Thanks Bruce! That is a really good plan to follow and narrow down the problem.
If there are other suggestions about boat yards especially around Everett let me know - I might have the boat moored in Everett if slips are available.
I'm looking to buy an 1986 Ericson 32-3 in overall very good shape but with quite a bit of water in the bilge. Since last 2 months have been without rain and the boat has a dripless shaft seal I'm thinking about a possible keel bolts leak. What service yard would you guys recommend for this...
