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 Mach4 propeller combines innovative dual geometry blade design with premium stainless steel construction to deliver exceptional performance for outboard engines from 90-300+ horsepower with 4.75-inch gearcases. This left-hand rotation propeller features a 14.5-inch diameter and 17-inch pitch, engineered to provide the advantages of a 4-blade design without sacrificing top-end speed.

Key Features:

  • Dual geometry 4-blade design maintains 3-blade top-end speed while improving acceleration and handling
  • 14.5-inch diameter with 17-inch pitch, left-hand rotation
  • Premium stainless steel construction with enhanced corrosion resistance
  • Compatible with 90-300+ HP engines equipped with 4.75-inch gearcases
  • Unprecedented hole shot performance and lift characteristics
  • Superior rough water stability and ease of steering
  • Lifts boats higher out of the water for improved planing efficiency
  • High-gloss finish with advanced casting technology

The Express Mach4 series represents a breakthrough in propeller technology, delivering the quick acceleration and superior handling traditionally associated with 4-blade propellers while maintaining the cruising speed typically found only in 3-blade designs. This makes it an ideal choice for boaters who refuse to compromise between performance categories.

awesome price, quick shipping, great service. will definitley use them again!

So far everything is good. Price is good

Thier site was very easy to navigate and allowed me to search for parts just for my truck. Once I found the part, I happy to see the price was very reasonable and even a little bit cheaper than other sites. I was happy to see that I could check out with my amazon account. Shipping was prompt.

I bought 2 pairs of Stainless Steel polished 12x16 mud flaps. I looked at quite a few mud flaps for my Escalade EXT, and these were the only ones I could find that were not plastic or rubber. They are excellent, heavy duty, polished stainless flaps; and mounting hardware was included. They were well packed, shipped fast and at a very reasonable amount. Best of all they were $26.00 cheaper a pair. So I saved $52.00, got fast delivery, and got a very nice product.....Thank you Autoplicity; definitely saved in my favorites....Bill in Pittsburgh, Pa.

Great price and fast shipping eBay can't even match
