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 earning a reputation as one of the marine industry&apos;s most innovative propeller manufacturers. What started as a drive to engineer better-performing boat props has grown into a globally distributed brand trusted by recreational boaters, dealers, and OEM partners alike. The company&apos;s core philosophy is straightforward: <em>Run Faster. Pull Harder. Handle Better.</em></p><h3>A Legacy Built on Industry Firsts</h3><p>Turning Point&apos;s history reads like a timeline of marine propulsion innovation. The brand introduced the industry&apos;s first multi-manufacturer interchangeable hub propeller, the first full-color prop selection charts, and the first online Prop Wizard calculator to help boaters match the right prop to their engine. Later milestones include the first high-performance four-blade aluminum propeller and the first &ldquo;safer&rdquo; propeller design — the Aegis series — engineered to minimize harm to marine life at low boat speeds.</p><p>Today, Turning Point&apos;s lineup is organized around three flagship series: the <strong>Hustler</strong> aluminum propellers, the <strong>Express</strong> stainless steel propellers, and the <strong>Aegis</strong> safer-design series. Each is built to cover a wide spectrum of engine outputs, from small outboards in the 6 HP range up to powerplants exceeding 300 HP, and fits vessels ranging from bay boats and pontoons to tritoons and sterndrive applications.</p><h3>Engineering That Sets Turning Point Apart</h3><p>A key differentiator in Turning Point&apos;s manufacturing process is its exclusive squeeze-cast method for aluminum propellers. This technique virtually eliminates the voids and air pockets that weaken conventionally cast props, producing a tighter grain structure and stiffer blades that resist flex — translating directly into more efficient power transfer. Stainless steel Express props feature advanced pitch-line and rake-line cupping along with vented barrels that allow exhaust gases to escape during acceleration, improving hole-shot performance. Turning Point also applies a proprietary Ultracoat powder-coat finish to all aluminum propellers for a corrosion-resistant, high-gloss appearance that holds up in harsh saltwater and freshwater environments alike.</p><h3>Propellers for Every Boater</h3><p>The heart of the Turning Point catalog is its broad selection of <a href="/200673-propellers-turning-point-propellers-7621">Turning Point Propellers</a> — three- and four-blade designs in both aluminum and stainless steel, available in right- and left-hand rotation to suit virtually any outboard or sterndrive configuration. Whether you&apos;re looking to maximize top speed, improve fuel economy on long cruises, or gain better low-end pulling power for watersports, there is a Turning Point prop engineered for that purpose.</p><p>Equally important to a proper propeller installation is the hardware that supports it. Turning Point&apos;s line of <a href="/7621-turning-point-propellers-propeller-parts-accessories-200817">Propeller Parts &amp; Accessories</a> — including their patented MasterGuard hub kits — rounds out the system. The MasterGuard hub features a one-piece glass-filled nylon over brass spline design that eliminates the failures common in older multi-part sleeve-and-spline systems, while protecting engines and drives from shift shock and impact loads. Crucially, these hub kits are covered by the industry&apos;s only lifetime warranty and are compatible with Mercury Flo-Torq II, Michigan Wheel XHS, and Solas Rubex hub kit systems.</p><h3>Why Boaters Choose Turning Point</h3><ul style="list-style:disc"><li>Over 26 years of dedicated marine propeller engineering and manufacturing</li><li>Exclusive squeeze-cast aluminum process for stronger, flex-resistant blades</li><li>Industry-first interchangeable MasterGuard hub system with a lifetime warranty</li><li>Wide compatibility across major outboard and sterndrive engine brands</li><li>Prop Wizard tool to help boaters select the optimal pitch and diameter</li><li>Vertically integrated manufacturing from raw ingot to finished product</li></ul>
