Last Sunday, replaced one of my batteries, fuel filter/separator, fuel line & primer bulb. Greatly improved cold starts to 1st or 2nd crank. Monday, out with family on the river, ran it up to 5k rpm. At speed for about a minute, and I get an audible alarm from inside the console, and it starts running a little rough. I stop, shut it down, wait a few seconds, restart, and it runs fine afterwards. What was the alarm for??
