Johnson VRO help

[Embrey]

The every one second beep (oil) has been going off occasionally for the last year when I first start at the ramp. I turn off and on the motor a couple times and it goes away.

Last time I could not run the engine at idle very long before the every one second alarm would go off. I have read where sometimes this can be caused by other things than a bad vro pump.

I guess the immediate question is , do need to cap the oil intake to run the engine with 50:1 mix. Was hopin to go fishin tomorrow. Figured I could disable the vro and run 50:1...maybe trouble shoot to see if it is the actual pump that is bad on another day.

yeah, but that may not help with your alarm issue if thats not what is causing it.

i just replaced a pump on my cousins 150 johnson,did the same thing for about the last year at first start up the alarm would go off,sometime.If you pumped the oil bulb it would go off and stayed off,in the beginning.recently it finally got to where it would come on at idle all time,then i'd pump it up and it stayed off while running higher rpm.after replacing it has stayed off.i'd say the diaphram had a tear in it and it wouldn't hold pressure.you may look on bassboat central i found his for right at $100 shipped to me off a blowed motor.if you pre mix you need to cap the oil line and unplug the alarm harness.it runs off pulses from the crankcase there fore it will try to pump when the motor is running it pumps air in the fuel system.
as Embry said you need to make sure that is what it is,you can unplug the vro and see if it quits,if not unplug the wire to the tank see if the low oil sensor is bad,then unhook and ground the head temp wires.whatever you unhook that makes it quit is the culprit.
