Information

2025 Mercury Marine® SeaPro 40 hp

Engineered for Commercial Duty

Season after season, these durable, easy-to-maintain SeaPro™ commercial outboards deliver reliable starts and improved fuel efficiency. By generating serious torque at low rpm, they provide more power with less stress on the engine. Get on plane faster – and stay there longer at lower speeds.

A compact, single-overhead-cam design and long piston stroke deliver more low-end torque for stout power, even when pushing a heavy load. For commercial fishing vessels, commercial workboats and law-enforcement boats.
