I have a 2003 200HO on a 519vx with keypad ignition. Engine has been running great until late yesterday when I went to change spots it would crank for several seconds then make a spinning sound and not start. Voltage was good and I tried it 10 times and it kept doing it. I went to bulb and gave it a few pumps, it seemed hard enough, then I took shifter out of gear and tried that and it roared to life.
I finished the day close to the ramp starting the engine several times and it fired right up. Talked to a guy at the ramp and he mentioned it could be " vapor lock" which I have never heard of. Thoughts?
