I am new to the club and this is my first post. I will apologize up front for any misnomers or boating faux-pas.
I am looking at a potential purchase of a 1970 31 Commander convertible. The boat has been on the hard for at least the last 12 months. It has original 327 engines with approximately 900 on the port engine and 1100 on the starboard. The interior is original as well - in decent shape for a 49 year old boat. It has been in fresh water its entire life. This is my first boat purchase - we have been fortunate to have "friends with boats" for many years... :-) . From my research, the Commanders appear to be very well made and hold up well with good care / maintenance. I have restored numerous cars, so understand the mechanicals, but boat structure and fiberglass are relatively new for me.
This particular boat definitely needs bottom paint, and a good clean / wax. The engines fire up and run. My concerns are with the overall structure and integrity of the hull, deck and cabin. The gunwale on the starboard side of the cabin (approx. forward window) flexes and makes a noticeable creaking sound when you step on it. This is the area where the strap from the crane went when the boat was taken out of the water and placed on the hard. The door to the cabin does not close. The door overlaps the door frame by about 1/4 inch. Are these major issues that indicate bigger problems? The yard says the door problem "Could be do to placement on the hard". Is that reasonable? It
Additionally, the areas where the shafts go through the hull look to be covered in grease or oil, is this normal? (I have posted a picture of this area).
I appreciate any guidance or assistance you can provide.
