Turning Point 14.5x17 LH Mach4 Stainless Steel Propeller

This Turning Point Express Mach4 is the left-hand EX-1417-4L version, with a 14.5-inch diameter and 17-inch pitch. Its four blades use TP17 stainless steel and a cupped profile intended to hold the water during acceleration and turns. The left-hand rotation is a defining fitment detail, particularly when choosing a propeller for a counter-rotating drive. It is not interchangeable with a right-hand propeller of the same size.

Turning Point’s Mach4 geometry emphasizes control and hole-shot response without ignoring cruising performance. The 17-inch pitch provides a different engine load than the 21-inch left-hand model in this batch. Its hub housing incorporates the Express series’ large exhaust-flow passages. Whether this pitch is correct depends on the boat’s real operating RPM with the typical load aboard.

Confirm the drive rotation first, then review the propeller’s diameter and pitch against the engine manufacturer’s operating range. This stainless housing requires a separate, engine-matched installation hub. Verify which kit fits the particular shaft before assembly instead of assuming every Express propeller shares one hub.
