With the V12, Mercury continues to transform the high-horsepower outboard market.

THE WOW FACTOR

MERCURY’S V12 600 TAKES OUTBOARD INNOVATION TO THE NEXT LEVEL

Over the years we have seen some very innovative technology introduced into the marine propulsion market. Take for example the first sterndrive from Mercury Marine, the Duoprop and later IPS from Volvo Penta, four stroke and diesel outboards and now the talk is all about electric and hybrid. Well there is a new player that’s stepped up to challenge all that has gone before. Mercury Marine’s, 7.6 litre V12 600hp Verado outboard redefines outboard performance and takes innovation to the next level.

With this launch, Mercury continues to transform the high-horsepower outboard market, providing its most powerful and capable outboard, which includes several industry first features for a wide variety of applications.

“With boats continuing to grow bigger and performance expectations continuing to rise, boat owners have been asking for a better, more capable high horsepower solution to meet their needs. The V12 Verado outboard is Mercury’s answer,” said Chris Drees, Mercury Marine president.

“Using our advanced engineering and design capabilities, we completely redefined outboard performance. This is a remarkable engine that will change the future of boating.”

You would simply describe the V12 Verado as a beast of an engine. It is seriously large not only in horsepower but also statue. It weighs in at 572 kgs and requires a specially designed transom to mount to.

It is the world’s first V12 outboard, based on a naturally aspirated, large displacement, quad cam powerhead that generates impressive torque to get heavy boats out of the hole and on plane quickly, and to accelerate up to rated speed rapidly.

The V12 Verado outboard delivers everything you want and more in a high-horsepower outboard. This engine makes boats easy to manoeuvre near the dock and provides superior handling at all speeds.

Although Pacific PowerBoat magazine didn’t get the opportunity to run full fuel and performance tests on the 600hp V12, the well-respected boattest.com has performed a number of tests on 2/3/4 engine multi rigs.

Fuel consumption at maximum rpm (6400-6500) is around 190 lph per engine. Drop that back to a more sedate cruise of 4500 rpm and you can expect somewhere close to 95 lph per engine. At 3500 rpm the fuel drops to around 70 lph.

The gearcase pivots independently underwater while the engine’s powerhead remains in a space saving fixed position.

GAME-CHANGING GEARCASE

However, for all its features at the top end, it is what’s underwater that has seen the most significant change in outboard technology. This is where the wow factor comes into play. Then V12 Verado introduces not only the industry’s first two speed automatic transmission for an outboard optimises engine rpm according to workload, facilitating powerful acceleration and highly efficient performance at cruise, but also the first steerable gearcase.

The outboard’s powerhead — everything an observer can see above the water line — remains in a fixed position, perpendicular to the transom at all times. The steering occurs underwater, using a gearcase that pivots the engine’s contra rotating props to the right and left.

Advantages include the elimination of a boat mounted steering system and enhanced handling and manoeuvrability. Because the steering system does not have to move the entire engine, its performance is exceedingly agile.

Plus, while conventional outboards typically pivot 30 degrees in one direction or another for steering, the V12 Verado outboard’s gearcase can pivot up to 45 degrees in a particular direction under joystick operation. This provides much more authority to effectively manoeuvre a large boat. This feature, combined with the lower propeller speed in first gear, provides precise handling at docking speeds.

The gearcase pivots independently underwater while the engine’s powerhead remains in a space saving fixed position. This provides more room for multi engine configurations and a wider steering angle for agile handling. With help from contra rotating propellers, it also has better “bite” in the water for docking and other close quarters manoeuvring.

The two speed automatic transmission optimises engine rpm according to workload, facilitating powerful acceleration and highly efficient performance at cruise. First gear is 20% lower than second gear, leveraging the engine’s high torque to accelerate the boat and get it up on plane quickly. The engine continues to deliver robust power and acceleration through its power shift all the way to rated speed.

The V12 lower gearcase rotates 45-degrees to each side, 15-degrees more than standard outboards typically rotate on their mounts.

The gearcase system’s contra rotating propeller configuration improves performance with more total blade area. There is also a hydrodynamic advantage as the contra rotating propellers’ seven blades (four in front, three in rear) mount to a smaller torpedo than would be required for a single large, four blade propeller.

A full line of propellers in various pitches and up to 18 inches in diameter, all designed specifically for the V12 Verado outboard, is available. These propellers minimise slip, providing more rapid acceleration. The contra rotating configuration also makes docking manoeuvres easier by providing greater slow speed forward and reverse authority.

Mercury collaborated with top industry engineers to ensure that shifting — which is synchronised on multi engine configurations — is so smooth that it’s nearly imperceptible to the boat’s passengers. The hydraulic shifting mechanism eliminates “shift clunk,” providing a premium experience at slow manoeuvring speeds and while using Mercury Joystick Piloting for Outboards. The two speed transmission also contributes to unrivalled fuel economy (and, therefore, unprecedented range) and exceptionally low sound levels, especially at cruise.

