A 3-blade aluminum propeller from Polastorm in the SOLTIGA 3 series, sized 15 1/2 x 17 LH. The propeller is left-hand rotating and intended for Volvo SX Sterndrive and Cobra SX OMC.
The propeller has a diameter of 15 1/2″ and a pitch of 17″. The left-hand rotation is indicated by LH, while the connection to the propeller shaft has 19 splines. The combination of size, rotation, and shaft connection must match the specific drive.
The material is an A356-based aluminum alloy with strontium, magnesium, and titanium. The propeller is manufactured using APC precision casting with controlled casting pressure and post-processed with solution heat treatment and artificial aging.
The aluminum alloy has a declared tensile strength of 280 MPa, a yield strength of 220 MPa, and a hardness of 89 HB. The surface features a robotically applied anti-corrosive powder coating, which protects the aluminum in the marine environment.
The propeller is specifically configured for left-hand installation on Volvo SX Sterndrive and Cobra SX OMC with a 19-spline propeller shaft. Always check the drive type, rotation direction, diameter, pitch, and number of splines before purchasing.
