Quality Engine Zincs?

[WanderingStar]

I've read articles recommending caution in choosing zincs. But I can't locate the references. Which ones are best? I know some decay quickly, I changed the shaft zinc in may, it was oatmeal in july. Now I want to replace my engine zinc, and I want the best. Experiences?

If the zinc is depleting quickly, it may have nothing to do with the quality of the zinc. It could have to do with dodgy electrics. And if you're plugging into shore power it may not necessarily be your electrics.
Just a thought . . . . .

No shore power, few electrics. Tom Neale mentioned a brand in an article, but I don't remember.
