SeaPro 75-150 HP

The Mercury SeaPro™ mid-range outboards take working to the next level—uncommonly powerful, uniquely compact, uncompromisingly reliable, and unbelievably fuel efficient. To maximize durability, upper mounts are twice as stiff as recreational models. The compact size of these mid-range outboards lets you refit older boats with more horsepower enabling them to perform better than ever with the latest technology. They’re the engines with the toughness and durability you need to get the job done.
Everyone wants the same things from a co-worker. Ability. Dedication. Reliability. Versatility. Anything to help the workday go smoothly. From 15hp to 500hp, the Mercury® SeaPro™ outboards are built to handle the heavy-duty needs of commercial boating applications. A job on the water can be unpredictable, with demanding hours and conditions that can change in an instant. But a SeaPro outboard clocks in on time every day, eager to work as hard as you do, as long as you do.
An easy-access fuel filter and no-spill oil-change system minimize messes and downtime. Under the cowl, a convenient decal provides an overview of routine maintenance intervals. Mercury has also simplified freshwater flushing, ensuring easy SEAPRO maintenance at the end of a long day on the water.
SeaPro engines are specifically engineered for the punishment of commercial use. Components are sized and tested to ensure strength and confidence for the long haul. For increased durability, upper mounts are twice as stiff as recreational models. A proprietary low-copper aluminum alloy, XK360, also provides superior corrosion resistance, adding peace of mind to commercial saltwater applications.
