Yamaha 200ETXJ 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 kind of problem will give me an audible alarm. This is my 1st boat, and the previous owner didn't say anything about alarms.
