You may also try taking the HE to a radiator shop to see if what you have is worth fixing?

I'm losing coolant, took it to a shop and they found a crack on the non pressure side, repaired it, seemed to work fine, but over last season I was still losing coolant, but at a much slower rate. I took it back to the shop and they determined that I have another small crack on the pressure side that only leaks when the HE gets hot and the location of it is not reparable. So I'm into a new HE.
Anyone know of a place where I could possibly get a used one? Prices seem to be around $1500 CDN
Thanks Viper, I'll try Wheatley folks!
My advice...get a new one....used, you could be right back in it again, just good money after bad......if you do go new I think I would pressure test after install to make sure all is well.....
Now if you are really flush you could change both and have the good used one cleaned and checked for a spare....

Re: Heat Exchanger Replacement for 8.1 Gas Crusader
A question for the members...
When I purchased my boat, the starboard engine was overheating and we found that the HE on that side had pieces of impeller in there. Apparently the previous owner had impeller issues and they didn't bother to retrieve the pieces. That engine runs about 10 degrees hotter then the port. I retrieved as many pieces as could be found.
As I have changed out the tranny oil and engine oil coolers (due to a failure of tranny oil cooler) this past season, do you folks recommend being proactive and replacing the main engine heat exchangers which are pushing 13 years old? I am concerned about a failure during the season. What do you think?
