Hey, I'm looking for some insight into what is causing a continuous beep beep beep in my motor. I talked to a Marina in the area of where we were stranded and he suggested that I pull the cover and disconnect the two wires under the auto(light blue) oilier and if the beep stops, to add 1 pint of oil to 6 gals. of gas and head on back to the dock. I disconnected the two wires and the beep stopped so I did the oil in gas trick and got back home. Water is coming out of the tail tail opening and I was able to place my hand on the engine block when we got back home. The water coming out of the engine is only luke warm. I don't understand why the beeping was still happening after the engine had been off for sufficient time for the engine to cool complete down (if that had been the problem) and before the engine was started. Just sitting with ignition switch on but the motor not running it was still beeping until I disconnected the two light blue wires. Also noticed a brown wire that was disconnected down under the two blue wires. What is it? I think it had a light blue strip on it. Don't have more info on the engine. Boat is a 18ft. bass tracker, 1994 model. Replaced impeller last year. Thanks for any help you can offer.

is it a continuous beep or an intermittant beep?

Re: Merc 60 hp outboard Beep Beep Beep

Welcome to iboats.<br /><br />I'm afraid you need a new oil tank. Beep beep beep is a low oil level warning. Beeeeeeeeep is an overheat warning. There is a float inside the tank with a magnet in it. Either the float doesn't float anymore, or the magnet fell out. No way to service it, you have to replace the tank. You also don't have to worry that the motor isn't getting oil, it is. But that was a proper safety precaution to add oil to the gas until the problem could be determined.<br /><br />Some people simply leave those blue wires disconnected and make sure there is always oil in the tank. For most people, fill the tank when the season begins and it'll last all season. Of course that depends on how much the motor is used. I don't advise this because sooner or later somebody is going to neglect to check the oil and trash the powerhead.<br /><br />The brown wire has a white stripe, it's for a trim gauge. If there isn't one, it can just hang out in the air and not cause any problems.

The beep is not a solid beep, but a intermittant beep beep beep. Not a beeeeeeeeeeeeeeeeeeeeeeeeeep. I know pulling the blue wires killed the beep which sounds like oil related. I just don't know if it means bad sensor or if the oil isn't being sent to the gas. I left the wires disconnected, added oil to the gas so I could get home safely. No problems. Sorry I can't stay connected, will check back later and tomorrow. Thanks.

Since the beeping doesn't stop if the key is on and the engine is off, wouldn't that indicate a bad warning module or something wrong in the wiring?<br /><br />I had that problem last year on one of my engines. New module? Only $200. :mad: That and a few other related incidents are what made me think of premixing the oil/gas and installing a pair of temp gauges. <br /><br />I won't miss that insecure feeling of hoping the engines are getting oil and not running too hot one bit. :)

Could be a bad module.<br /><br />Most I've seen go bad make chirping noises at strange times. Others fail with a constant beep to let the operator know that it failed. If you had a beeeeeeep whenever you had the key on, then you'd have a bad overheat sender or a bad module.<br /><br />Easy enough to test it. Connect the blue wires out of the module together. If the beep beep beep comes and goes with connect and disconnect, the oil half of the module is good. Next ground the tan/blue overheat sender wire. You should get a beeeeep anytime you ground it. That means the overheat side of the module is good. There is actually a third circuit that sounds a constant beeeeep if the module fails, but I can't think of a way to test that. Maybe disconnecting the module's ground?<br /><br />You can test the float switch with a coat hanger. Hook everything back up. Cut the hanger and make a hook to reach in and lift the float. It'll be right above where the blue wires go into the tank. If the beep beep beep goes away when you lift it, then the float isn't floating anymore. Or you could loosen the brackets and turn it upside down, but that could get messy.<br /><br />Let us know the results.
