Mercury Marine 6.2 Litre V8 Sterndrive Motor

MerCruiser’s all-new 6.2-litre V-8 Sterndrives review

Issue 112 Mercury Marine 6

MerCruiser’s new 6.2-litre V-8 300hp and 350hp sterndrives are purpose-built specifically for marine use.

Engineered with state-of-the-art technology, the engines offer new features like a long runner scrolled intake manifold that optimises air flow for higher torque, which translates into greater acceleration and improved boat performance.

The engine’s high displacement ensures it produces an outstanding power-to-weight ratio, pushing your boat onto the plane more quickly, staying on plane at lower speeds and handling rough seas better.

The 6.2L V-8 also offers Adaptive Speed Control (ASC).

This automatically maintains a set rpm point regardless of load or changing conditions such as tight turns, lower speeds on plane and tow-sport activities – or towing a record catch back to port.

This gives increased throttle response and a sportier feel at the helm. You won’t need to make continual throttle adjustments.

For the ultimate in manoeuvrability and easier docking, the new engines with Digital Throttle and Shift (DTS) can be partnered with Axius Joystick Piloting.

An air-intake resonator suppresses harsh sound frequencies making it dramatically quieter, while an all-new aft-facing throttle body directs noise away from the cockpit so conversations are easier.

Durable cast-iron componentry has been used wherever the engine encounters raw water, enhancing the anti-corrosion protection system.

Elsewhere in the engine, composites and marine alloys provide lightweight efficiency.

The 6.2L is available with optional freshwater cooling and the SeaCore drive anti-corrosion treatment, providing extra protection.

 Freshwater cooling uses a heat exchanger and coolant fluid to maintain engine temperature.

The coolant travels through the entire engine and the exhaust manifolds, and prevents internal corrosion of the cooling passages.

Mercury backs these engines with two years of Limited Warranty. The 6.2L also enjoys a three year anti-corrosion warranty.
