Turning Point Propellers

<h3>About Turning Point Propellers</h3><p>Founded in 1997 and headquartered in Jacksonville, Florida, <strong>Turning Point Propellers</strong> has spent more than 26 years doing one thing exceptionally well: engineering boat propellers that outperform the competition. From recreational day boaters to demanding offshore anglers, Turning Point has built a reputation as a go-to source for high-performance aluminum and stainless steel propellers designed to maximize speed, handling, and fuel efficiency on the water.</p><p>Turning Point's philosophy is straightforward — leverage cutting-edge metallurgy, advanced casting technologies, and aggressive blade geometry to produce the best-performing propeller in every category. The result is a lineup that covers everything from small outboards to high-horsepower sterndrive applications, with <a href="/7621-turning-point-propellers-propeller-parts-accessories-202388">propeller parts and accessories</a> rounding out the ecosystem for boaters who want a complete solution.</p><h3>Flagship Product Lines</h3><p>Two series anchor the Turning Point lineup. The <strong>Hustler Series</strong> aluminum propellers are manufactured using an exclusive squeeze-cast process that produces a tighter grain structure, stiffer blades, and resistance to flex — delivering stainless-steel-like performance at an aluminum price point. A proprietary five-step powder coating process adds a uniform, corrosion-resistant finish that stands up to years of saltwater exposure.</p><p>The <strong>Express Series</strong> stainless steel propellers push performance even further. Vented barrels allow exhaust gases to escape during acceleration, reducing water density around the blades and enabling faster hole shots. The Express Mach4's patented Dual Geometry blade design — featuring two different blade shapes in a single propeller — delivers unmatched acceleration and cornering without sacrificing top-end speed. <a href="/7621-turning-point-propellers-quicksilver-propellers-202408">Quicksilver-compatible propellers</a> from Turning Point give Mercury engine owners a compelling high-performance alternative, as the Express and Hustler lines are engineered to fit a broad range of Mercury outboards and sterndrives.</p><h3>MasterGuard Hub System</h3><p>One of Turning Point's most celebrated innovations is the <strong>MasterGuard Hub System</strong> — the first interchangeable hub system ever introduced to the propeller market. Using a patented one-piece design with glass-filled nylon over brass splines, it eliminates the failure points common in traditional sleeve-and-spline and pressed-rubber hub systems. A high-tech polymer cushion absorbs shift shock and impact energy, protecting the engine and drivetrain. MasterGuard hubs carry an industry-leading lifetime warranty and are cross-compatible with Mercury Flo-Torq II, Michigan Wheel XHS, and Solas Rubex hub systems, making them ideal for boaters looking to upgrade without replacing existing hardware.</p><h3>Broad Engine Compatibility</h3><p>Turning Point propellers are engineered to fit engines from virtually every major outboard and sterndrive manufacturer, including Yamaha, Honda, Suzuki, Evinrude, Johnson, OMC, Volvo Penta, Tohatsu, and Mercury. Whether you're shopping for <a href="/7621-turning-point-propellers-acme-propellers-201593">ACME-spline propellers</a> for an inboard or sterndrive application or seeking a direct Quicksilver replacement, Turning Point has a prop to match. Their 500 and 700 Series hub kits further simplify cross-compatibility across 4.25&quot; and 4.75&quot; gearcase sizes.</p><h3>Why Boaters Trust Turning Point</h3><ul><li>Squeeze-cast aluminum and TP17 stainless steel construction for maximum blade strength</li><li>Up to 46% more reverse thrust over competing propeller designs</li><li>Patented Dual Geometry blade design for 4-blade performance without speed loss</li><li>Industry-leading MasterGuard lifetime warranty on hub kits</li><li>Five-step Ultra-Coat powder coating for superior corrosion and impact resistance</li><li>Global distribution network with dealer and OEM partnerships worldwide</li></ul><p>Whether you're chasing top speed on a bass boat, pulling watersports tubes on a pontoon, or navigating offshore swells on a center console, Turning Point Propellers delivers the engineering depth and product breadth to keep your boat performing at its best.</p>
