For the 4 blade folding propeller there are 2 types of propellers available, however the differences are based on diameter as there is no sail drive option for the 4 blade propeller. For the 4 blade propeller less than 26″ in diameter (VF-120) most of the spare parts fitted to the 3 blade propeller are used, this includes the zinc anode (VF3AN), pivot pins, pads and fasteners. However once the diameter is increased to over 26″ the zinc anode, pads and parts all become substantially larger to allow for the larger diameter and hence loading. To see how easy it is to fit a large propeller zinc anode to the 4 blade propeller VF4AN zinc anode page. The most common spare parts (with links to the store) for the 4 blade Varifold folding propeller on our online store are Left – Varifold 4 blade anode, Center – Varifold 4 blade buffer pad (old style) and Right – Varifold 4 blade buffer pad (new style).
