I am looking seriously at a '79 Irwin 30. We went over her and she needs mostly cosmetic work. The only thing we have found is a semi-soft/rotted compression post and the bulk head attached to it. Are there any other specific quirky Irwin things that should be addressed before a final offer is made? She has also a Yanmar diesel. Anything to watch out for here? My last boat was equiped with a tired OMC saildrive. Try finding specific parts for that. Thanks in advance, Scott
