I'm looking at a 9.9 Nissan motor on Craigslist, and the owner says he bought it used, but the model and serial no. plate is worn down so much that it's unreadable. It's a two-tone, with grey forward and a red stripe, then blue with the 9.9 logo on the blue background. I've got a 9.9 model C, that's solid silver, but when did Nissan change colors? Also, are parts readily available for this age motor?
