Colors.....
I looked in the manual and have all the numbers for the RX DI models for that year but I couldn't determine whether or not you can tell by your H.I.N. (hull identification number). If you look at the bottom rear, right side of your footboard, you'll see the H.I.N. plate. The first 3 letters represent the manafacturer, the next five digits (numbers and/or letters) are the serial #, the 9th digit/letter is the month of production followed by the year of production and the last two digits represent the actual year sold for.
If you can't find it on the paper work you have from the purchase, then you may go by the color. That's right, different models have different colors........weird, but they do.
The 947 RX Di series model numbers are: 5583 and 5591, international models and they are blue in color.....5584 manafactured for the U.S are also blue.....5592, 5585 are international models sold in yellow and 5586 in yellow manafactured for the U.S.
I hope this gives you more understanding about the origination and model of your Doo!....anything else?
