I just bought a jet ski. I find that my key keeps slipping out when I'm driving. You know how there is a green starter button, and then you slip your key on the red button to keep the machine running? What is the key called that you put over it? is there a way that you can replace that key? I mean is it something that you can find on ebay? or do you have to specifically buy it from whatever company your jet ski is made by? BTW... what is that key called?
