More power for the job
The new Mercury SeaPro V-8 and V-6 outboard models offer more of everything: more displacement, more power, more efficiency, and more durability. The impressive strength of our new 4.6-liter V-8 and 3.4-liter V-6 engine blocks is specifically designed for commercial use. In terms of fuel efficiency, these engines perform better than ever before. With their combination of ample torque and low weight, they are ideal for heavily used boats. This engine is guaranteed to do its job – so you can do yours.

AMS
Ideal for commercial fishing boats, commercial workboats, and police boats. Available with joystick control, electrohydraulic power steering, and Mercury's AMS (Advanced MidSection). The Advanced MidSection ensures that virtually no vibrations are transmitted to the boat, while the joystick control offers maximum control and maneuverability.

CMS
The combination of Advanced Range Optimization (ARO) and fuel metering precisely adjusts the fuel mixture to ensure optimal fuel efficiency. For commercial fishing boats, commercial workboats, and police boats
