Barnacle Buster-Magic Elixir

Hmmmm. Before I bought my "repo boat" I knew it had a temperature creep issue from the sea trial. I was unavailable to do the procedure, so I had a Yanmar "pro" run barnacle buster through the coolant system. Still have the temp creep, only at RPMs I don't use, but it's still there. It could be another more complicated problem with the cooler alignment tubes, but this thread got me thinking.

I'm now realizing that he only ran the BB through the closed, freshwater side and not the raw water side. I guess I didn't realize the raw side could be flushed. Am I understanding this correctly now? The raw side also needs to be flushed?
