LM32 Anodes

[chinita]

A friend has recently bought an LM32.

Seems to have an anode on the saildrive but none on the hull. No evidence of any bolts for previous anodes either.

Should there be a hull anode and, if so, what is it protecting?

TIA

I have an LM30 and it has never had hull anodes. The sail drive anode lasts a couple of seasons. The engine pencil anode gets changed at least once each year.

No reason why it should have a hull anode. The saildrive has its own anode to protect the casing and there may be an anode on the prop if it is a folding or feathering prop. The standard prop is aluminium with a rubber bush to isolate it from the drive.

Thanks everybody. I actually have an LM26 with no hull anode but I thought I would check before I advised him!
