Hey Ralph at the onset of the leak it was leaving a puddle the size of a dinner plate after running for 5 minutes.Have got it down to a PITA leak pretty much now.Ran it today for a quick ten minute ride had just a small amount seeping out from the drain channel not enough to even drip.I think the Bars Leak would work for a rad pinhole leak but the hose connections is something else.Check you later getting the boat and gear ready for fishing tomorrow.See Ya!Can you use Bars Leak or Ironrite for such a small PITA leak?
