This listing is for the complete PolaStorm Blade Unit + PolaFlex Hub Kit assembly - everything required to fit to your engine (except tools and grease!).
This high quality 3-blade "Saltist Series" polished stainless propeller blade unit from PolaStorm is designed with high-rake blade geometry for aggressive acceleration & excellent bow lift, and utilizes a spiral flute exhaust design making it ideal for deep vee craft with high horsepower engines. ASTM A890-4A duplex stainless steel formulation is used for the casting, followed by heat treatment to create tensile strength of up to 750 Mpa and extreme anti-corrosion.
PolaFlex high quality propeller bushes are constructed from rubber (not plastic) to aid softer shifting into gear, reduce vibration and improve impact deflection. They have tough brass bronze splines, not aluminium as found with lesser brands.
