Help please ,, I am looking at a 2002 and a 2000 39/390 vessel. My question is what is the difference in these years of manufacture. Water leaks transom, deck to hull attachment, swim platform, etc. I have been told that the 390 's were built within the years of 1997 and 2000. What negatives should I be prepared for engine (yanmar),deck, hull, electronics. All input greatly appreciated.
