Description
SeaPro – the right partner for the job
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.
Features
- Advanced Range Optimization (ARO) and closed-loop fuel control work together to precisely adjust the fuel mixture for optimal fuel economy. For commercial fishing vessels, commercial workboats and law-enforcement boats.
- Harsh conditions can’t deter SeaPro: TowBoatUS and commercial boat builders turn to Mercury Marine’s SeaPro engines because they’re engineered to deliver longer engine life while maintaining the power and performance necessary to get the job done.
- The Mercury Edge: Anti-corrosion protection: Mercury SeaPro four-stroke outboards offer superior protection against corrosion with the industry's lowest-copper aluminum alloy. And the life of critical components is extended with more stainless steel.
