A powerful alternator – 35 amps on the 115hp outboards – helps keep batteries charged and electronics running throughout the workday.
Heavy-Duty Gearcase
The 115hp outboards feature the hard-working Command Thrust gearcase. It’s designed to turn larger props, which helps lift heavy boats on plane more easily.
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.
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 8-valve, single-overhead-cam design delivers rapid acceleration and exceptional overall performance from midrange through top speed.
Lighter by Design
By minimizing weight at every opportunity, Mercury delivers a performance boost. The 115 SeaPro engines are also the lightest outboards in their class.
Durability in the Details
With a commercially validated gearcase and upper motor mounts designed to be two times stiffer than on recreational models, SeaPro outboards are perfectly suited to handle the rigors of commercial duty.
Valuable Fuel Savings
Light and efficient, SeaPro outboards help you get more done on every drop of fuel. They’re also optimized to deliver full performance with 87-octane fuel 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.
Superior Control
With a choice of tiller or remote steering and compatibility with advanced SmartCraft® features such as Troll Control and Active Trim, SeaPro outboards let you optimize your propulsion system for your needs.
