Hobie 18 age

I am trying to find out the exact age of my 18, and the problem is the ID number of the transom does not seem complete. The id is CCMH7314M, and there should be some numbers after that to identify the year of production, but it is not on either hull. The hulls have not been painted, so the all the numbers are there...but not. icon_eek
So, any ideas?
I am asking this mainly because the 18 may be on the market soon. icon_frown
