Galvanic Bonding
Been trying to trace the bonding system on my 1980 vintage Pearson, as I noticed a couple of through-hulls are not connected.

The existing bonding seems to come together in the stern on one propeller strut bolt; this bolt has two wires/cables, one linked to the bonding circuit, the other disconnected.

It looks like the boat ground is connected to the an engine bolt right next to the disconnected cable and the bonding my question is, should
the bonding system be grounded to the common ground, connecting to the same engine bolt as the battery ground, and thereby to the sacrificial anodes?

I am worrying because as I was changing the zincs, the propeller strut
was looking a bit pitted; could have been my imagination (the
visibility was about 4 inches!!), but.....

On my vintage P30 the bonding wires are brought to the same bolt on the engine block as the battery ground.
