…that’s a very interesting post and so far I’ve had conflicting advice. A couple of weeks ago I bought all the winterising bits for the 2020D in my B32 Another Fantasy (filters, impeller, etc etc) and also asked for a saildrive anode. My local dealer told me that the zinc variety had been discontinued and replaced by an aluminium version; when I expressed surprise they said ‘it’s fine, no problem’ but wouldn’t be drawn when I asked how an aluminium anode gave protection to an aluminium saildrive casing. I chose not to buy it before seeking more ‘expert’ advice but there seems to be no clear answer, some say ‘ok’, others say ‘not a good idea, stick with zinc’. I’ll be interested to see if there are any opinions offered here!!
