Westerbeke Generator neglect

[Dalton]

Haven’t used my generator yet and I’ve been focusing on fixing other things on this new (to me ) boat. Wanted to flush generator with only 60 hours on it and noticed it wasn’t sucking in any raw water. Took out the impeller and replaced it with a new one (old one was fine) and then removed the heat exchanger and find this….see picture.  Well, no wonder!

I guess it proves how important it is to not let sea water just sit & destroy.

So my question is should I use something like barnicle buster or just clean by hand and use a 1/8″ rod for the tubes? I bought new end caps, gaskets, etc

Bath & Shower

Yup, that mix will do it… a half hour bath in that and then a good fresh water rinsing.  Keep the pics coming, thanks.

10% muriatic acid   90% water would be sufficient?

I use muriatic acid for my pool but don’t know the ratio or if its pure.

Soak it!

Ken, that thing needs to soak in some 10:1 muriatic acid and have a nice long bath… better assess your entire seawater-side cooling circuit to ensure passages, etc. are ALL clean and ready to cool efficiently!

Wow, that thing has been living on cheeseburgers and french fries!  Yes manually clean it out first and carefully rod out the tubes and then use a descaler – vinegar, Rydlyme, diluted acid – there are choices…
