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

The Turning Point Express Mach3 OS 31511310 is a high-performance 3-blade stainless steel propeller designed for large horsepower outboards and sterndrives. Featuring a 15.6-inch diameter and 13-inch pitch with right-hand rotation, this propeller is engineered to deliver exceptional hole shot, impressive bow lift, and class-leading cornering performance for bay boats, offshore center consoles, and high-horsepower pontoons.

Advanced Design & Engineering:

The Express Mach3 OS represents the evolution of Turning Point's popular larger diameter VO series, with refined cup geometry, optimized leading and trailing edges, and aggressive progressive rake. These enhancements produce superior acceleration, improved bow lift, and excellent fuel economy in mid-range operation, making it ideal for boaters looking to maximize time on the water while stretching fuel dollars.

TP17™ Proprietary Stainless Steel:

Constructed from Turning Point's exclusive TP17™ stainless steel alloy, this propeller features 20% higher chromium content than competitive props for enhanced corrosion resistance and superior shine. The material is almost 250% stronger and 5 times more durable than standard stainless steel, allowing for radical blade designs that extract maximum performance from your engine.

Key Features:

  • 15.6-inch diameter x 13-inch pitch, 3-blade design
  • Right-hand rotation (standard)
  • Fits 4.75-inch gearcase outboards 90hp and larger
  • Compatible with Mercury Alpha One and Bravo One, Volvo Penta SX sterndrives
  • Large free-flowing exhaust ports with 40% more flow area than competitors
  • Performance-tuned pitch, rake angles, and exhaust vents
  • Excellent hole shot and bow lift characteristics
  • Superior mid-range fuel economy
  • Class-leading cornering performance
  • Universal fit for COX, Evinrude, Honda, Johnson, Mariner, Mercury, MerCruiser, Nissan, OMC, OXE, Parsun, Suzuki, Tohatsu, Volvo Penta, and Yamaha engines

Installation Requirements:

Requires Turning Point 500 series hub kit for applications under 200hp or 700 series hub kit for engines 200hp and above (sold separately). Consult application chart for specific hub kit requirements for your engine.

Ideal for boaters seeking professional-grade performance, enhanced durability, and improved fuel efficiency from their propulsion system.
