I am having difficulty in identifying the year of a yamaha outboard engine. The model is yamaha 50 DETO, 3 cylinder, 2 stroke autolube. The plate on the engine says 6HS L 506066. Any help that can be given would be appreciated.
Probably have to call the manufacturer and give them the serial number. They all have a list of at least one of the owners of the motor and they can give you the year.
