Hustler Propeller 14.5x17 – 4-Blade Aluminum, RH Rotation | 90–300+hp (4.75" Gearcase)

Hustler Aluminum Propeller — 14.5 x 17, 4-Blade, Right-Hand Rotation

The Hustler 4-blade is a high-performance aluminum propeller built on a Dual Geometry platform — delivering the hole shot, handling, and load-carrying advantages of a 4-blade design without the top-end speed penalty that typically comes with it. Engineered for high-horsepower outboards and sterndrives from 90 to 300+hp with 4.75-inch gearcases, and manufactured using a proprietary squeeze-casting process that delivers near-stainless-steel performance at an aluminum price.

Best Use Case

The 4-blade Hustler in 14.5 x 17 pitch is ideal for watersports boats, sterndrive applications, tri-toons, and bay boats running 90–300+hp outboards or sterndrives where acceleration, cornering, and load-carrying matter as much as top-end speed. The 17-pitch delivers a strong balance of hole shot and top-end performance — well-suited to boats that carry variable loads, tow riders, or need confident handling in choppy conditions. It’s an excellent upgrade over older OEM aluminum designs and will outperform most 5-blade ski props in real-world conditions.

Dual Geometry — How It Works

Two blades use an aggressive variable-rake design for explosive acceleration and cornering grip. The other two use an offshore-style profile for high-speed efficiency and maximum stern lift. The result: 4-blade handling and load capacity with 3-blade top-end speed — and full hull lift that maintains speed under load where a 3-blade can lose up to 3 mph.

Key Features

• Squeeze-Cast Aluminum Construction — A proprietary casting process creates a denser, tighter grain structure than standard die-cast aluminum, resulting in stiffer blades that flex less under load and transfer more power to the water.
• Stainless Steel Blade Geometry — Built from the same blade geometry as the Express stainless steel line, delivering performance within 0.5–1 mph of its stainless counterpart.
• 4-Blade Dual Geometry Design — Two blade geometries in one hub: aggressive rake for hole shot and handling, offshore profile for speed and stern lift.
• Full Hull Lift — Raises the entire hull higher out of the water, reducing wetted surface and maintaining top speed under heavy loads.
• Tuned Exhaust Vents — Reduce water density around the blades during acceleration for faster hole shots and improved horsepower delivery.
• Ultracoat™ 5-Step Powder-Coat Finish — A durable, automotive-grade powder coat protects against corrosion and abrasion.
• Broad Engine Compatibility — Fits COX, Evinrude, Honda, Johnson, Mariner, Mercury, MerCruiser, Nissan, OMC, OXE, Parsun, Suzuki, Tohatsu, Volvo Penta, and Yamaha outboards and sterndrives.

The 17-pitch is a mid-range option in this gearcase family. Step up to a 19-pitch for more top-end speed on lighter hulls, or step down to a 15-pitch for stronger hole shot under heavier loads.
