How does blade material grade affect cavitation resistance?

Cast bronze and stainless steel grades behave differently under high load. Check the row for the specific alloy designation, such as CuAl10Fe5Ni5 or 316L. Higher nickel content generally improves erosion resistance but increases cost. Match the alloy to your operating water salinity and speed.

What pitch tolerance is standard for fixed pitch props?

Tolerance is usually listed in degrees or millimeters per blade. Tighter tolerances require more machining time and higher precision casting. If your vessel has a narrow RPM window, you need tighter pitch control. Verify the tolerance value in the product description before ordering.

Does the Rotor Magnet listing impact propeller specs?

No, the Rotor Magnet listing is unrelated to Marine Propellers. It belongs to a different industrial category. Focus only on rows explicitly describing propeller blades, hubs, or shafts. Ignore unrelated items to avoid confusing your procurement data.

How do I verify the hub bore size?

The hub bore must match your vessel's shaft diameter exactly. Rows often list the bore diameter in millimeters. If the listing lacks this number, ask the seller directly. A custom bore incurs extra machining charges and longer lead times.

What inspection is needed for cast defects?

Visual inspection and dye penetrant testing are common for cast propellers. Forged props may require ultrasonic testing of the hub. Request the inspection report from the factory before payment. Do not rely on the seller's word alone for structural integrity.

How does packaging differ for large props?

Large Marine Propellers require wooden crates or steel frames to prevent damage. The row should specify if the item is crated or wrapped in plastic. Improper packaging leads to corrosion or bending during sea freight. Confirm packaging details to avoid hidden demurrage fees.
