Description

SeaPro 200-350hp

3.4L V6 and 4.6L V8

Commercial calibration meets commercial duty cycles, delivering more power with less engine stress. Unmatched corrosion resistance starts with superior aluminum alloys and coatings, plus four serviceable anodes, including one in the cylinder block. All to deliver an engine that works as hard as you do.

FEATURES

Adaptive Speed Control

Maintain engine rpm despite changes in load or conditions, with no throttle adjustment.

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.

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.

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.

SMARTCRAFT

SmartCraft. The Power To Do More.

Mercury SmartCraft® digital technologies refine the entire boating experience to ensure every day on the water reaches its full potential. From intelligent gauges and displays to advanced systems that make boat control easy, SmartCraft gives you the power to do more with your time on the water.

SmartCraft compatibility is available for Mercury engines 2004 and newer, 40hp and above; 2022 and newer, 25hp and above. Features vary based on controls and engine models.

Gauges

SmartCraft digital gauges are a convenient solution for staying in the know. They offer at-a-glance access to precise engine data and select SmartCraft controls on a compact digital interface.

Controls

Enjoy instantly responsive control and precise handling with Mercury digital control systems. Whether driving or docking, every task is made easier so you can take the helm with confidence.

Displays

With SmartCraft, you can integrate your engine with a compatible onboard display, gaining instant access to performance data and SmartCraft controls on the screen you use most.

Connectivity

The Mercury Marine app is the ultimate boating companion. It transforms your mobile device into a hub for monitoring data, connecting with a dealer and viewing helpful content.

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.

VesselView Mobile

VesselView Mobile® allows you to use a mobile device to connect wirelessly with your Mercury outboard, providing quick, convenient access to your own custom gauges, maintenance logs and performance data, like engine hours and fuel tracking.

VesselView Mobile is compatible with all current SmartCraft-capable Mercury outboards (2004 and newer, 40hp and above; 2022 and newer, 25hp and above).

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 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).

PERFORMANCE

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.

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.

87-Octane

SeaPro outboards are calibrated to deliver full performance on 87-octane fuel, while a boat-mounted water-separating fuel filter kit helps prevent fuel-related issues.

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.
