Quality is of paramount importance to us and our propeller manufacturers. Situated in various locations around the world, adjacent to major ship building centres, they have been carefully selected to ensure their finished products meet the exceptionally high standards that both we, and our clients expect.

Strict quality control is exercised at every stage of propeller production – embracing design through to complete manufacture – not only to meet our stringent internal standards but also those of customers, classification societies and recognised international bodies. SMP is accredited to ISO9001:2008 and our selected manufacturing plants have equivalent accreditation.

Stone Marine Propulsion’s production partners manufacture propellers from the smallest to the very largest, and in a range of propeller materials to suit every application.
