We bought a 1986 boat with a Westerbeke W-33 with about 3300 hours. Engine sea-tested ok, but subsequent starting problems in the Fall led to the discovery of low compression and to a complete rebuild. Use $10,000 as a ballpark. Always get a compression test with an engine survy before purchasing(darn!).
