Can anyone tell me what year motor I have? My boat is a 1985 Montauk 17' The only thing I know is that its a 2 stroke 90 hp Yamaha. Any info would be greatly appreciated. Sean

You need to find the serial number. Look for it stamped into a freeze plug.

Yes, that's the serial number. We need the model prefix too but the decal on the motor brackets where that was is long gone.

Still there may be a list somewhere with the serial portion of the number. I'll see if I can find it.
