2006 sv 211 team heat exchange replacement.

[Castillo530]

So we recently purchased a 2006 nautique 211 team and it has a heat exchanger in it since it was a salt water boat, I want to remove it and replace it back to fresh water cooling I am having trouble finding the parts needed. It has the 330 xcalibur gm engine! Any help would be greatly appreciated.

Curious why you would change away from a closed cooling system - the antifreeze protects your block from corrosion

Well it was a old system installed with the boat when it was first purchased, and then sat for a few years, I am the second owner I took it off because I was having overheating issues I first changed the impeller and it’s still over heating , after I took out the heat exchange and it looked so rusty and clogged up so I just wanted to basically put it back to stock . I just need help finding these parts to get it back together.
