Egg on your face, wipe it off with a napkin and move on.
Even us 'Older Guys' have our times. As a Retired lifetime mechanic my lawn mower wouldn't start the other day, only firing on one cyl and dying. I checked spark, fair, spark plugs slightly blackened. I went ahead and changed them both anyway. Still only fired on the front cyl and died. I tried spraying carb cleaner in it while cranking. It occasionally fired both, then only the front and died. I was perplexed.
Until I lifted the gas cap.
D'oh! I KNEW the gauge fuse was blown, I hadn't taken the time to cure that issue. I have since.
So spit happens, forget about it and go enjoy your boat.
