Seven Marine has positioned the 557 squarely between comparably
powerful inboard set-ups and multiple outboard riggings. The
Seven Marine 557 revolutionizes the market by creating for the
first time an opportunity for enthusiasts to experience the power,
refinement, features, and conveniences previously exclusive to inboard,
luxury sport yachts, but with all the performance, efficiency, and
ease of use inherent to outboards.
While inboards routinely pump out more than 500 horsepower, outboard
enthusiasts looking to go as far as possible, as fast as possible,
have until now been stuck with one option: rig a boat with multiple
low-output motors, and the associated weight, drag, and hassles of
servicing three or more motors.
Seven Marine is proud to change all of this by bringing to market
the most powerful outboard on the planet. Thanks to its unprecedented
557 horsepower and myriad technological "firsts," the Seven Marine 557,
with its General Motors supercharged LSA V8 (Cadillac CTS-V, Camaro ZL1),
stands boldly alone in the outboard market.
SUPERCHARGED SMALL-BLOCK V8
Seven Marine brings the Cadillac CTS-V's lightweight,
all-aluminum, fuel-injected, supercharged LSA V8
to the marine market.
NEARLY 60% MORE POWERFUL THAN
ANY OTHER OUTBOARD
The 557 horsepower supercharged V8 delivers nearly 60%
more power than any other outboard on the market.
This allows boats to be rigged with fewer motors,
decreasing weight and drag while increasing high-speed
fuel economy and offering higher available top speeds.
PERFORMANCE THROUGH TECHNOLOGY
Closed-loop cooling, an ECU-controlled octane scaler, and
dual 3.5" exhaust are among the myriad technological
advances Seven Marine has brought to the outboard market.
