Turning Point Express Mach3 Stainless Propeller, 13.75 x 15, RH, 3-Blade

Three-blade stainless steel performance

The Turning Point Express Mach3 EX1/EX2-1315 combines a 13.75-inch diameter, 15 pitch and right-hand rotation. Aggressive pitch angles and sharp cup profiles are designed to support top speed, acceleration, hole shot and cornering. Actual performance and fuel economy depend on your boat, engine, load and setup.

Verify fit and select the required hub kit

A hub kit is required for installation. Use the Turning Point Selection Chart or Prop Wizard to verify this propeller's fit and select the correct hub kit for your exact engine and drive before ordering.

The broader Express family covers 9.9 hp Bigfoot through 300+ hp outboard and sterndrive applications from Evinrude, Force, Honda, Johnson, Mariner, Mercruiser, Mercury, Nissan, OMC, Parsun, Suzuki, Tohatsu, Volvo Penta and Yamaha. This is family-level guidance, not confirmation that this particular model fits every engine in that range. The advertised lifetime warranty applies to MasterGuard installation kits, not to this propeller.

Material and exhaust design

• TP17 stainless steel: Turning Point's proprietary material developed for Express Mach3 and Mach4 designs, with a focus on strength, durability and corrosion resistance.
• Advertised material comparisons: Turning Point describes 20% higher chromium content, almost 250% stronger material and five times greater durability versus competing or conventional stainless steel. The supplied copy does not identify the comparison materials or test conditions.
• Large exhaust pathways: Designed to promote exhaust flow and reduce backpressure. Advertised exhaust-flow area is 40% greater than competing products; the supplied copy does not identify the comparison product.

Turning Point positions Mach3 as an upgrade from aluminum or older-generation propeller designs. Any performance gains, fuel savings or claimed one-to-two-season payback depend on your particular setup and use, rather than being guaranteed.
