I have searched high and low for an alternate to the Heatercraft replacement core for the 300H heater, the long rectangular 3 hose one. There is a lot written about the 200 series, with the cheap replacement for that available at Napa and other places. That one is more square, where the 300 series core is 16" X 6" X 2". I got the boat cheap, been fixing a lot of things on it, now is the time for the heater to work so the wife and kids will still want to come in the boat! I took it to a local radiator shop, they repaired a half dozen areas but kept finding leaks, so the core is shot. Guessing previous owner didn't winterize it right. Same with the shower, need a new pump for that, easy to find those. So anyways, if someone knows of a replacement core for the 300H that would be great. I will pay the high price from Heatercraft if needed, but only if there are no other alternatives. I checked MC Teamtalk and a bunch of other websites, no one seems to have figured this one out. Or I somehow missed it! I'll post over there as well.
Thanks,
Kevin
