I know this has been asked before but my problem seems to be a bit different. I took my boat out for the first time yesterday. 2008 Rinker EC with a Mercruiser 6.2 Horizon. At idle I am getting two beeps every two minutes. Once I get the boat to about 3200 rpms it will sound the solid buzzer. If I power down it returns to the two times every two minutes. All fluids are good and all gauges are looking perfect. I had it started in my slip last week for about 15 minutes with no buzzers at all. I did top off my lower unit reservoir before stating it yesterday. I have read many post from others with similar issues but not the same. I have ordered a IAC valve just incase that is the problem but the boat idles and runs fine. I have also seen some post that suggest cleaning out the lower unit reservoir. My marina wants $125 just to send someone down to the dock to pug in a code reader. Has anyone had this same issue?
