A Flexofold Propeller does not require big maintenance.
The Pivot pins and gears are water lubricated but adding waterproof grease to the moving parts will help the folding and unfolding.
The anode's primary function is to protect your Flexofold propeller from corrosion. While it's challenging to specify an exact replacement interval, an anode's lifespan can range from a single season to several years. However, it's important to inspect your anode annually for signs of wear and to gauge its remaining size. If it's reduced to about 50% of its original size, it's time to replace it. Typically, an anode can last between 1 to 3 years, depending on usage, water conditions, and the total number of anodes installed
