1995 40hp oil injection buzzer

[armentroutkt]

I want to apologize in advance if I'm kicking a dead horse on this subject. I have read an overwhelming amount of information on this forum and am having a hard time deciphering what tests I should try first. Sorry for my ignorance.

1995 Mercury tracker 40hp

When I turn the key, yep you guessed it..beep beep beep beep non stop. Not a continuous beeeeeeep.

I opened up the electric box to see if anything looked out of whack. Sure enough the voltage regulator looked like someone tossed some thermite on it!! LOL. I replaced that hoping that might have something to do with the oil sensor. NOT!

So I moved on to the tank. I read somewhere in here to flip the tank upside down to see if it would stop... no luck. I tried something a little different. I took the sensor out of the tank, filled up a cup with oil and put the sensor in the cup. NO BUZZER, just the initial beep when the key is turned on. I put the sensor back in the tank and filled. BEEP BEEP BEEP continuous. Does this mean the tank is bad? Or the float inside he tank??? Any suggestions?

Thanks again!

I ordered a tank. So we'll see if this fixes the problem. I'm surprised nobody has any input??

Re: 1995 40hp oil injection buzzer

I have a 2 stroke I bought off someone and it needed all wiring then he bought me a 1997 40 HP 4 stroke oil injected engine. I couldn,t use any parts off that engine, but i did strip the crap out of it to sell on eBay. I got 30.00 for the oil tank the parts i have left are a stator tested with an ohm meter flywheel fuel solenoid stator adaptor and a major electrical unit i have no idea what it does . I sold the switchbox regulator and the oil warnign sensor, but i still have the oil injection pump. The motor died from lack of oil. I,m sorry about your delema but please do get thet warning sensor fixed. If any of the parts I still have may help email me and i,ll surely let you have it real cheap. I,d hate to see your engine end up like that one did.

Re: 1995 40hp oil injection buzzer

Thanks Maxz695

I appreciate your response. Hopefully the oil resevoir will come in this week. I guess $50 wasn't too bad if this fixes the problem. I picked up the motor for $500 so I reall can't complain I guess. I really didn't want to disconnect the oil injection, just SCARES the poo out of me wondering if it's going to fail.

If this doesn't fix the problem, I'll be knockin! Thanks

Re: 1995 40hp oil injection buzzer

G'day,if you intend keeping the motor, get a manual (priceless).Had the same prob with my merc.Took me through many tests.When you took cap off oil res,was it full to the rim.if not it needs to be.

Hey aussieflash,

I did fill the tank up and the buzzer kept on gettn it. I just received my manual today from Bustersmarine. Cheapest I could find for under $30 + free shipping!

I was suppose to receive my new oil tank today, but it didn't come. Hopefully Monday it will be here. If this oil tank doesn't fix it, I really don't want to spend anymore time or money trying to troubleshoot this thing. I've always pre-mixed my gas before, mainly cause I'm too broke to buy a 4-stroke:facepalm:

I've read on another forum that you can disconnect the tank and remove it. Take the inlet and outlet lines coming from the oil pump and connect a tee between them. Disconnect the tee for the gas line and route it directly. From reading the manual, seems it has an oil pump gear that runs off the crankshaft. I guess it needs to get lubrication and the crankcase also has to have a certain amount of pressure for the bottom to cylinders?.

It would be nice to get a block off plate and do it the right way. I havn't hear anyone mention one of these kits for a 40hp merc? Have U?

Re: 1995 40hp oil injection buzzer

no i,m not that informed on the system itself but there is a drive for the oil pump that is nylon i believe and they do get chewed up this will affect the pump. might want to peek at it.also I rad today that there may be a float in the oil tank that sometimes comes unglued. are you getting the cap with the tank because I think thats where the sensor is

 

[armentroutkt]

Re: 1995 40hp oil injection buzzer

I read that too about the float. The sensor in this oil tank in underneath. Theres a little phillps head screw that holds it in place. I did unscrew it and slid it out. It had two wires (Ithink blue/white and blue) If you unplug one of them the buzzing will stop. The cap itself doesn't have anything in it. It just unscrews from the tank. You can pull it out. It's held in kind of like a chainsaw gas cap. Just a tee on the bottom. I'll bet that shaft is cheap ol nylon. Why in the world?! I've hear of these getting chewed up and causing some damage.

Re: 1995 40hp oil injection buzzer

there was a post earlier describing the blue and wht wires and if the buzzing stope that it explains what it was search back early tody to find the post that may help you heres what I got might help --> Re: mercury overheating i think
Sheesh.........

The alarm circuit is comprised of an alert noisemaker or light connected to key switch power, and to a wire that goes to a terminal on the starboard side of the engine just above the switchboxes. On that terminal are 3 wires. One to the alarm, one to the overheat sensor, and one to the oil alert.

