SeaPro 500hp
7.6L V12

Mercury redefined the way horsepower meets the water by building the first-ever V12 outboard. At 500hp, it’s our most powerful, most capable commercial outboard yet. Heavy-duty components provide rugged reliability, while a revolutionary steerable gearcase and automatic two-speed transmission deliver unrivaled handling and maneuverability. Every system is optimized to deliver outstanding fuel efficiency and simple maintenance so you can minimize expense and downtime and maximize output.

Intuitive, Innovative Features
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 Props

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.

V12 SeaPro Performance Data
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.

SeaPro Advantage

Powerful and Mighty: The 7.6L V12 powerhead delivers exceptional low-end torque, faster hole shots with heavy loads, capable top-end speeds – and nothing to hold you back.

Reduced Fuel Cost: Accomplish more on every tank with Advanced Range Optimization (ARO) calibration precisely adjusting fuel delivery for the best possible efficiency at cruise.

Corrosion Resistance: Not only are SeaPro outboards designed and built to withstand the rigors of saltwater, but they’re also backed by a two-year corrosion warranty.

Maximum Durability: The V12 SeaPro outboard features a heavy-duty gearcase validated at three times the lifespan of recreational gearcases. An advanced hydrodynamic design helps it slip efficiently through the water.

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 productive. Get smart.

Next Gen Digital Throttle & Shift

500hp SeaPro outboards come standard with Next Gen Digital Throttle & Shift (DTS) controls for ultra-smooth shifting, instantaneous throttle response as well as electro-hydraulic, automotive-style power steering that provides precision handling. Intuitive, push-button access to select SmartCraft technologies such as Active Trim are integrated with the control. A Premier DTS Electronic Remote Control (ERC) upgrade for multi-engine configurations includes a convenient display on the control that’s particularly beneficial for Joystick Piloting applications.

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.

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.

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 operate VHF systems or other onboard switching all from an intuitive touchscreen interface.

Limited Warranty

Your task list doesn’t include worrying about your equipment, which is why we engineered extreme protection into the V12 SeaPro outboard and backed it by a two-year limited warranty.

Corrosion Warranty

Hard anodized finishes on critical components do such an exceptional job of protecting the engine from corrosion and breakdown that Mercury backs the V12 SeaPro outboard with a two-year corrosion warranty.


Your time is valuable. We understand. That’s why we simplified outboard maintenance so you can spend less time under the cowl and more time on the clock. The V12 SeaPro outboard can run for an astonishing 200 hours between oil changes. It features an innovative top cowl service hood that makes servicing critical components easy from anywhere on the water without having to haul out the boat, while color-coded touch points inside speed up the process. The entire top cowl doesn’t have to come off to allow more in-depth maintenance until 1,000 hours or five years of operation. Less hassle means lower maintenance expense and downtime and more production when it counts.
