Polastorm Polaflex propeller hub kit F42 is an interchangeable hub, damper, and mounting kit for compatible hubless Polastorm propellers. This variant is designed for the Volvo SX Sterndrive with a 19-spline propeller shaft and a 4 3/4" (120.7 mm) gearcase.
The F42 functions as an interface between the propeller and the propeller shaft. The Polaflex system utilizes a brass metal hub with a rubber bushing, which provides the cushioning connection in the interchangeable hub system. The kit belongs to Polastorm's compatibility group E.
The kit consists of a hub/damper element, thrust washer, front washer, spacer, and nut. The documented component numbers for the F42 are 86511 for the thrust washer, 80907 for the hub bushing, 86523 for the rear spacer, and 82551 for the final mounting part.
The primary application is the Volvo SX Sterndrive from 1994 and newer. The F42 is also compatible with the OMC/Cobra SX from 1994 and newer, provided the drive has a 19-spline propeller shaft and a 4 3/4" gearcase. The kit is not a complete propeller, but the necessary hub and mounting kit for a compatible propeller without an integrated hub.
The external product number 124-88-F42 is used as a reference for this F42 kit. Always verify the drive model, gearcase size, number of splines, and propeller compatibility before purchase.
