Finally got my new boat out on the water for more than 5 minutes. Took a ride for about 20 minutes and came back to the dock. An hour later I get in the boat to trailer it. Turn the key, starts, sputters and dies. It just wouldn't start after that no matter what I did. The father in law, ex mechanic, listens to it and say "sounds like it's not getting gas". The light bulb on top of my head turns on. Take a look at the engine and I pour a bit of lake water on the fuel rails. Try to start it again and it fires, but starts running rough and dies after 10 or 20 seconds. Now I'm sure I know whats wrong. I follow the supply line to the fuel pump, get some lake water and pour it on the pump. I turn the key and, like magic, the motor starts and runs as smooth as it ever did. Problem solved.

Thanks to years of going through the various problems and solutions people have posted, I remembered that some of you have had "vapor lock" issues and a little bit of cool water resolved your issues.
