MERCURY PROPELLER KEY 17-815111Q02

As soon as you spend some time at sea, you quickly realize that it’s not just the engine’s roar that makes the boat move, but the propeller, quietly working beneath the surface. It’s the propeller that transmits power and gets the hull moving. Everyone has felt that moment when real force kicks in—when the propeller engages and the boat surges forward. Like an invisible hand, the propeller transforms the engine’s raw power into true sailing pleasure. Too often considered a mere spare part, it deserves your full attention. Whether you're a weekend sailor, a passionate angler, or a professional mariner, choosing the right propeller changes everything: glide sensation, boat responsiveness, fuel efficiency, the style of your craft, and even the equipment cost. At DAM Marine, we don't just offer a wide range of products. We share our insights, advice, and tips to help every boat find the propeller that fits.
The propeller plays a central role in your boat's performance. Even with the latest engine, without the right propeller, power is wasted. It creates the link between mechanics and water: as it spins, its blades bite into the water and push it backward, propelling the boat forward. Behind that movement lies a subtle balance: each rotation turns engine energy into forward motion. Replacing your propeller isn't just routine maintenance—it can be an opportunity to rediscover the joy of boating, improve boat behavior, and boost comfort or performance. With the right propeller, your boat becomes reactive and enjoyable—the difference is clear as soon as you’re underway.
The pitch is the distance a propeller would move the boat forward in one revolution. A higher pitch means more speed—great for those who love fast cruising. A lower pitch boosts acceleration—ideal for waterskiing or quick takeoffs. This adjustment directly impacts engine RPM: too high, the engine struggles; too low, it overrevs. In practice, each inch of pitch added lowers RPM by 150 to 200 RPM. And don’t forget about slip: in real-world conditions, you naturally lose around 10 to 15% of theoretical progress.
The diameter refers to the imaginary circle formed by the blade tips. The wider it is, the more water it displaces and torque it transfers—but it also demands more engine power. So it’s essential to strike the right balance, depending on your engine's power and clearance beneath the anti-cavitation plate. Heavier boats may even require special gearcases to accommodate larger propellers for added control and thrust. Before purchasing, check whether your propeller is left-hand or right-hand rotation.
Most boat propellers have three blades, offering good performance and fuel efficiency. Opting for four or five blades boosts thrust, tracking, and reduces vibration—but top speed may drop slightly. Sailboats often use two-blade folding props to minimize drag under sail. Heavier boats and submarines might use six or seven blades for more thrust or stealth. Each application has its best option.
Aluminum suits small engines: affordable, easily replaceable, and it bends rather than breaks on impact, helping avoid severe damage. Stainless steel is stronger and more durable, especially for powerful motors or frequent saltwater use. It resists rust and minor abrasions. Bronze is rare and used for specific boats. Low-power engines might use plastic props, which are cheap and light but not recommended for heavy use.
It all starts with your activity: relaxed fishing, family cruising, or tow sports? Each use has its demands. The propeller must match the engine specifications (brand, power, type, year, splines) and hull profile (displacement or planing). At DAM Marine, we cover all major brands: Yamaha, Mercury Mercruiser, Honda, Suzuki, Evinrude, Volvo Penta and more.
The “cup” is a small tweak with big impact: a curved lip on the blade’s trailing edge. It improves grip, reduces ventilation and cavitation, and enhances acceleration. It’s a real asset for outboards and heavy boats.
Rake is the angle of the blade relative to the hub. More rake lifts the bow, aiding planing and improving performance. In leisure boating, rake ranges from 0 to 20°, but racers go up to 30°.
The hub is the central cylindrical part connecting the blades and usually showing the propeller specs. There are two main types:
These are a boater’s worst enemies. Fortunately, features like the cup help reduce these effects.
At DAM Marine, we don’t just offer a catalog. We provide a carefully curated selection of propellers in aluminum, stainless steel, or plastic, for all engines, gas or diesel, and all boats. Need accessories? We also supply all spare parts needed for propulsion, from gear kits to complete drives. Cones, nuts, hydrolube bushings, hub kits Flo-Torq, washers—it’s all there. Our top-quality product catalog covers every need, whether it’s for an engine, a gearcase, or an aluminum propeller. Our passionate and experienced team is here to guide you in finding the propeller that makes a real difference—whether for a replacement or performance upgrade. Search by dimensions, part number, large inventory, fast shipping, secure payments, easy returns: everything is designed to make your experience as smooth as your navigation.
You might think choosing a propeller is just about numbers, inches, and millimeters. But selecting the right propeller is more than specs or tech: it’s your guarantee of safe, enjoyable boating. For us, every piece of advice and every selected product serves the same goal: helping you make the most of your time at sea, with no bad surprises. At DAM Marine, we share your passion and understand your expectations. Want peace of mind? We’re here to help you find the perfect propeller to simplify your boating life. Enjoy the sea—we’ll take care of the rest.

Works with 500 or 700 series hub systems to be added at time of purchase.
Our new four-blade design is a unique design with two different blade geometries: two blades utilize the variable rake and progressive pitch of the Hustler 3-blade to achieve fast planing and incredible stability in turns, and the other two blades have a 'cleaver' design to achieve high speeds.
The result of this combination results in the highest performing aluminum propeller on the market, unmatched in turns, acceleration, boat stability and top speed.
It is the ultimate propeller for water activities (wakeboarding, tubing, water skiing, etc.), but it also offers top speed performance to boaters that no other 4-blade propeller can achieve.
