To maintain the performance of a propeller, it is essential to keep both sides clean, the leading edge of the blades and especially the ends. The proliferation of anatives and algae has a significant impact on engine performance.


The anatives attach to the Zytel blades, with the same speed as on any other surface prone to the proliferation of dirt.

We do not recommend any antifouling in particular because we consider that the place of parking is a determining factor in the choice of the product to apply due to the specific environment at each location. Water temperature, light, current, water salinity, suspended particles and the type of use of the boat are all factors that have a significant impact on antifouling performance.


We recommend painting the entire propeller with modern self-erosion antifouling by applying it directly to the propeller. No application of a special underlay is required on the Zytel™ and Delrin™.

With a gradual erosion of the paint at the end of the blades, this solution remains overall the best to fight against the fouling of the propeller.


If you are not using relatively fast wear self-erosion antifouling on the surface of rotating blades, be careful to ensure that no accumulation of antifouling is gradually created in the contact area between the blade and the propeller hub.

The use of copper antifouling is strictly prohibited on all saildrive headers.


Always use the same antifouling on the propeller and on the saildrive base.

NB: Be sure to eliminate any dripping on the propeller especially near the leading edge at the risk, otherwise, of creating significant vibration problems.

PROPSPEED: Experience has shown that this type of antifouling is very effective on the composite parts of Kiwiprop™ propellers. It has no tendency to lose its adhesion qualities on the Zytel™ and has demonstrated its effectiveness over time.
