Outboard Propeller for Johnson Evinrude 40-75HP Engine (Aluminum,12 1/2x13)

【13-SPLINE FITMENT ONLY】 Custom fit for Johnson/Evinrude 40-75 HP outboards with a small 3-3/8" gearcase. CRITICAL: Please physically count your prop shaft splines before ordering. This fits 13-tooth splines exclusively. 【ALUMINUM OR STAINLESS】 Choose Aluminum for a cost-effective, sacrificial gearcase defense. Upgrade to our marine-grade Stainless Steel for aggressive hole shots and maximum top-end speed in saltwater. 【PRESSED IN RUBBER HUB】Features a built-in vulcanized rubber bushing designed to absorb shift shock and intentionally slip upon hard impacts to protect your lower unit gears. 【PITCH SELECTION GUIDE】 Right-Hand (RH) rotation. Select a lower pitch (11 or 13) for heavy loads and maximum thrust. Choose a higher pitch (15 or 17) for light boats and maximum top-end cruising speed. 【OEM REPLACEMENT】 Restores factory performance. Directly replaces Aluminum OEM 763488, 763461, 778774, 763462, and Stainless Steel OEM 763896, 763897, 763898.
