Hi forum members, the key switch on my older Yamaha 703 control box broke up when the plastic failed. I never thought there could be so many little parts and springs in such a small space as the keyhole. The switch has 3 positions, Off, On, Start. The electric choke solenoid is operated with a toggle switch below the key. Is there a universal replacement part or are there variations? Any tips on the process is appreciated. The engine is an older 1984, 200hp, so the 703 is vintage as well and showing it's age, like me.
