This Polastorm SEMA aluminum propeller for Suzuki outboard motors is a 3-blade propeller with a 14″ diameter, 19″ pitch, and 15-spline shaft connection. It is designed for select Suzuki 4-stroke engines with a 4¼″ gearcase.
The propeller is made of aluminum and is part of the SEMA series with Suzuki geometry. Polastorm’s aluminum propellers are manufactured using APC precision casting and a heat-treated hybrid alloy based on A356 with strontium, magnesium, and titanium. The anti-corrosion powder coating is applied via robotics.
The dimensions 14 x 19″ indicate a 14″ propeller diameter and a 19″ pitch. The pitch describes the propeller's theoretical forward movement per revolution, while actual performance depends on factors such as boat type, load, gear ratio, and the engine's full-throttle RPM range. Engine compatibility therefore does not necessarily mean that a 19″ pitch is the optimal dimension for every installation.
Compatible engine models
Fits Suzuki DF50/60AX from 2014, DF70A from 2009, DF90 from 2001-2008, DF90A/100 from 2009, DF115/115A from 2001, DF115SS from 2020, and DF140/140A from 2002. Compatibility applies to Suzuki 4-stroke engines with a 4¼″ gearcase and 15-spline propeller shaft.
OEM cross-references
The propeller cross-references to Suzuki OEM no. 58100-90J11-019. Number 58100-90JB0-019 is documented as the successor, while 990C0-00760-19P is a supplementary Suzuki cross-reference. This product is a Polastorm replacement propeller and not an original Suzuki part.
Always check engine model, year, gearcase, number of splines, original part number, and the engine's recommended full-throttle RPM range before purchase.
