Turning Point 15x15 RH Mach3 Stainless Steel Propeller

A 15-inch diameter and 15-inch pitch distinguish this Turning Point Express Mach3 EX-1415 propeller from the smaller EX1/EX2 models. It is a right-hand, three-blade stainless steel housing designed around Turning Point’s cupped Mach3 blade geometry. The relatively broad diameter makes gearcase and hull clearance checks important during replacement selection. It is intended for a properly matched engine and installation hub, not every 15-inch propeller application.

Turning Point uses TP17 stainless steel in its Express blades and provides generous exhaust-flow space through the hub. The cupped three-blade design aims to balance hole-shot response, cornering grip, and speed under suitable conditions. Fifteen inches of pitch may place a different load on the engine than a higher-pitch propeller even when the diameter is similar. Always use actual engine RPM and normal boat loading to evaluate a pitch change.

The EX-1415 propeller housing requires a separately selected Turning Point hub installation kit. Check the engine’s shaft, gearcase, and right-hand rotation requirements before choosing that kit. If changing from a four-blade design, expect performance characteristics to differ even at the same nominal pitch. Browse other stainless steel propellers through our marine department.
