[C320-list] Perkins heat exchanger

[Steve Weinstein]

 When I had the problem with the C270 M20, Perkins did a worldwide search for me and found nothing.  But that was at the height of Covid and their foundry in Europe was shut down.  Don't know if it ever came back on line.  I ended up getting a good quality used one from a parts company in England.  Don't remember the name but they part out old marine engines and were very helpful.  They happened to have an M20 they were just taking apart, same vintage as mine, so I got lucky.  I don't remember the name of the company, but might be able to find it in old emails if it's needed.  All my paperwork went to the buyer when I sold the boat to get the C320.

have any tanks as of April, 2024.  But always worth a try if someone needs
one!
