This Polastorm Stella 3-blade stainless steel propeller has a 13 1/2″ diameter, 15″ pitch, and right-hand rotation. The propeller is designed for 40–140 hp outboard motors with a 4 1/4″ gearcase and is used with a separate, engine-specific hub kit.
The propeller is manufactured from ASTM A890-4A duplex stainless steel. The high chromium content contributes to corrosion resistance, while APC precision casting provides high material density and physical strength. The surface is polished, and the 3-blade Stella geometry is intended as a versatile solution with a focus on acceleration and efficient mid-range operation.
The interchangeable hub system allows the propeller to be adapted to different engine makes and propeller shafts. The hub and shock-absorbing hub insert are not included and must be selected separately based on engine, year, gearcase diameter, and number of splines. The Stella propeller comes with a spacer to be placed in front of the propeller. The spacer is not used for installation on OMC/Johnson and 2-stroke Suzuki engines with a 13-spline propeller shaft.
The propeller is recommended for Yamaha, Selva, Mercury, Honda, and Tohatsu with a suitable 4 1/4″ gearcase and correct hub kit. It is comparable in size and application to the Solas New Saturn and Solas Rubex NS 3, but the hub, installation parts, and materials must be checked separately.
The manufacturer part number is 4889-3135-15. Documented cross-references include Solas 9431-135-15, Michigan 993143, Mercury 48-16986A46 and 48-8M0151401, Quicksilver QS5116X, Suzuki 99105-00100, Turning Point 31431512, Yamaha 688-45978-60-00, and EMP P9431-1350-15.

Depending on the engine and propeller shaft, F22 (52.581.02), F24 (52.582.02), F25 (52.582.03), F26 (52.582.04), F27 (52.582.05), F31 (52.584.02), or F30 (52.585.02) can be used. The correct kit must be selected based on engine make, model, year, gearcase, and number of splines.
Always check the engine/drive model, gearcase diameter, propeller shaft spline count, and original part number before purchasing.
