10.2" x 11" 4-blade PolaStorm Aluminium Propeller Yamaha Selva 20-30hp, 10 tooth spline


PolaStorm produce incredibly strong, titanium-aluminium alloy propellers that equal or exceed OEM equivalents. We’re able to offer these at competitive prices, due to a shortened supply chain.

This 4 blade propeller is intended to help smaller boats get on the plane.  4 blade propellers generally offer greater thrust and stern lift. This propeller also has good rake, offering bow lift advantages when operating at speed. It should be considered a potential replacement to 3 blade aluminium propellers with higher than 11" pitch.

Why choose a PolaStorm QPIM propeller?

An advanced Aerospace Precision Casting (APC) process using Titanium/Strontium/Aluminium alloy, results in a product which is up to 33% stronger than traditional Die and Squeeze Cast aluminium propellers. They are then finished using a robotically applied AkzoNobel* patented, environmentally friendly, anti-corrosion powder coating.
