Re: 90 hp johnson beeping when engine runs 3 - 4 minutes
All we know is that you have a 90 HP Johnson. It was made in a specific year so that would be handy to know. We also have no idea what the beeping sound is and that is important since there are several tones associated with the alarm system. So 1) what year engine, 2) has the oil injection system been removed and/or disabled 3) what does this beeping sound like a: constant beep, b) beep-beep-beep at regular intervals, or a c) a beep every 20 seconds or so. If its a constant beep that's an overheat situation. Beeping that is on-off-on-off, etc., are oil related alrams.
