Mercury 25 and 30hp FourStroke outboards make light work of your biggest adventures. Quick and compact. Reliable and durable. Efficient and easy to own. FourStroke outboards bring big capabilities to small vessels.

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.
