Propeller Polishing in Ross Dependency, Impeller Mercury 15 Hp - Marine Propulsion

Propeller polishing enhances the surface smoothness of marine propellers, reducing drag and improving efficiency. It helps maintain optimal performance and fuel economy in marine propulsion systems. Regular polishing also prevents corrosion and extends the propeller's lifespan.

Size: Typically ranges from 0.5 to 6 meters in diameter, depending on vessel type.

Grade: Marine-grade alloys (e.g., NiAl bronze, stainless steel, or manganese bronze).

Viscosity: N/A (propellers operate in water, not a fluid with viscosity specifications).

Buoyancy: Neutral or slightly negative buoyancy to maintain submersion.

Material: High-strength corrosion-resistant alloys (e.g., CuNiAl, 316L stainless steel, or composite materials).

Blade Count: 3 to 6 blades, optimized for efficiency and cavitation reduction.

Surface Finish: Polished to reduce drag and improve hydrodynamic performance.

Pitch: Adjustable or fixed, measured in degrees or inches/revolution.

RPM Range: 50–1,500 RPM, depending on propulsion system and vessel size.

Load Capacity: Designed to withstand thrust loads up to 50+ tons for large vessels.
