Yanmar Saildrive SD20

[wizard]

Went to the boat today to change the anode on the saildrive only to find that the nut is bigger than the biggest spanner(24mmm) supplied in the Yanmar toolkit. Has anyone got the exact size of this beast so I can purchase the correct socket or spanner. Many thanks in advance.

32 / 33 mm i think but will be able to check tuesday and get back to you- its deffo one of them... Took ours out last weekend, still looks as new, so diped it into some acid to clean off the carbonate crap, and saved me self £5 /forums/images/graemlins/smile.gif

Thanks for the prompt reply. Sounds as though I wil have to muscle up for this one then !! By the way what acid do you use to clear the zinc - I like the sound of saving money.
