Heat Exchanger Anode

[SV Hope]

Hello and greetings from "down under''

I have discovered that my Seakamp Heat Exchanger (HE) is missing its zinc anode. Where the anode is supposed to be screwed in, the previous owner has connected a short hose which runs from the HE to the PSS shaft seal. Is this an acceptable way to provide lubrication to the shaft? (at the expense of the HE) If I should change this, is there a preferred way to set it up?

Thanks in advance
Michael

Hi
I don't see a big problem other than the suplie to the shaft seal is normally at sea level pressure the H/E is at pump pressure,if the exhaust outlet gets a bit blocked it could force the seal apart ( i think ) also i don't think i would be happy to run to long with out a anode,but after saying that mine is still good after 2 years use

Are we talking about the heat exchanger that is above the tranny....(guess)...3.5"x 10" cylinder....and the anode screws in the starboard bottom.

The heat exchanger actually measures 3"x14.5". It sits above the flywheel housing, and the anode screws into an opening on the right hand side of the unit when viewing the set up from the companionway. There is another hose in the starboard bottom which appears to be taking the cooling seawater (?) to the exhaust elbow. (If I have got that figured correctly) Thanks.
