So.. this is my heat exchanger, i had the corrosion welded 5 years ago.
and now even that has corroded. I have read on the web that im not the
only person experiencing this problem.. Any one here had similar? how did
you fix it? I priced a new on from Yanmar - close to half the price of a new engine???

Interesting ..... Seems very expensive for a component ! ........... Why not cut it in half , and copy it .... Get it fabricated ??? Maybe even make it better ??
