Volvo 3-blade folding prop zinc

Hi, this hemispherical zinc at the end of the propeller is nowhere to be found in Volvo catalogs. They just have the 2-part circular ring around the shaft.

It has 3 bolts along the perimeter and one in the center. Does anyone know where I can get one?

That is not a Volvo propeller.

Re: Volvo 3-blade folding prop zinc

I don't think those three Allen head fasteners penetrate the zinc. You need to find out what kind of folding prop you have and then get something like this:

FX Flexofold Propeller Zinc Anode

Re: Volvo 3-blade folding prop zinc

FWIW,

I got tired of paying the exorbitant price for the Flex-O-Fold anodes and made a simple modification which allows the use of generic "donut" zincs in their place.

All it takes is countersinking the three screws that hold the plate onto the hub, and buying three countersunk head allen screws to replace the cap screws that come from the factory. Then by putting a flat washer on the central screw that holds the anode on and tightening it up, Bob's your uncle. This has worked for us for the past 6 years.

The donut zincs don't have quite as much mass as the factory ones, but on our boat they easily last between slippings. The price differential in Oz is two donuts for about 12 dollars vs around 50 for one factory job.

Cheers,

Jim
