A setback

Well, we took Queequeg out for a half-day shakedown on Sunday. It was a beautiful day, ESE winds at about 10, lots of sun, etc. We had a great time sailing under jib alone with Bev quickly learning to handle the jib sheets. We came back to the mooring and picked up the ball easily. All was wonderful BUT...
Upon checking the engine afterward I found that the fresh water coolant had all leaked out. Investigating this today I discovered that the heat exchanger was bad. Yuck! I had no idea these little gizmos were so expensive! First of all the manufacturer, "Sen-Dure," no longer stocks this particular model. They very graciously said they could make one (they still have the specs on file) but it will cost $650 plus shipping. This is WAY out of our budget. So it looks like we sill be stuck in the harbor until 1) a rich relative neither of us knows about dies and leaves us money OR 2) we save up the bucks to buy it OR 3) some kind person reading this blog hits the "Donate" button and helps us out.
Our only real hope of a timely, reasonable cost solution will be if the local radiator shop can repair the unit. That will be tomorrow's project. Wish us luck.
