I bought a motor today and was looking for the serial number and couldnt find it. I looked on the motor and on the transom bracket and found nothing. But looked like there had been a sticker on the port side of the transom bracket, just wore off i guess. Is there any other way to figure out the information for this motor: serial number, year,etc? It looks to be a slightly older model and all i know is that it is a 6 h.p. evinrude.
Sometimes there is a quarter coin sized aluminum plug on the engine block that has numbers or a model number stamped onto it. A missing serial number tag on a used motor could be a red flag for a stolen motor or it could be just something that happened.
Another way to determine the year is to post pictures of the engine front, back and each side both with and without the motor cover and we may be able to narrow the year down close for you.
That appears to be a 1987 6hp.
