I have a yamaha 9.9 that I have had for a long time and I dropped it and broke the tiller arm off of it and the bracket that holds it. Anyway my question is how do I find the year of the motor so I can buy replacemnet parts I have yet to find the model number on it. If it is any help the motor is light grey manual start 2 stroke and shifts on the side. Any help would be greatly appreciated. Thanks
