RELIABILITY, PORTABILITY, AND POWER.

RELIABILITY, PORTABILITY, AND POWER.

The new Mercury 200hp to 300hp SeaPro™ four-stroke outboards provide what you demand to get the job done - plenty of displacement, power, efficiency and durability. The impressive muscle of our new V-8 4.6-liter and V-6 3.4-liter powerheads is specifically designed for commercial duty and delivers our best-ever fuel economy. The one-two combination of ample torque and low weight makes these engines ideal for heavily loaded boats.

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.

Reliability & Durability
The V8 and V6 SeaPro outboards generate ample torque at lower rpm levels, enabling users to work their outboards hard without placing excess stress on the engine.

Lightweight & Compact
Each 200 - 300hp SeaPro CMS (Conventional Midsection) outboard is the lightest engine in its class and is built to handle the demands of commercial applications.

High Displacement
The 4.6L V8 225 - 300hp SeaPro outboards boast class-leading displacement, while the 200hp SeaPro features a brawny 3.4L V6 powerhead with plenty of muscle to get the job done.