Take off the wires to the overheat sensor and the oil alarm and turn on the key.
>>> still noise, there's a short to ground in that wire to the alarm.
else
connect the other wires back one at a time. The one that sounds the alarm goes to the defective part.

Hope it helps

Hi Chop,If you have disconnected your overheat sensor and it still beeps when key is on,then you have a faulty warning module...replace module. Reply Reply With Quote .

Disconnect at the terminal strip I told you about. If the oil module and the temp sensor are both disconnected and it still beeps, the wiring is shorted.

Re: 1995 40hp oil injection buzzer

Try removing the negative cable from the battery and then reconnect by a chance it may stop not likely but some sensors will reset after this proceedure. It sounds more like a grounded wire though because the engine isn,t running and you get the alarm. But hold on to hope that the new tank will solve the problem

Re: 1995 40hp oil injection buzzer

after re reading your post you said when you unhooke the float sensor it stoped that means the tank sensor should be to blame. sorry tierd been helpng most of the day and working on my own issues out on the engine

 

[Maxz695]

Re: 1995 40hp oil injection buzzer

the float sensor is no more than a switch that when the level drops the switch goes on and when it reaches a certain point goes back off to test this theory connect the blue and white wires together the alarm should sound and when removed it should go off this means the sensor itself has a short and not oncommon from this setup from what I here

Re: 1995 40hp oil injection buzzer

Thanks Max,

Thats what I was hoping you would say! Hopefully come Monday when I get the tank I put her on at the buzzer will only sound once when I turn the key on. The more I read and looking on ebay at all the parts for 40hp mercs parting out due to powerhead failure because of something went faulty on the oil injection system the more I'm getting worried about even hooking it up. I don't know if it was due to people ignoring warning signs if any or what. Just kind of worried, that's all.

Thanks for all you input, it's greatly appreciated!

Re: 1995 40hp oil injection buzzer

Hey Max,

What problems are you having with your motor? Is it the same motor. I just got my manual in if you need me to reference anything for you or scan a page out of it?

 

[Maxz695]

Re: 1995 40hp oil injection buzzer

Not to worry at all in there is no warning sensor sound that means all is goooood to go GL

Re: 1995 40hp oil injection buzzer

Hey Max,

I finally got the oil resevoir today!!!! Snail mail finally delivered it. I installed the tank, and with no oil in it... beep beep beep beep. Turned off the key, filled with oil, turned the key and only beeped once. Seems to be fixed.

I disconnected the output tee connector where the fuel meets the oil, capped off the tee, ran 50:1 through it and extended the oil pump outlet hose down into a cup. After running it for about 2 minutes, I could see the oil starting to push through the tube like a snail. I put a freakin 2 foot hose on it so it took forever to work it's way down into the cup. Once it stabilized, I tapped the throttle just a little over idle. I counted every three mississippi and one drip would come out. I AM SOOOO NERVOUS relying on this thing to keep my motor oiled up. Will this thing warn me if something fails. Just how reliable is this system?

On the down side, I've got 12 gallons of mixed fuel I guess I'll have to use somewhere else.

Do you or anyone else have any thoughts on this? To bypass or not to bypass. I know it sounds dumb after I fix this thing to bypass it all together. I'm just rambling now. What are your thoughts?

you should be able to bleed it somewhere there was a process ebtered earlier today on just that issue But yes run Premix oil fuel until this line is bleeded out Congrats on the fix now take your time and look for the bleeder you may have to disconect the oil hose from the engine to get it to move faster and the pump need oil it,s not primed so if you take a container of premix ud use that to feed you shaould be ok i,ll try to find the post and send you the link

Re: 1995 40hp oil injection buzzer

Fill both reservoir and remote oil tank.Loosen res tank lid 1/2 to 3/4 turn,Start engine...air should purge from lid.Have rag ready and tighten when oil starts to overflow.Make sure remote oil tank is sealed and tight.
Also to make sure,you can bleed air from pump and outlet hose by loosening bleed screw on pump 3 or so turns and allow oil to flow for a moment.(do this with ENGINE OFF).Now you can be sure your pump is full of oil. bleed the pump first then the resivior

Re: 1995 40hp oil injection buzzer

Hey Max,

I'll check for the bleed screw tomorrow. I couldn't find anywhere in the book the procedure to bleed this particular motor. It just said, make sure when you disconnect any oil lines you bleed the system. Gee, thanks. I did see some air bubbles come out when I was running the oil into a container, but it sounds like your suppose to bleed it after everything is hooked up. I'll check again tomorrow. Also I'll take some pics. As for the 12 gallons of pre-mix, I guess I'll just keep adding straight gas to it. I don't guess it will hurt it running that much oil through it, probably just smoke like a chimney and possibly foul a plug?
Thanks again
