Spent the morning test running out diesel engine out and about in front of Douglas Harbor to make sure everything was running smoothly. We filled the coolant tank early in the morning, checked through all the possible problems (of which there were none), called a couple of mechanics to get several opinions and hired one diesel mechanic to come do a thorough check of the engine. End of day result: the motor runs great. The theory from several mechanics, and Clif, is that something (seaweed, kelp, plastic bag..etc) blocked the in-take thru-hole, which in turn overheated the engine and made the coolant boil over, leaving us with very little coolant. After filling the coolant tank with concentrated coolant and fresh water, we were footloose and fancy free.
We took Sound Discovery on a last, long test drive tonight and it motored smoothly. We filled up at the fuel dock downtown about 5 minutes before they closed and motored back to the Douglas harbor. Long story short: we learned some good engine lessons, got another yummy dinner with my parents, and a good-night sleep before REALLY cutting the dock lines.
The weather is supposed to be rainy/windy tomorrow, so haul out the foul-weather gear tonight.
