2004 115 1 beep every 3 seconds and high idle

[Helkel]

Hey have 115 4 stroke. Runs fine, pees well. When get back to dock, idles high @ 1200 rpm and beeps 1x every 3; seconds. I figure some sort of temp issue, any help would be appreciated. No rpm restriction or blinking light or cel when running. Thank you.

Oil change reminder?

[Helkel]

Thanks. I reset the oil reminder. 3 kill switches in 7/10 seconds. No joy. I had just changed the oil.
Working on all water lines now. it sat few a few months maybe the thermostat or pressure switch stuck.

Why do you think it’s over heating?

[Helkel]

Water is hot out of motor pee hole. Plus not sure why else it would idle high in neutral. Runs fine at speed.

Was IAC and weak water pump. Changed both and it is up and running strong. Thanks.
