how to decode Tohatsu motor serial numbers

[mudchuck]

I've got an M40C which has the 361A - 67302 S/N
How can I determine what year this motor is?

SN is 67302. Made from about 1992 to about 2004. Year is irrelevant for servicing, but if curious, call Tohatsu America at 469-771-3740. Only the newer serials (not yours) have the year of manufacture in the serial.

Thanks Paul, I called they told me 1990, which is slightly better than I thought as I was told by the PO that it's 1987.
