Product Overview

If you are looking for improved hole shot and the ability to plane at lower speeds, consider a Turning Point Express® Mach4™ Stainless Steel Four-Blade prop. 

Turning Point Express® Mach4™ Stainless Steel Propellers combine premium materials with a highly evolved production process.

Turning Point has taken the proven techniques that led to Hustler®, the world's best-performing aluminum propellers, and applied them to their stainless steel propellers. Combining stronger materials, more corrosion resistance, higher gloss, and new casting technology with cutting-edge designs, Turning Point gives you the new Express® Mach4™ Propellers.

Turning Point has completely re-designed the stainless propeller production process to bring state-of-the-art casting technologies and race-proven finish and tuning practices to their new line of Express props. Turning Point’s SpeedShop™ Blueprinting and MaxSpeed™ Dyno Balance Processes, a $500 option with other manufacturers, are standard on every prop.

Turning Point's new proprietary stainless steel, TP17™, has over 20 percent more Chromium than the competition for improved finish and corrosion resistance. This allows Turning Point’s engineers and designers the freedom to produce radical new designs that will help you wring the best performance out of your boat.