 

600hp starts with a 7.4 litre quad cam V12 block.

Mercury also offer a 500hp Mercury SeaPro outboard built on the 7.6 litre V12 platform and is engineered to withstand extraordinarily demanding commercial applications around the world. The 500hp SeaPro outboard shares features and benefits of the 600hp V12 Verado outboard.

The new 7.6 litre V12 600hp Verado engine is the highest horsepower outboard ever developed by Mercury Marine and in fact, it is the highest horsepower outboard engine in production today. Its naturally aspirated, large displacement, quad cam powerhead generates incredible torque to power large centre consoles, day boats, runabouts, luxury cruisers and more.

The first pair in New Zealand were fitted to a Rayglass 12.5m Protector, with the first single installation to be mounted on the transom of an Extreme 915.  

ASTOUNDING FUEL EFFICIENCY

Mercury attacked the goal of minimising fuel burn on several fronts. A sophisticated and proprietary fuel management system, something Mercury calls Advanced Range Optimisation, adjusts fuelling automatically in accordance with operating conditions. This results in significant fuel savings, especially at cruise.

Although Pacific PowerBoat magazine didn’t get the opportunity to run full fuel and performance data on the 600hp V12, the well-respected boattest.com has performed a number of tests on 2/3/4 engine multi rigs.

Fuel consumption at maximum rpm (6400-6500) is around 190 lph per engine. Drop that back to a more sedate cruise of 4500 rpm and you can expect somewhere close to 95 lph per engine. At 3500 rpm the fuel drops to around 70 lph.

Pressing the electronic release pops open the hood, and a gas strut holds it in place.

A closed loop fuel control system uses wide range oxygen sensors to further optimise fuel mixture at all operating points and internal moving parts are protected by an advanced lubrication system designed to reduce windage and friction.

Every submerged surface of the midsection and gearcase is designed with a hydrodynamic shape to minimise drag. Plus, the contra rotating propellers provide maximum overall blade area, resulting in outstanding performance, acceleration and fuel economy.

The world’s first two-speed transmission on an outboard allows the engine’s rpm to come down at cruise — a key operating efficiency that saves fuel, extending range and running time on the water.

EASIER MAINTENANCE

Mercury built the V12 Verado outboard to make maintenance easy. This engine is capable of operating for 200 hours before requiring routine service, including oil changes, and basic maintenance can be done through the innovative top cowl service hood while the boat is still in the water. The entire cowl doesn’t need to be removed to allow more in-depth service until 1,000 hours or five years. Plus, Mercury added enhanced engine monitoring systems to improve the overall boat ownership experience.

The V12 Verado outboard delivers everything you want and more in a high-horsepower outboard.

Routine maintenance is made easy with a newly designed cowl hood providing enough access to accomplish all the maintenance tasks associated with the 200-hour service interval without having to remove the boat from the water. Much more than a service hatch, this hood operates more like the hood of a car. Pressing the electronic release pops open the hood, and a gas strut holds it in place. Engine components are neatly arranged, and the touch points are colour coded. The service infographics inside are intuitive and easy to follow.

The V12 Verado outboard is designed for use with new premium Mercury Precision Lubricants products. These include power steering fluid, automatic transmission fluid and 10W 30 full synthetic engine oil, capable of providing maximum protection through a wide range of extreme operating conditions and temperatures.

Mercury applied industry-leading science to create a remarkably quiet and smooth boating experience. New noise management designs under the cowl and in the next generation Advanced Midsection result in extraordinary sound dampening and vibration mitigation. Plus, the electronically activated shifting of the two speed transmission is smooth and quiet.

Owners of large boats will love the extra space that using outboard engines frees up. Knowing this, Mercury brought several design elements together to minimise the space occupied by the V12 Verado engine, even when it is tilted to raise the props out of the water. The engine’s space saving design ensures its compatibility with a broader array of boats.

To conserve space on the transom, the engine features a tall, narrow angle “V” engine block design. The steerable gearcase eliminates the need for spacing that would otherwise be required to pivot the entire engine for steering. These characteristics enable the V12 Verado outboard to be mounted in multi engine configurations with a minimum spacing requirement of only 689cm (27”) from engine centre to engine centre. This 600hp engine needs only slightly more space on the transom than a 300hp Verado outboard and requires less spacing than competitors’ high horsepower outboards.

ENHANCED DIGITAL CONTROLS

In addition to compatibility with the renowned Mercury Joystick Piloting for Outboards system, the V12 Verado outboard has the Next Gen Digital Throttle & Shift (DTS) system. The new controls are sleek and ergonomic. Mercury made them more intuitive by adding features like push button access to Active Trim, which automatically adjusts trim for optimal performance. A Premier dual handle console mount control for multi engine boats includes an integrated digital display that connects boaters with valuable system information and helpful pop-ups.
