Hello. I have a Mariner 55hp outboard the serial number is 55 EL 663 L 318670. Im trying to locate a wiring diagram and I am interested in what year it is but to my understanding thats not too important with this one as the are mechanical the same as the other models from different years.

Looks to be circa 1988.

Does the motor have automatic oil injection or not? If not, it may be very similar to a Yamaha 1991 CV55ELRP model.

Look at any markings on the CDI assembly and the carburetors. See if they agree with what the Yamaha parts catalog shows for those components.

Service manual, which contains the wiring diagram, is available from www.yamahapubs.com
