Propeller Polishing Sea Service

In an effort to achieve minimum fuel burn and 100% propeller efficiency with the assistance of a clean hull Sea Service Diving and Marine utilises modern techniques to achieve the propeller designer’s requirements for the surface finish of the propeller. The techniques employed have had proven results in reducing the fuel burn on both recreational and commercial vessels of all sizes. Sea Service will also make note of any chips and folds found on your propellers whilst conducting a thorough clean.
