Aluminum 3blade outboard propeller, 13.25 inches diameter, 17 inch pitch. Cupped and cambered blade geometry maximizes water grip for strong acceleration, improved speed, better bow lift, and efficient overall operation. Durable cast construction and specially formulated alloys deliver long service life and consistent performance. Key benefits Better acceleration and throttle response thanks to cupped and cambered blades that bite into the water. Higher speed and improved overall efficiency from an optimized 17 inch pitch. Improved bow lift for easier trimming and better visibility while underway. Durable cast aluminum and special alloy composition resist wear and maintain shape under load for reliable operation. Direct replacement for several common OEM part numbers, simplifying repairs and maintenance. Key attributes Material: aluminum Blades: 3 Diameter: 13.25 inches Pitch: 17 inches Construction: precision castings with special alloy for durability and consistent performance Compatibility and replacements Replaces: Mercury: 4877344A45, Quicksilver: QA2036X, Evinrude/Johnson: 765183, Tohatsu: 999RUBA317M, Yamaha: 6E5459450100, Michigan: 992214, Solas: 941113317, Turning Point: 21431711 Typical applications Routine propeller replacement for small to midsize outboard engines that match the listed replacement numbers, restoring original handling and performance. Watersports and towing where stronger acceleration and improved bow lift make getting on plane easier and maintain stable trim. Fishing and cruising where efficient power transfer and reliable durability reduce fuel use and maintenance intervals. Installation notes Verify compatibility with your engine model and lower unit by checking the replacement part numbers listed above. Balance and pitch selection affect acceleration and speed. The 17 inch pitch is intended to deliver a balanced improvement in acceleration and cruising performance for compatible engines. This propeller is designed to be a directfit replacement that restores handling, responsiveness, and durability without altering the specified diameter or pitch.
