Engine anode missing on a Volvo Penta 2002?

[anastas]

Hi all,

I have a Beneteau First 31 ('92) with a Volvo Penta 2002-variant and recently wanted to
replace the engine anode.
Looking at the schematics, it seems that the anode is placed in the whole that
is also used for supplying hot coolant to a water heater (if installed).
In my boat indeed a water heater is installed, so my question is, do I not have an engine anode?

In addition, I would think that the engine anode is on the "raw/sea water" side of the cooling system, not in the coolant side.
I do not see any such anode on the heat exchanger.

Any thoughts?

thanks

do I not have an engine anode?

No

My VP22MD has none or spot for one.

Why?

Your engine should be Galvanically Coupled to your shaft which should have Zincs on your shaft.
Shaft Zincs protect the engine and Water heater also.

The 2000 series Volvos only use an anode if raw water cooled..
