You need an OMC/BRP Genuine Parts & Accessories Manual. I have a 2003. It has all of the paint codes and spray can part numbers. Keep in mind the PPG codes are just the color codes. The type of paint you spray is left up to you or your painter. Different people have different equipment. Quick check showed as far back as ’67 for one color. There are some engineering spec numbers for back as far as ’59, but I think that is more for looking at the spray cans to tell if you have the right color. The PPG color code is what you want if you are going to mix your own paint in the type you want to spray.

PS: I found my copy of this valuable guide on Ebay for 9.99 + 3.00 shipping. BRP sells it to a dealer for $10.00. It has all of you carb kits, water pump kits, fuel hose, etc I have heard guys ask about. Individual parts also & Accessories too.
