" I have a Yamaha Stern Drive I/O. Until last week, it has not ever give a hint of trouble. Last week, I ran the boat for 20 minutes or so. Then, I pulled the throttle back to idle, and the boat stalled. It would not start back. I got the boat home, the next day, I hooked it up to a hose to run it at home, it cranked, ran and when I pulled it back to idle, it cut off and wouldn't restart for 3 or 4 hours. I replaced the plugs, fuel filter and drained the fuel bowl from under the fuel pump. Any suggestions? "

" Probably the same thing I am going through on my 4.3 sterndrive. There is an ignition cutoff switch located where the throttle/shift cables attach to the motor. On that bracket there should be a cam assembly which trips a microswitch under throttle in gear. if that is bad or not centered in the cam, it will act just like you described, usually only when you throttle down out of forward or reverse.
