Caterpillar Ships First C8.7 Diesels
Caterpillar Marine has announced the first shipments of the new Cat C8.7 supercharged diesel engines. The electronically-controlled C8.7 is capable of delivering 650mhp at 2300 RPMs while meeting updated EPA standards.
The C8.7’s sophisticated fuel delivery system allows the use of a radial belt-driven supercharger in addition to a conventional turbocharger; this feature eliminates smoke and reduces lugging while delivering phenomenal low-end torque and impressive fuel economy. Once the supercharger is no longer needed as the turbo takes over the boost function, an electromagnetic clutch disengages the supercharger and allows the turbo to provide the maximum boost pressure. This renders the new engine impervious to turbocharger lag and allows rapid transient response throughout the engine’s operating range. Along with traditional shaft installations, the C8.7 is also designed to be integrated with the Cat Three60 Pod 650. For more information, visit www.caterpillar.com.
Mercury Unveils 400hp Verado
At a staggering 153 horsepower per liter, the all-new Mercury Racing Verado 400R outboard is the most powerful consumer outboard ever produced by Mercury. This incredible achievement in power and efficiency was achieved through a number of advancements to the proven 2.6L Verado platform, including a custom cold air induction system and an all-new water-cooled supercharger that’s designed to reduce intake temperatures and significantly increase air density. This enables the engine to generate unprecedented torque and unmatched acceleration all the way from the lower end of the power band up to the 7,000 RPM maximum engine speed. Electronic knock control enables the engine to safely run on 89 octane fuel when the recommended premium 91-octane fuel is not available. The 400R is the first Verado to feature the race-proven Sport Master gearcase with low-water pickups for added performance and is also the first Mercury Racing outboard to feature Joystick Piloting for Outboards (JPO) technology.

Even Higher Horses: Seven Marine’s 627
Seven Marine was founded in 2010 by a team of proven innovators with decades of experience in the marine marketplace. Every engineer and technician has been hand-picked for their expertise, ingenuity and accomplishements, and the entire team is focused only on making the most powerful and technologically advanced, highest-performing outboard motors on the planet. With their 557hp model they claimed the title as the most powerful outboard but now the team has unveiled an even larger one: the stunning 627. Loaded with technical features, as well as aesthetic innovation such as integral LED lighting that provides a dramatic look, the 627 claims the record as the world’s highest-horsepower outboard motor and should prove to be a great alterative for today’s ever-larger center consoles.

More from MAN
In keeping with their motto of ‘reliable and efficient,’ MAN has introduced a newly developed 12-cylinder V-engine. The German engine manufacturer will extend the power range of its high-speed marine engines for heavy-duty operation up to 1,000 hp. By adapting the turbocharger and the valve timing, MAN was able to raise the mean pressure and increase the power rating compared to the most powerful engines available. The new, efficient MAN offers an excellent power density for heavy-duty applications. Individually mounted cylinder heads also ensure ease of service, which allows MAN’s solid power unit to shine when it comes to cost-effectiveness calculations. All MAN marine engines also available in EPA Tier 3. For more information visit www.man.eu.
