Yet, 350 and 400 Verado set the standard for smooth, quiet boating. This video shows how I was able to remove the float, reattach the magnet and reassemble it. I filled the tanks, and the alarm still would go off. I check and there's plenty of oil in the tank. Boat had sit for 4 months after recvd back from Mercury dealer and after 300 hr service. What was the result please? Verado V8 outboards deliver superior fuel economy at cruising speed and wide-open throttle. I take the fuel hose of the fuel pump inlet and squeze the fuel through with the primer bulb of the 3 gal tank till I see green fuel your fuel … concoction coming out, then run the motor for 10 minutes.
Look you will see a extra green wire. I can't seem to find anything on the web. If the engine is running hot and the confidence stream is strong I would first look at the thermostats. This will happen if you allow fuel to sit in the carb for extended periods without running it like over winter. It doesn't have any lights on the dash that can show causes. If they have not been changed in 5 years and you run in a saltwater enviroment they may be shot. A more precise way to check temperature would be to buy an infrared temperature sensor and measure each cylinder head temperature.
I am old school with Mercury motors expecting a beep when the key is turned on before starting the engine. Is it possible on some of the newer ones without that sensor they changed to a metal gear? With many outboard options on the market, identifying the best engine for your current boat can be daunting. Hope you donlt mind me re-igniting this thread as I have exactly the same problem with my 2004 115 Opti and would just about cut off my arms to get it fixed once and for all. Remove the plug and be careful, cause the oil will pour out rapidly causing a mess if your not ready with a container to catch the oil. If the alarm is not coming from the temperature sensor, leave the temperature sensor disconnected and look for other sensors. Threads need to be reorganized and it's taking a long time to rebuild.
Consult your dealer for assistance. I would contact a Mercury dealer to see if the motor in question was included in a recall campaign. Refer to Maintenance — Fuel System for filter removal. That air bubble ,without the main tank hooked up to pressurize the system,is probably the problem. I loosened the cap on the motor oil tank and started the engine with the ears and water on it.
By the way, the cooling system on Mercury motors often needs annual maintenance of the rubber impeller. Cooling System Problem Continuous Engine Guardian System is activated. Thanks, Tom Brown Hey Tom: The first sequence is just a system check,letting you now the warning system is working. Power limit will vary with level of overheat. I got a response off of another topic and this gentleman said he has a 2006 and his has no beep when the key is turned on. The engine is fitted with a 15 P prop.
I was only about a minute from the dock, so started it up again, horn blazing, and got back to dock. Have not been able to find a reference guide for these alarms. Lately, I've been burnishing my way through a new set of skin grafts every couple of days. Apparently this may not be true with this motor? Called Mercury back, talked to a guy, he said sorry for the information from earlier it should not beep. I have never had this happen or ran across it before. Outside of that it of course could be the plugs, water in the gas, or more serious matters but those are less likely. The first one is a four beep sequence while underway and sometimes gear engaged at idle.
It is very likely your alarm is a valid over-temperature alarm and you have a malfunction in the cooling system. Took a look at the oil reserve under the cowel and it looks fine too. Warning Horn Function Sound Description Water in Fuel Four Beeps every 2 Minutes Water in the water separating fuel filter reaches the full level. Regards, Tom Brown To answer the question on starting, it should start fine now. I think that dam thing ran bitchin after I gave it away.
A paint can opener also helped in the removal. So if the alarm begins to make tones that are noticeably different from their normal volume or normal tone, you can suspect that perhaps the alarm itself is having a problem. Is it not the oil line and something else? I have read that this is the low oil pressure. Definitely add oil to the fuel just in case it is an oiling problem. An infrared thermometer is handy for this. Anyway, this repair would be inexpensive to at least try before spending the money on a new tank.
I've had the same problem off and on for two years with one engine. After all, when Mercury made a 1987 motor there was no internet and no forums like this to seek information; you have to assume that Mercury would tell the owner of its motors what those signals mean in their owner's manual literature. If you can solve my problem you'll make an Oz friend for life and I can sleep again! We bled the lines once more and it seemed to remedy the problem, but an hour or so later, the alarm goes off again. Only ran it back to ramp and loaded up. There is a sensor for the oil level in the under-cowling tank. If no water is coming out of the water pump indicator hole or flow is intermittent, stop engine and check water intake holes for obstruction. Took her out yesterday and no alarm - so far so good.
