I'm a new owner looking to buy zincs from Boat Zinc's. Can anyone help with a list of needed zincs for a 2014 31S (Volvo Penta R4-300)
 
Believe they are all called out in the spare order form list on the main page. Just ordered a bunch of spares, saw the zincs on there, but didn't need them yet.
 
I just replaced all of my zincs a month ago. Here is the complete list for the boat proper, plus the one for the Onan. Or maybe the Volvo. Can't remember which. Also, in my 2 am haste to order, I accidentally ordered two prop nut zincs. You only need one.

Anyway, when you plug in the part numbers FM gives you in to the Boatzincs website, some come back with multiple options. These are the correct part numbers and quantities (excepting the prop one), to order from Boatzincs. And yes, their nomenclature is weird and inconsistent. Also, pardon the formatting, this forum software is ****.

Propeller Nut F Zinc Anode (1-1/2") - Replacement PropNut-F-Zinc (qty 2) $20.35 (prop)

Propeller Nut C/D/E/F Mounting Screw PropNutScrew-CDEF (qty 1) $1.87 (prop zinc screw, figured it would be corroded bad but it was actually pretty good)

R-3 Rudder Zinc Anode - 3-3/4" Dia. R-3 (qty 2) $10.02 (trim tabs)

SM31180A Side-Power Aluminum Anode SM31180A (qty 2) $7.32 (thrusters)

Slotted ZHC-5 Zinc Anode (ZHC-5S) ZHC-5S (qty 1) $29.55 (stern plate)

Subtotal 112.95

Grand Total 158.59
 
Thanks. This will save me a bunch of trial and error!
