Corrosion in Heat Exchanger & Exhaust Elbow

Hello Cruisers,

in our Broadblue 42, we have two Volvo Penta D2-55. After we found major corrosion on the port side exhaust elbow and heat exchanger which ultimately needed replacement, we asked the engineers to take it on the starboar side apart as well to doublecheck there (we are not on the boat atm).

Results see pictures attached, what would you recommend us? Engineer is recommending to exchange, but they always recommend to exchange everything. And whilst it would be okay to exchange the exhaust elbow, the heat exchanger would be a high-ticket item we would not want to spend this season...

So would it be valid to ask the mechanics to just clean and repair the heat exchanger? What is with the exhaust elbow?

Greetings
Timo

Re: Corrosion in Heat Exchanger & Exhaust Elbow

the whole is very sick... you will have to think about replacing (aïe...)
be careful to fit good seals when reassembling ...
