Never existed. Engine/Drive parts are motor/drive specific - either Merc or Volvo if we're talking I/O's.
Everything else is off the shelf, assembled by Four Winns. Cup holders, windshield, seats, etc. Go through Iboats if you're looking to upgrade/replace components and use your forum discount.
As previously mentioned engine and outdrive will be from Merc or /VP you can find parts breakdowns on line using your serial numbers.
If you are asking about hull parts, my sea ray came with a parts book for the hull, including wiring diagrams and all parts details. I was also able to get this electronically on line. So if looking for hull parts I would start with Four Winns tech support. The one issue with hull components is that boat manufacturers don't stock the parts very long after the boat is built. So while I may have Sea Ray part number it doesn't mean you can get it from a dealer. It was very helpful because it had supplier details for items like the fuel sender so I was able to order a direct replacement.
