🚤 High-Strength Aluminum Propeller for Mercury Outboard Motors – 3-Blade Replacement for 5HP to 300HP
If you are looking for a reliable, affordable replacement propeller for your Mercury outboard, this high-strength aluminum 3-blade propeller is exactly what you need. Whether you are running a small 5hp engine on a dinghy or a powerful 300hp motor on a larger fishing boat, there is a specific size and pitch option designed to match your engine's specifications. These props are built with a reinforced hub and a precision-machined brass spline sleeve for a secure fit and smooth power transfer. Featuring a tough black powder-coated finish, they stand up to normal wear and tear from sand, mud, and debris, giving you consistent performance without the high cost of an OEM part.
⚙️ Key Features of These Mercury Aluminum Propellers
- Precision Fit for Mercury Outboard Engines: Specifically engineered to fit Mercury's shaft splines. Whether you have an older 2-stroke or a newer 4-stroke motor, you can find the correct 10-tooth, 12-tooth, 13-tooth, 14-tooth, 15-tooth, or 19-tooth hub to match your exact model.
- High-Strength Aluminum Alloy Construction: Made from durable aluminum alloy that resists impact damage better than brittle plastics. It provides a good balance of weight, strength, and cost, making it a practical choice for everyday boaters.
- Thickened Blades with Brass Inner Sleeve: The blades are thickened at the root for added strength, reducing the risk of bending or cracking. The center hub features a brass sleeve for smooth rotation and reduced wear on your motor's splined shaft.
- Wide Range of Pitches & Horsepower Options: From small 7.8" x 8" props for 5HP/6HP engines all the way up to 15" x 17" for 90-150HP motors. Each variant is matched to a specific horsepower range, making it easy to find the perfect replacement or spare propeller.
- Black Matte Finish for Corrosion Resistance: The durable matte black coating helps protect the aluminum from the elements, keeping the propeller looking good and performing well even after regular use in saltwater or freshwater.

❓ Frequently Asked Questions About Mercury Aluminum Propellers
How do I know which propeller tooth count and pitch I need for my Mercury outboard?
You can usually find this information in your outboard motor's owner's manual. 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.
What is the difference between the standard aluminum prop and the stainless steel version for Mercury?
Aluminum 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.
Will this propeller fit my Mercury 60HP Bigfoot or 60HP 4-stroke?
Yes, 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.
Can I use this aluminum prop on my older Mercury 25HP 2-stroke outboard?
Yes. 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. Please verify you have a 10-tooth shaft before ordering.
Does the propeller come with the necessary nut and cotter pin for installation?
No, the prop nut, thrust washer, and cotter pin are not included. You should reuse the hardware from your existing propeller or purchase new genuine Mercury hardware. We recommend applying marine grease to the splines before installation to prevent corrosion and seizing.
