Polastorm Star 3-blade stainless steel propeller for 25–70 hp is a propeller for outboard motors with a diameter of 11 3/8" and a pitch of 14". The Star profile is recommended for Suzuki, Yamaha, and Selva within the documented engine group when the propeller is combined with the correct engine-specific hub kit.
The propeller has three blades and is manufactured from ASTM A890-4A duplex stainless steel. The material is heat-treated and has a high chromium content, which contributes to high strength and corrosion resistance in maritime environments. Manufacturing is performed via Aerospace Precision Casting, which provides high material density and a precise construction.
The size 11 3/8 x 14 indicates diameter x pitch. The diameter is 11 3/8" (approx. 288.9 mm), while the pitch is 14" (355.6 mm). The propeller belongs to the 3 1/4" gearcase class and has a profile that is equivalent to Solas New Saturn and Solas Rubex NS3.
The propeller is supplied without a hub and shock absorber. A suitable Polastorm hub kit must therefore be ordered separately based on engine make, gearcase diameter, and propeller shaft splines. The engine-specific hub kit completes the installation with a shock absorber, thrust washer, front washer, spacer, and nut.
Compatibility with a specific engine cannot be determined solely based on the power range. Always check the engine's gearcase, propeller shaft, splines, and hub kit requirements before ordering.
