Well, here's the bad news, the Maxum boat line has been discontinued by Brunswick Corp as of 2010. The good news is, Brunswick is still in business and you should be able to get parts from a Sea Ray or Bayliner dealer. Go to Maxumcustomercare.com to get the part numbers you need and cross reference them to the new USMarine number here: http://www.baylinerparts.com/xref.pdf
before contacting the dealer.
If you are looking for seats for that year boat, Brunswick will no longer have them anyway, so you will have to find an upholsterer or contact the private places that purchased the Maxum patterns
