I just bought a boat 3wks ago and it looks exactly like yours. Ours is a 1993 21ft LX Century bowrider. The color is the same as well. I have the original paperwork and lots of info although our trailer did not come with the boat. It was purchased a few yrs ago. I would be happy to share any info you need and I would also like to see a picture of your trailer showing the bunks.
Please post a pic of your century. I would like to see it.
