V12 Power and Performance

The outboard segment’s first V12 powerhead delivers uncompromising strength and reliability for commercial operators. Its 7.6-liter displacement and quad-cam design generate superior torque to easily power big boats on plane and move heavy loads.

Automatic Two-Speed Transmission

The two-speed transmission makes easy work of transferring 500hp to the gearcase. It delivers maximum torque and acceleration in first gear to power heavy boats on plane quickly before the transmission silently shifts to second. No shift clunk. No limitations. Only smooth, efficient power.

Independent, Steerable Gearcase

Electro-hydraulic controls allow the steerable gearcase to react instantly to operator commands. With no movement from the engine above water, there are no distractions – only precise maneuverability in close quarters and effortless handling in open water.

Contra-Rotating Propellers

A new series of dual props were expertly crafted to harness the full potential of 500hp. Designed to run in a contra-rotating configuration, the new propellers power heavy boats on plane swiftly and efficiently, while delivering exceptional handling at low speeds and optimal fuel economy at cruise.

Exceptionally Smooth & Quiet

A more rugged, more refined next-generation Advanced MidSection (AMS) mounting system cradles the powerhead to isolate noise and vibration, while careful tuning dampens induction sounds and nearly eliminates injection noise.

Superior Fuel Economy

The V12 SeaPro outboard is calibrated to deliver full performance on 87-octane fuel, with a host of efficiency-enhancing features such as a hydrodynamic gearcase and Advanced Range Optimization (ARO), which automatically adjusts fuel deliver to maximize economy and reduce your fuel expense.

Refined Power

The highest displacement of any commercial outboard – 7.6 liters – means more torque and more horsepower, with less stress placed on the engine. That translates to a longer service life and more reliable performance, so you can accomplish more.

Quiet & Smooth

With characteristics developed for the legendary Mercury Verado engine family, the V12 SeaPro outboard establishes a new benchmark for smooth and quiet operation among commercial outboards. It’s quiet at idle and cruise, with significantly less vibration.

SmartCraft® The Power to Do More

SmartCraft® is a full suite of digital technologies, fully integrated and totally coordinated. Gauges, sensors, vessel systems, computer-controlled features – one total package, one high level of control. Make your boating experience easier, safer and a lot more enjoyable.

Mercury SeaPro 500hp Next Gen Digital Throttle & Shift

Digital Throttle & Shift (DTS) controls deliver smooth, quiet shifting and instant throttle response, with zero hesitation. With integrated SmartCraft technologies and an intuitive user interface, DTS puts you in complete command of your adventures.

Mercury SeaPro 500hp Joystick Piloting for Outboards

Slow-speed handling has never been easier now that the industry’s most advanced Joystick Piloting system – available for multi-engine configurations with up to six SeaPro outboards – is operating alongside a steerable gearcase, two-speed transmission and dual props. The engines stay still, while their gearcases turn underwater, making it possible to orchestrate close-quarter maneuvers with unparalleled deft and precision.

Mercury SeaPro 500hp Skyhook Advanced Features

Joystick Piloting includes access to Mercury Skyhook® Advanced Features, which allow you to “digitally anchor” the boat in current, set and maintain a heading, lock the bow in place or line up accurate drifts. Just punch a button, and the system goes to work. Adjustments are subtle, with no shift clunk, and they’re smooth thanks to the steerable gearcase, which eliminates distracting engine movement above the water.

Mercury SeaPro 500hp VesselView

Available VesselView® displays transform the helm of the boat into the ultimate command center by linking together the Mercury propulsion system with compatible onboard accessories. You can monitor engine data, control SmartCraft digital technologies, view charts and sonar, and even operate onboard entertainment systems all from an intuitive touchscreen interface.
