Sierra Marine Propeller Cones

Not Yet Reviewed

Sierra Marine offers propeller cones for various OMC and Volvo Penta sterndrive applications. The propeller cones serve as a proprietary bushing that minimizes vibrations and stress on the drive components, while also preventing corrosion by galvanically protecting the stainless steel propeller from the aluminum drive casting. The high-quality criteria of the propeller cones ensure that your boat engine and drive system operate optimally.
