This Polastorm Sema aluminum propeller for Suzuki 8–20 hp is a 3-blade outboard propeller with a diameter of 9 1/4″, a pitch of 11″, and 10 splines. It is intended as an alternative propeller for selected Suzuki outboard engines with a 2 1/2″ gearcase.
The propeller is manufactured from aluminum and features Sema geometry, which corresponds to the geometry of Suzuki’s original propellers. It has standard right-hand rotation and an integrated fixed hub, so the construction does not require a separate replaceable hub kit. The propeller's diameter is equivalent to 235.0 mm, while the pitch is equivalent to 279.4 mm.
The overall engine compatibility includes Suzuki 4-stroke engines of 8, 9.9, 15, and 20 hp as well as 2-stroke engines of 9.9, 15, and 20 hp. Compatibility requires a 10-spline propeller shaft and a 2 1/2″ gearcase.
Compatible engine models
Compatible engine families include DF8A, DF9.9, DF9.9A, DF9.9B, DF15, DF15A, DF20A, DT9.9, DT9.9A, DT15, and DT15A. Documented model years include DF8A from 2011, DF9.9 from 1996, DF9.9A/B from 2010, DF15 from 1996 to 2012, DF15A/DF20A from 2013, DT9.9 from 1983 to 1987, and DT15 from 1983 to 1988.
OEM and cross-references
The propeller corresponds to Suzuki OEM no. 58100-89L70-019 and Suzuki propeller code M1101. The former OEM no. 58100-93743-019 has been replaced by 58100-89L70-019. The Polastorm cross-reference is 1237-3093-11.
Always check the engine/drive model, gearcase size, number of splines, and original part number before purchasing. Engine hp alone is not sufficient to determine compatibility.
