I asked the manager of one of the boat yards about using a shaft bush to protect the stuffing box. He basically said the box was "isolated" and didn't really need it. He went onto say that it is protected by the shaft zinc, that some boats use brushes when they don't have room for a external shaft zink. I told him, I have a external zink, but my stuffing box is turning pink (I'm a Poet and don't even know it!) He said, "well, like anything else, your stuffing box won't last forever". He didn't have any brushes on hand, so I went with my original idea (see next post) I'm probably missing something, but if the box is isolated, how is it protected by the external shaft zink? Wouldn't there be electrolysis generated between the Stainless shaft and the less noble stuffing box which also happens to leak salt water by design?
