SeaPro 200-300hp Outboards 

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 V8 4.6-liter and V6 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.
