The 11 3/8X12 A3R PROP by Polastorm Series is an aerospace casting technology breakthrough for marine aluminum propellers that is high-quality and extremely strong. This propeller fits YAMAHA 25-60HP with 13 spline tooth shafts, T25hp (after 2010), and F30/40/50/60HP applications. It is a combination deposition of strontium, aluminum, and titanium that is far stronger and stiffer than standard propellers, with a tensile strength of 280 MPA and a yield strength of 220 MPA, making it far more efficient than typical die-casting and squeeze casting props.
Key Features:
- These are robotic powder-coated with AkzoNobel patent-protected anti-corrosive coating powder.
- Props are developed with suitable cupping and camber predicated on OEM blade geometry.
- It has excellent bow lift, acceleration, and top speed, while also reducing slip and advancing bite.
- Prop fits YAMAHA 25-60HP with a 13-spline tooth shaft, T25hp (after 2010), and F30/40/50/60HP.
