1994 Yamaha Pro 60 Oil injection Warning Buzzer

8 posts in this topic

The oil reservoir is full and the warning buzzer will sound after the motor has been running for a short period of time. I will shut the motor down, wait for a while, re-start the motor and the buzzer will stop. This may or may not repeat itself.

What do I do to solve this problem?

Thanks for the help.

Are you sure it's the oil buzzer and not a overheat buzzer?

Good question!!

would the overheat and low oil buzzer sound the same?

The motor is shooting a good stream of water so that would tell me it should not be over heating.

But then I am not a mechanic. smile

I am not a mechanic so take it for what its worth. Have you attempted to leave the motor running to see if the warning buzzer goes off? How did you come to the conclusion that it was your oil inj warning buzzer? If indeed it is than it is most likely the oil sensor in the VRO assuming this is what you are equipped with. I have a bad oil sensor on mine that I will disconnect when I get time, I stopped using the oil injection and now mix my gas/oil. I researched the heck out of this before attempting any home remedy, I got thee suggestions from dealer mechanics and SEVERAL others with same issues. One other thing to look for is that your motor is indeed using oil out of that reservoir as the oil injector itself is notorious for failing. Mine is also a Johnson 70 Hp but all the same evil as much as I have read.

Hey barebackjack, On your 70 Jonny, does your tach work correctly? I had issues where my tach stopped working, the VRO alarm kept going off and the battery would discharge (The tach and VRO pump get their signal from the same lead). Turned out to be a bad armature. Replaced the armature and the problem's gone. Phred52

Tach is working fine. Once I disconnect the oil sensor and that alarm light doesnt go off I might be giving you a holler, thats a new one to me, one of MANY! Seems to me these VRO's should be wired to run solely, not combined with other instruments. I like the idea of knowing that my oil is mixed VS wondering.

What kind of buzzer is it? Continuous, or intermittent?

Also, what kind of operations are you doing before it starts to buzz?

Yamaha and OMC's oil injection systems are NOT the same. Try diconnecting both oil res, then the overheat sensor in the cylinder head to see which one it is.

    • The very fact that these drugs are illegal keeps the prices so high, there is a huge risk for anyone dealing them so they need to make a boat load of money for it to be worth the risk. Legalizing things always brings down the prices and makes the black market $$$ not worth the effort.
      Considering the psychedelics are the most harmless group of drugs out there then by all means go for it. This is exactly what I mean when talking about legalization, public opinion in this country is so far away from the actual science it is kind of scary. Heck when prohibition was rocking pot was 100% legal here, just think about that for a second. There is almost no rhyme or reason to many of our laws you are a shining example of that.
    •   The "war on drugs", by which I take it you mean keeping them illegal (feel free to correct me if that is not your meaning) reduces the opportunity and raises the price for addictive drugs.   There are perhaps other policies that might work, but treating Heroin or Cocaine like ibuprofin doesn't seem like a good idea.     So, what do you mean by "end the war on drugs".   Go Colorado for "hard drugs"?   Treat them like California does alcohol (sold in every grocery store, and some convenience stores)?  Make them prescription?   Decriminalize possession of small amounts? 
    •     You judge everyone by their race and religion ?      
    • Years ago brother and I at our hunting cabin for a few days of grouse hunting.  Second morning we up and at 'em just as grey dawn settling down on the woods.  We hunted up and down the hills and through the brush and brambles seeking an explosive brown ball leaping skyward. Nothing. Not a feather seen. Later, after breakfast and chores ,brother sitting in the little outhouse with the door open,  enjoying the warmth of the sunrise and contemplating life in the woods when with a flutter and a cluck-cluck,  a nice big grouse landed on a small bush about five feet in front of the outhouse. Brother looks at grouse;  grouse looks at brother. They spent   time examining each other until my brother made a move and the grouse disappeared. We didn't see him around the place for the rest of our stay.   But we found some of his cousins.
    •   Uh, no. You have stated that people should prove their own claims. I don't have the time or the inkling to go through thousands of posts to "prove" it to you so I guess it's just fake news.
    •   Uh, no.   I believe I said that people should post attributions of stuff they quote.   
    •   I could post a certain song by Aerosmith, but I won't......    And yer dang right I'm gonna!
    •   1. He's one of those scary brown people 2. He's a scary Mooslim, not a god fearing Christian 3. Donald Trump sort of likes him.       How would I know? You're the one who brought it up. I thought you always said that it is the obligation of the poster to prove the facts that they post?
