SeaPro - more power for the job

Mercury engineers strategically trimmed weight to produce some of the lightest engines in the class—by up to 30 pounds—and the powerhead configuration has been optimized to minimize size. Ideal for commercial fishing vessels, commercial workboats and law-enforcement boats.

The new Mercury SeaPro V-8 and V-6 outboard models bring more of everything to the job—more displacement, more power, more efficiency and more durability. The impressive muscle of our new 4.6-litre V-8 and 3.4-litre V-6 powerheads is specifically designed for commercial duty and delivers our best-ever fuel economy. The combination of ample torque and low weight makes these engines ideal for heavily-loaded boats. Guaranteed to do its job, so you can do yours.
