Propeller Polishing
In the ever-evolving realm of maritime transportation, the propeller stands as a linchpin for a vessel's efficiency, safety, and overall prowess. Exposed to the relentless elements of the marine environment, propellers undergo continuous stress, resulting in wear and tear that significantly impacts operational effectiveness and lifespan.
At SIFM, we have established ourselves as a leading provider of propeller maintenance and repair services, offering unmatched expertise, specialized tools, and a commitment to quality. We use professional-grade polishing machines — UMC International MK2 and MODEL MC111 — to restore propeller blades to their smooth design condition.
A polished propeller reduces skin friction drag on the blade surface, directly lowering fuel consumption and improving vessel speed. Regular polishing also reduces vibration and cavitation, extending propeller and bearing life.

Our Propeller Polishing Process
-
Initial Inspection
Underwater visual assessment of each blade — checking for fouling, surface roughness, pitting, and any damage requiring repair before polishing.
-
Coarse Surface Preparation
Removal of hard marine growth, barnacles, and heavy fouling from blade surfaces using hydraulic tools before the polishing stage begins.
-
Progressive Polishing
Our divers systematically polish each blade using professional-grade underwater polishing machines (UMC International MK2 / MC111) with progressively finer grits.
-
Final Surface Finish
Fine polishing pass to achieve a near-mirror smooth finish on blade surfaces, minimising skin friction and optimising hydrodynamic performance.
-
Performance Documentation
Post-polishing photographic report delivered with surface finish assessment for your vessel maintenance log.
