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.

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.
