This stainless steel propeller from Polastorm belongs to the Sema series and is designed for Suzuki outboards. The propeller features three blades, a diameter of 14″, and a pitch of 17″.
The propeller is right-hand rotation (RH). The measurement 14 x 17 indicates the diameter and pitch in inches. The 17″ pitch corresponds to the theoretical forward movement of the propeller per revolution, while the actual movement depends on installation and operating conditions.
The construction is made of ASTM A890-4A duplex stainless steel and is solution heat-treated. The material specifications include a tensile strength of 680 MPa, a yield strength of 450 MPa, an elongation at break of 25%, and a hardness of 26 HRC.
The propeller uses a separate, interchangeable hub/shock absorber system. The hub kit is not included and must be selected based on the specific Suzuki engine model, year, gearcase, and propeller shaft. This product family is designed for the 40–140 hp class with a 4¼″ gearcase.
Choosing a hub kit
Hub kit F25, item no. 52.582.03, is used for Suzuki DF70A, DF80A, and DF90A 4-stroke from 2009. The hub kit is for a 4¼″/108 mm gearcase and 15-spline propeller shaft.
Hub kit F26, item no. 52.582.04, is used for Suzuki DF90 4-stroke from 2001–2008, DF100 4-stroke from 2009, and DF115 4-stroke from 2001–2012. The hub kit is for a 4¼″/108 mm gearcase and 15-spline propeller shaft.
Hub kit F27, item no. 52.582.05, is used for Suzuki DF115A and DF140A 4-stroke from 2013, as well as DF140 4-stroke from 2002–2012. The hub kit is for a 4¼″/108 mm gearcase and 15-spline propeller shaft.
The Sema propeller must not be used on Suzuki 2-stroke engines with a 13-spline propeller shaft or on OMC/Johnson engines covered by the Sema series 13-spline exception.
Always check the engine model, year, gearcase, propeller shaft, and required hub kit before purchasing.
