How to Identify the Model Year of a Yamaha Outboard
- 1). Look on your motor's registration. It may display the year and model, particularly if the motor was previously registered or titled in one of the six states that require a title and registration for outboard motors.
- 2). Look at the manufacturer's statement of origin (MSO). Yamaha provides an MSO with every new motor. Both the motor's model and the year built are part of this form.
- 3). Call the titling/registration office to familiarize yourself with the information needed. Look on the starboard (right) side of the motor bracket to find the MSO placard; both the model and year of production are stamped into the placard.
