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.

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.

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 makes boating easier by automatically trimming your outboard. It simplifies boat operation while improving engine performance and decreasing fuel costs.

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