Serial Number Help

I have done some looking around before I posted this. My number is CCMP1393M80F ??? I know what most for the numbers and letters mean but I am not sure about the "F" . Please answer this. I looked at my boat yesterday and I am sure it is an "F". This did not make sense compared to what I have read. Please help.

F is the month of manufacture, starting in September (A) of the prior year.

So yours was made in the 6th month (February) of the 1980 model year.

ok.....if F is the month than what does the M stand for? ccmp1393M80f

It's a placeholder character. All the boats of that era (1970's until late '80's) have an M in that position.

You rock! thanks for the help my man.
