Re: 3YM20 sacrificial zincs
Welcome aboard CF Amaleo, sorry I can't help you directly but on the Yanmar GM series, there is one zinc in the block sort of underneath the exhaust manifold and another at the back of the head (gearbox side). They are steel plugs with a 24mm hex head. Remove the plugs and the zinc is screwed into the inside of the plug.
The 3YM might be similar.
Hope this helps.
