Anode Bolt Size

[captainbob]

I'm having a senior moment. Need to change the trim anode on my F250 lower unit, but I can't remember the bolt size. Saw a thread about it on here before, but can't seem to find it either.

Probably 15mm, but if someone knows for sure, I would like to be prepared.

It's a 10mm bolt, takes a 12mm socket to remove.

Thanks very much!
