Osculati 43.100.00 – Renault Marine Propeller Shaft Nut Zinc Anode 22/25 mm

The Osculati 43.100.00 is a compact, high-purity zinc anode designed to thread directly onto propeller shaft nuts used in Renault Marine systems with shaft diameters of 22–25 mm. Featuring a 16×2 mm thread, it provides concentrated galvanic protection where corrosion commonly initiates: the shaft-end nut. Its dimensions (35 mm height, 27 mm diameter) ensure easy fitment and minimal disruption to water flow, making it a vital component for extending the service life of shaft threads and nearby hardware in saltwater environments.
