MULTI-D STAINLESS STEEL PROPELLER.NEW SATURN 13X21 RIGHT

Function and technical context

The Multi-d Inox.new Saturn 13×21 propeller is the fundamental propulsion element that transforms the mechanical energy of the engine into forward movement of the boat. Mounted directly on the transmission shaft, it works in the submerged propulsion system, where it constantly interacts with the water through its high-resistance stainless steel blades. Its correct operation determines displacement efficiency, acceleration capacity and fuel consumption; Progressive wear or impact against submerged objects reduces traction, generates vibrations in the hull and can cause cavitation that damages both the propeller and the shaft bearings.

When to replace this part?

Stainless steel propellers show visible wear when you see chipped, eroded blades or loss of material on the leading edges; They may also present cracks after impacts against rocks, corals or submerged remains. It is recommended that the condition of the propeller be inspected at least every sailing season and after any grounding or collision, as even minor damage substantially reduces performance and increases engine vibration. Replacing the propeller preventively when the first signs of deterioration are seen avoids major problems in the transmission system and guarantees safe navigation without abnormal vibrations.
