Description
Day in and day out, a 40 or 60hp SeaPro™ outboard is a co-worker you can count on. With increased performance at lower rpm, SeaPro outboards are engineered to deliver more power with less engine stress. Every job has its share of surprises, but a SeaPro outboard won’t be one of them.
High-Output Alternator
An 18-amp alternator helps keep batteries charged and electronics humming throughout the workday.
Command Thrust Gearcase
Designed to sit lower in the water and turn larger props, the Command Thrust gearcase lifts heavy boats on plane more easily and holds them there at lower speeds without impacting top speed.
Electronic Fuel Injection (EFI)
From the moment you crank the engine to the moment you drop the throttle, EFI technology responds with instant power. Surefire starting in all weather conditions. Smooth, efficient acceleration. Maximum capability.
Convenient Maintenance
Spend less time on service and more time on the clock with our no-spill oil change system, easy-access fuel filter and color-coded maintenance touch points.
Advanced Tiller
The available Mercury tiller adapts to you, not the other way around. You can reverse the grip for left- or right-handed throttling and adjust the tiller angle laterally and vertically for better leverage and control.
Powerful Torque
A high-displacement powerhead generates serious low-end torque to easily power boats on plane. More torque requires less work from the engine, for a longer service life.
Quick Acceleration
The single-overhead-cam design delivers instant acceleration and exceptional overall performance from midrange through top speed. 
Hard-Working Muscle
With a commercially validated gearcase and ample torque, 40 and 60hp SeaPro outboards make easy work of moving heavy loads.
Lighter by Design
By minimizing weight at every opportunity, Mercury delivers a performance boost to midsized boats.
Superior Control
With a choice of tiller or remote steering and compatibility with advanced SmartCraft® features such as Troll Control and Active Trim, you can optimize your engine for your needs. 
Valuable Fuel Savings
Light and efficient, SeaPro outboards help you get more done on every drop of fuel. The engine is also optimized for 87 octane for further savings at the pump.
Corrosion Resistance
Proprietary alloys. Durable coatings. A convenient freshwater flush system. Mercury builds SeaPro outboards to be tough enough to handle the elements, no matter where the work takes you.
