You can also remove your current prop and count the splines inside the hub. The pitch is stamped on the side of your existing propeller (e.g., 10.3x12 means 10.3 diameter and 12 pitch). If you are unsure, you can message us with your exact Mercury model and horsepower for a recommendation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cspan class=\"faq-question\"\u003eWhat is the difference between the standard aluminum prop and the stainless steel version for Mercury?\u003c\/span\u003e\n\u003cp class=\"faq-answer\"\u003eAluminum is lighter, more affordable, and easier on the lower unit if you hit a rock or log because the prop will bend or break before damaging the gearcase. Stainless steel is much stronger, allows for thinner and more efficient blade designs, and costs significantly more. For general boating and casual fishing, aluminum is the practical choice.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cspan class=\"faq-question\"\u003eWill this propeller fit my Mercury 60HP Bigfoot or 60HP 4-stroke?\u003c\/span\u003e\n\u003cp class=\"faq-answer\"\u003eYes, we have a specific variant for Mercury 60HP to 140HP engines. Select the \"Water Star 60-140HP 15T\" option, and choose your preferred pitch (15 inch or 17 inch) from the dropdown menu. This variant uses a 15-tooth spline and is designed for that horsepower range.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cspan class=\"faq-question\"\u003eCan I use this aluminum prop on my older Mercury 25HP 2-stroke outboard?\u003c\/span\u003e\n\u003cp class=\"faq-answer\"\u003eYes. We have a dedicated listing for \"Mercury Old Style 25\/30HP 10T\" with 11, 12, and 13-inch pitch options. This fits the older 25HP and 30HP 2-stroke Mercury engines with a 10-tooth spline shaft.

You should reuse the hardware from your existing propeller or purchase new genuine Mercury hardware.
