This Polastorm Saltist stainless steel propeller for Volvo Penta SX/OMC Cobra SX is a 3-blade, right-hand rotation sterndrive propeller with a diameter of 14 3/4" and a pitch of 19". The variant is designed for single-propeller drives and has a hub profile with 19 splines.
The propeller's diameter corresponds to approx. 374.65 mm, while the geometric pitch corresponds to approx. 482.6 mm. The combination 14 3/4 x 19 describes the diameter and pitch in inches. The correct pitch must be chosen based on the engine's recommended full-throttle RPM, the drive's gear ratio, the boat's weight, and the existing propeller.
The Saltist propeller is manufactured from ASTM A890-4A duplex stainless steel and is solution heat-treated. It is produced using APC precision casting, which provides high material density and physical strength. The material's specified properties include a tensile strength of 680 MPa, yield strength of 450 MPa, elongation at break of 25%, and a hardness of 26 HRC.
The alloy's chromium and copper content contribute to corrosion resistance and acid resistance, respectively. The propeller design features helical through-hub exhaust, so the engine exhaust is routed through the propeller hub.
The propeller is compatible with Volvo Penta SX sterndrives from 1994 and OMC Cobra SX with a 19-tooth propeller shaft. It is right-hand rotating and must not be confused with a left-hand rotating variant or a propeller for Volvo Penta Duoprop drives.
Always check the drive model, number of splines, rotation direction, diameter, and pitch before purchase.
