier this year.

“The MerCruiser 6.2L joins the extensive and proven portfolio of Mercury products that provide exceptional performance, fuel economy, durability, smoothness and quietness, combined with intuitive operation, service and maintenance,” comments Robert Plant, General Manager, Marine Inboard Division. “The engine is the perfect power option for mid-sized boats, 20ft-30ft, including runabouts, performance sports boats and cruisers.”
