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>

Product Details

How Does Turning Point Design Industry Leading Performance Props? When Turning Point designs a new prop for a given category, they identify the best performing OEM and Aftermarket stainless steel props in the market that fits into that category. A better aluminum & stainless steel version is designed at the same time using the same geometry & drawing. Through testing, Turning Point’s engineers modify the design until it performs better than the best competitive Stainless Steel prop.

Why upgrade to a Tuning Point stainless steel propeller?
- Stainless steel propellers are much more durable compared to aluminum.
- Substantial better performance over competitive aluminum propellers. (Minimal performance difference, around 0.5-1mph speed gain over Turning Point Aluminum Propeller Designs.)
- Expect better performance over competitive OEM and Aftermarket Stainless Steel propellers.

The New Express Mach3 OS Series of Stainless Steel Propellers are the next step in the evolution of our very popular larger diameter VO series. Our Engineers and Propeller Experts made improvements to the cup, leading and trailing edges, and the aggressive progressive rake and blade geometry that are Turning Point hallmarks. These modifications have produced a propeller with excellent hole shot, impressive bow lift, and class leading cornering. The Express Mach3 OS is perfectly matched to large horsepower bay boats, offshore center consoles, and high horsepower pontoons/tri-toons. It will fit all 90hp and larger 4.75" gearcase outboards from all engine manufacturers, and Mercury® Alpha One™ and Bravo One™, and Volvo® Penta® SX sterndrives. Large diameter three blade propellers offer great mid-range fuel economy in many applications. Whether you are looking to maximize your time on the water, extend your cruise range, or just stretch your fuel dollars, the Express Mach3 OS is a great choice to get the most out of your boat.

Proprietary Stainless Steel, TP17™:
Formulated to meet the exacting requirements of the New Express Mach3 and Mach4 designs. 20% higher chromium content than the competition - more shine, better corrosion resistance. Almost 250% Stronger and 5X more durable than run-of-the-mill stainless steel. This new material allows Turning Point's Engineers and Designers the freedom to produce radical new designs that will help you wring the most performance out of your boat.

Large Free Flowing Exhaust Ports:
Turning Point's Propeller Housings have massive Exhaust flow pathways. Their Propellers have 40% more exhaust flow Area versus competive product. More exhaust flow and less backpressure can generate more horsepower. Like headers for your boat.
