1. Introduction to Mercury Marine
Mercury Marine is a name that has become the pinnacle in marine excellence. Mercury has been the leader in outboard engine technology since 1939. Mercury takes pride in manufacturing powerful, long-lasting, and user-friendly engines that withstand the ages — on fresh and saltwater lakes, rivers, and oceans.
Whether you’re a professional angler, performance boating fan, or simply a water aficionado who prefers to be out on the water for hours, Mercury has an engine that is right for you.
2. What Is “CXL” in Mercury Outboards?
Model designation is essential in selecting the right outboard motor. In Mercury 300HP CXL FourStroke, “CXL” describes a particular shaft length and counter-rotating propeller configuration.
-
C = Command Thrust gearcase for improved handling
-
XL = Extra Long shaft (25″)
-
Counter-Rotation = Created to turn in a direction opposite to normal motors, ideally suited for twin-engine installation
Thus, the CXL model is specifically intended for boats requiring improved control, larger shaft diameters, and counter-rotation operation — especially in twin engine installations.
3. Mercury 300HP CXL FourStroke Overview
