In determining boat performance, propellers are second in importance only to the power available from the engine itself. Without the propeller’s thrust, nothing happens. Your boat’s propeller affects every phase of performance-handling, riding, comfort, speed, acceleration, engine life, fuel economy and safety.
Like tires on a car, the propeller conducts the power from the engine to the "road." Your propeller is the primary connection between your engine and the water. Which propeller or propellers you select to make that connection is critical to achieving optimum boat performance.
We prepared this web site to help you make that choice wisely. We’ll show you how a marine propeller works, and how engine and boat performance are directly related to the propeller. Because propellers are vital to engine performance, Mercury Marine® manufactures over 500 different and distinct Mercury Propellers® for Mercury® Outboards and MerCruiser® Sterndrives. These range from the simplest plastic propellers for electronic trolling motors to the blueprinted, custom-tuned Mercury Hi-Performance/Racing propellers. Each propeller is designed to maximize the performance return available from a specific engine or group of engines. We can assure this only through designing, engineering and manufacturing our own propellers - over half a million a year - at dedicated facilities. Our engineering staff is the industry’s most experienced in propeller design and innovation.
This site has been compiled from engineering data and factual engine and boat test results obtained from our on-the-water test sites. This information represents the latest technology for marine pleasure boat and racing propellers. This site is designed to provide even the novice boater a solid understanding of propellers. However, some of the information presented here is also very technical. So, if you have questions or need assistance in propeller selection, contact your local Mercury Outboard or MerCruiser Sterndrive dealer.
