Mercury FourStroke 250-300hp
Mercury FourStroke outboard motors are incredibly powerful and efficient, and they feature a wide range of applications. Crafted for less weight and high displacement, they generate abundant torque and immediate power. And because they don’t have to work as hard as heavier engines or those with lower displacement, they make boats plane faster and accelerate better, and they provide optimal fuel efficiency at cruising speed.
Go BackFEATURES
Adaptive Speed Control
The Adaptive Speed Control feature lets you maintain engine rpm despite changes in load or conditions. Climbing large swells is easier. Cruising at low speeds is smoother. Carving out tight turns is effortless.
Easy to maintain
The exclusive top cowl service door simplifies routine maintenance, letting you check or add engine oil without removing the top cowl. An hour-based maintenance schedule decal is located under the cowl, providing a quick overview of routine maintenance.
Industry-exclusive battery management technology
When needed, the idle charge battery management system works for you by monitoring battery voltage and adjusting engine rpm at idle to boost alternator output.
Smooth and quiet
Featuring a large muffler and a vibration-dampening cowl design, Mercury V8 fourstroke outboards deliver an exceptionally smooth, quiet ride at any speed.
Ample charging output
A powerful alternator delivers 85 amps of charging power at wide-open throttle – perfect for keeping onboard electronics running long into the fun.
PERFORMANCE
Exceptionally smooth and quiet
The V8 300hp fourstroke outboard is 33% quieter at cruise with 30% less transmitted vibration at idle than the leading four-stroke competitor.
High displacement
The high-displacement, quad-cam design of the V8 fourstroke powerhead generates serious torque, especially at mid-range, for quick acceleration and exciting speeds.
Light and compact
The V8 300hp fourstroke outboard is the lightest in the 300hp class by more than 20 pounds. Both V8 models mount on 26-inch centres for easy repowering or new installation on a wide range of boats.
