Turning Point Propellers Express Mach3 Stainless Steel Propeller 31431712, 13.25x17 3-Blade RH for Evinrude Outboards

The Turning Point Propellers 31431712 is a stainless steel outboard propeller from the Express Mach3 series, sized 13.25 x 17 with a 3-blade right-hand rotation design built for Evinrude outboard applications. It is machined from 15-5 stainless steel, a grade that gets harder and stronger with age, giving the blades long-term durability against the stresses of high-performance running. The propeller uses higher rake angles to tighten the vortex the blades produce, which adds boat lift and improves overall performance, while aggressive cupping further sharpens handling and lift at speed. Tuned progressive pitch angles across the blade face accelerate water flow and channel it more efficiently, reducing slip so the engine converts more of its power into forward thrust and fuel economy. Tuned vents are built into the blade design to promote a fast hole shot, helping the boat get up on plane quickly from a standing start. This propeller is intended as a direct fit for Evinrude outboard motors and is supplied as a single propeller unit. Buyers running Evinrude outboards looking for a stainless steel upgrade with performance-oriented rake, cupping, and venting will find the 31431712 built specifically for aggressive handling and hole-shot performance rather than general cruising use.

Frequently Asked Questions

What size is the Turning Point Propellers 31431712? The 31431712 is a 13.25 x 17 size propeller, meaning a 13.25 inch diameter with a 17 inch pitch.

How many blades does this propeller have and which way does it rotate? This propeller has 3 blades and is configured for right hand (RH) rotation, matching standard Evinrude outboard drive rotation.

What is the 31431712 propeller made of? It is made from 15-5 stainless steel, a stainless alloy that gets harder and stronger with age, giving the blades added durability under repeated high-load use.

What outboard motors does the 31431712 propeller fit? The Turning Point Propellers 31431712 is built for Evinrude outboard motors.

How much does the 31431712 propeller weigh? The propeller weighs 11 pounds.

Will this propeller improve hole shot and acceleration? Yes, the 31431712 uses tuned vents specifically designed to produce a fast hole shot, along with progressive pitch angles that accelerate and channel water to minimize slip.

Does the 31431712 come as a single propeller or a set? It ships as a single propeller unit.

How does the cupping on this propeller affect performance? The 31431712 uses aggressive rake and cupping to improve handling and increase boat lift compared to a flat-blade design.

What are the overall dimensions of the 31431712 as packaged? The item measures approximately 15 x 15 x 8 inches.

Is stainless steel a durable choice for a boat propeller like the 31431712? Yes, the 15-5 stainless steel used in the 31431712 resists corrosion and actually gets harder and stronger with age, making it a durable option for regular marine use.

Does higher rake angle on the 31431712 change how the boat handles? Yes, the higher rake angle tightens the vortex produced by the propeller, which adds boat lift and improves overall handling and performance.
