Overview

Built for boats that earn their keep, the pre-owned 2021 Mercury 90 SeaPro Command Thrust is a commercial-grade four-stroke. Its 90 horsepower comes from a 2064 cc (2.1 L) inline-four with an eight-valve SOHC head and multi-port electronic fuel injection, and the SeaPro tune combined with the Command Thrust gearcase pairs a larger-diameter lower unit and lower 2.33:1 gearing to swing a bigger prop for serious low-speed thrust. It carries electric start, power trim and tilt and a 20-inch long shaft. Heavy pontoons, workboats and loaded hulls are exactly its element. We've inspected this SeaPro and can crate it for freight anywhere in the lower 48.
