Turning Point Express Mach3 EX1/EX2-1321 Propeller, 13.25 x 21, 3-Blade, RH – 31432112

The Turning Point Express® Mach3™ EX1/EX2-1321 is a three-blade stainless steel propeller with a 13.25-inch diameter, 21-inch pitch, and right-hand rotation. Designed with aggressive pitch angles and sharp cup profiles, the Mach3 series focuses on top-end speed, acceleration, and handling.

For boaters considering an upgrade from aluminum or an older propeller design, this model combines Turning Point's performance-oriented blade geometry with proprietary TP17™ stainless steel. Select the correct propeller and hub kit for your engine and boating needs; performance depends on the boat, engine, load, and setup.
