Mercury Sea Pro line expands: V-8 225, 250, 300hp models


Mercury Marine has announced the expansion of its SeaPro family of commercial outboard engines with two new V-8 4.6L models. Building on the launch of the V-6 200hp SeaPro in February at the 2018 Miami International Boat Show, the new 225hp, 250hp and 300hp V-8 SeaPro engines bring the durability, reliability and efficiency that the SeaPro brand is known for.
“The commercial market is very important to us around the world and these engines fill out the pipeline of higher horsepower commercial outboards that our customers have been asking for,” said Tim Reid, Mercury Marine vice president of product development and engineering.” These new engines now give Mercury a full lineup of four-stroke commercial engines from 40 to 300hp.
Mercury’s new 225-300hp SeaPro FourStroke engines are designed to offer higher displacement at a lighter weight than competitor models; in fact, each of the Conventional MidSection (CMS) SeaPro V-8 models is the lightest in its class.  “Mercury has calibrated the new V8 SeaPro models to produce plenty of torque at lower rpm levels, enabling users to work their outboards hard without placing excess stress on the engine, while their exceptionally compact, lightweight design and Advanced Range Optimization (ARO) maximize fuel economy at cruise.
True to SeaPro’s workhorse heritage, the new V-8 225-300hp SeaPro models are engineered to deliver years of trouble-free performance. They are manufactured with heavy-duty components to cope with the demands of global commercial operation – including a gearcase that is validated at three times the lifespan of a recreational gearcase.
Advanced MidSection (AMS)
The new V-8 300hp SeaPro is available with Mercury’s exclusive Advanced MidSection (AMS), which moves engine mounts aft and outward to virtually eliminate vibration from being transmitted to the boat. In fact, transmitted vibration is a whopping 60% less than the leading competitor’s 300hp engine. Models equipped with the AMS also feature electro-hydraulic power steering and are compatible with Mercury’s Joystick Piloting system, which provides maximum control and maneuverability in multi-engine applications
