I began this thread in September. Bought a sailboat, barely knowing anything about boats or sailing. The boat sat in waiting for three years. I've managed to bring her back to life and sail her to her new home for this season. This is one of the most satisfying views I have ever seen.

Congratulations J. on your impressive new skills and accomplishments!
I'm in the process of re-hab'ing an '82 C30 that except for several outings under power, lay dockside for seven years. Fortunately the MD5411 diesel was running fairly well, needing only new oil, filters, thermostat, and restoring the bypass loop in the cooling system to reach a decent operating temp. in the 55 deg. Monterey Bay waters.
I'll second Ggrizzard's comment regarding "babying" the engine once the initial run-in is over. Not only mixing elbow clogging issues, but also coking-up of the exhaust valves if exhaust temp. is kept low, with prolonged charging at low RPM's or running well below the 80% of max RPM level (2400 of the 3000 max. in the MD11) that usually prevents this. A diesel with "kid glove" treatment over time may well not to have the the power needed in a tough chance at sea.
For this and the six prior diesels, I've made a practice of running a short bit at WOT before anchorage or marina approach - something a Yanmar tech. recommended years ago.
