DIY Engine anodes?

The anodes in my 2GM Yanmar need to be replaced. I have some propshaft anodes lying around that I will never use, and was wondering why I couldn't cut off a piece of the right size and shape, tap it and thread it onto the carrier that screws into the engine.

Can anyone tell me why I can't do this?

cheers, lockie

That will of course work perfectly fine.

Re: DIY Engine anodes?

If you go here>> Yanmar Engine Zinc Anodes you can just buy what you want.

But shipping overseas is expensive.

Yes thanks for that but you're right, shipping a lump of zinc all the way to Oz will be a tad pricey.

I could go and pay thru the nose at the local Yanmar dealer, but I hate getting ripped off. Conversely I love to subvert them by finding generic equivalents for stuff like bearings, seals, filters etc. It's all down to my youthful "me vs the military-industrial complex" complex.

cheers, lockie

Re: DIY Engine anodes?

I have been making my own the same way you detail for years. The latest model uses a tube fitting and I just loosen off the nut and bump a little more rod through the nylon olive and re-tighten.

Well I share your general philosophy but in this instance I'm not sure whether it's worth the effort.

The local Yanmar price is $13.20 each and I see that after market ones are available on-line in Oz for $9.00 each.

But don't get me started on Yanmar air filters… watch this space...
