Just got a blaster

Yeah thats the one ive got but its 3JM-*****7 but when i try using something to decode it on the iternet it says it should be 17 digits.. :S

This is the motor VIN There is a way to decipher that too let me see if i can find that thread
 
Just reading through the manual, the reason my frame number looks dodgey compared to yours lot is because yours are American/Canadian.. mine are from different places, Japan i would imagine? :P
 
I hope this isn't a repost.. but this is what I dug up.

8th from the far right of the VIN. so for 3 J M - 135387 would be "j" ? 1988
