I have a 1991 150 Yamaha on a Grady White. On several occasions recently I would try to start the engine and it would just crank over. I figured out that if I moved the kill switch / key a little, the engine would fire right up. Presume the switch is the problem and want to replace it before it creates a major problem. How do I remove the switch from the shifter? I won't get to the boat for a few more days, but I'd like to have a plan. As I recall there are 2-3 screws on the face of the shifter. Do I remove those? I'd rather get some advice before I start just unscrewing stuff. Not quite sure if I'll replace with an aftermarket dash mounted switch or opt for an OEM replacement - and I don't just want to bypass it. Price and availability will probably determine that. Thanks in advance for ANY help you can provide.
