Hi all,i'm trying to find the year of a motor i've just bought,it's a evinrude 25hp commercial,twin cylinder,2 stroke long shaft,thru prop exhaust.The model and serial number sticker is missing from the mounting bracket,there is a number on the engine core plug which is G39939.From looking at pictures of others on the internet it looks like a model from the nineties but not sure.I would like to know if there is anywhere else i can look for the model number?.Thanks in advance for any help.
