Every day, even in the toughest conditions, SeaPro high-horsepower outboards are built to tackle the biggest jobs. They feature heavy-duty components designed to work as hard as you do, with unmatched corrosion resistance to go wherever the task takes you.
SeaPro™ 200-350hp
5.7L V10, 4.6L V8 and 3.4L V6
Intuitive, Innovative Features
Adaptive Speed Control
Maintain engine rpm despite changes in load or conditions, with no throttle adjustment.
Industry-Exclusive Battery Management Technology
When needed, the idle charge battery management system works for you by monitoring battery voltage and adjusting engine rpm at idle to boost alternator output.
Easy to Maintain
The industry-exclusive top-cowl access door eliminates hassle, allowing you to check or top off oil without removing the cowl. And gearcase oil can easily be drained from the torpedo.
Heavy Duty Gearcase
SeaPro gearcases are validated at three times the lifespan of a recreational gearcase. The V10 SeaPro engine features an all-new rugged gearcase with advanced hydrodynamics for control, efficiency and durability.
Reliability & Durability
High-horsepower SeaPro outboards generate ample torque at lower rpm levels, enabling operators to work their outboards hard without placing excess stress on the engine.
SeaPro Performance Data
Exceptionally Smooth & Quiet
Precision-tuned intake and exhaust, combined with fuel-injector covers, minimize noise for more comfortable all-day operating. V8 and V6 models are 15-30% quieter than a leading four-stroke competitor, while the V10 model is 28% quieter at cruise than a leading competitor.
Lightweight & Compact
Each SeaPro Conventional MidSection (CMS) 200-300hp model is the lightest engine in its class and is built to handle the demands of commercial applications.
High Displacement
V10 and V8 SeaPro outboards boast class-leading displacement, while the 200hp SeaPro outboard features a brawny 3.4L V6 powerhead with plenty of muscle to get the job done.
SeaPro Advantage
Efficient All-Around Performance: A host of efficiency-enhancing features such as Advanced Range Optimization (ARO), a closed-loop fuel system and a hydrodynamic gearcase optimize fuel economy so you can get more done on every tank.
Regular Unleaded (91 RON): SeaPro outboards are calibrated to deliver full performance on Regular Unleaded (91 RON) fuel, while a boat-mounted water-separating fuel filter kit helps prevent fuel-related issues.
Compact Flexibility: V10, V8 and V6 SeaPro outboards mount on 26-inch centers, making them ideal for a broad range of multi-engine applications and simple, seamless repower rigging.
High-Output Alternators: To help support a heavy load of onboard accessories, SeaPro outboards feature powerful alternators, including a 150-amp alternator on the 350hp engine.

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 more productive with SmartCraft.
Joystick Piloting for Outboards and Electric Steering
SeaPro outboards with the Advanced MidSection (standard on V10 350hp; available for V8 300hp) are compatible with Mercury Joystick Piloting for Outboards (JPO) for approved multi-engine applications as well as the latest Mercury Electric Steering system. JPO provides fingertip control to move forward, sideways or even rotate in place for easy, confident maneuvers in tight spaces. Electric Steering enhances handling and responsiveness for exceptional vessel control, particularly when using JPO. The Electric Steering system’s advanced power-saving design reduces power consumption by more than 50% over the previous electro-hydraulic steering system, leaving more power for running other onboard accessories.
Digital Throttle & Shift Controls
Standard with V10 and V8 AMS SeaPro outboards and available for V8 and V6 CMS SeaPro outboards, 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 can help make any job even easier.
Active Trim
Active Trim can help you get the job done more efficiently by automatically trimming the engine. It simplifies boat operation while improving engine performance and decreasing fuel costs. Active Trim is compatible with all SmartCraft-capable Mercury outboards (2004 and newer, 40hp and above; 2022 and newer, 25hp and above).
VesselView Mobile
With the VesselView Mobile® plug-and-play module, you’ll always know what’s happening under the cowling. It wirelessly connects your engine with a mobile app, making it easy to monitor engine data and track routine maintenance on a tablet or smartphone. VesselView Mobile is compatible with all SmartCraft-capable Mercury outboards (2004 and newer, 40hp and above; 2022 and newer, 25hp and above).
The Mercury Edge: Anti-corrosion protection
Mercury SeaPro four-stroke outboards offer superior protection against corrosion with the industry's lowest-copper aluminum alloy. And the life of critical components is extended with more stainless steel.
