This Polastorm Stella 3-blade duplex stainless steel propeller for 4¾″ gearcase has a diameter of 14¼″, a pitch of 17″, and left-hand rotation. It is designed for outboards and compatible sterndrives, where the propeller is mounted using a separate, engine-specific hub kit.
The propeller is manufactured from ASTM A890-A4 duplex stainless steel using APC (Aerospace Precision Casting). The construction provides high material density and mechanical strength, while the steel's high chromium content contributes to corrosion resistance. The surface is high-gloss polished.
The interchangeable hub system allows the propeller to be adapted to the specific engine, shaft, and spline configuration. The hub kit is not included and must be ordered separately. The correct kit depends on the engine make, model, year, shaft diameter, and number of splines.
The propeller is designed for 4¾″ gearcases, equivalent to approximately 120.7 mm, and is recommended for engines in the 150–200 hp class. Hub-kit-dependent applications include selected engines and drives from Mercury, MerCruiser, Yamaha, Honda, Suzuki, Evinrude, Johnson, and Volvo Penta. Possible hub kits include item nos. 52.580.02, 52.580.03, 52.581.03, 52.582.06, 52.583.02, and 52.586.01; the choice must be made based on the specific engine setup.
The Stella model is equivalent in type to the Solas New Saturn and Solas Rubex NS3. The manufacturer's part number is 5886-3143-17. Cross-references include Michigan Apollo 993053 as well as the functional application references Mercury 48-16315A46, Mercury 8M0151404, and Quicksilver QS5053X. The Mercury references have a nominally stated diameter of 14½″ and should therefore not be considered identical in dimensions to this 14¼″ propeller.
The left-hand version is relevant, among other things, as a counterpart to a right-hand propeller in a correctly dimensioned installation with counter-rotating engines. The diameter, pitch, rotation direction, and choice of hub kit must always match the boat's engine and drive setup.
Always check the engine/drive model, gearcase, shaft, splines, rotation direction, and original part number before purchasing.
