VRO oiler on older 90 hp Johnson

[Timber]

I have a 1985 90 hp Johnson I just bought, with VRO on it. I've heard/read so many scarey stories about the VRO not working properly, I am wondering if I should disable it and just mix oil with the gas. Would this be the thing to do, and is it difficult to do?

[Valv]

That would be the first thing I would do. Just dump the oil tank, plug motor oil inlet, and disconnect harness to alarm ( I forgot which color are the wires, but I know somebody will add to this)

Mix your gas 50:1 and you'll be a happy camper.

There were several updates to the VRO system made over the years. To make a long story short I replaced the pump and pulse sensor and was still paranoid about it so I mixed the gas until I sold the boat.

If you have the latest pump and fittings and there are no air leaks in the system you
"should" be ok is what I was told.

Do you feel lucky ?

If you still need info on how to disable it post again.

I did disable the VRO. Disconnected the oil line and capped it. Disconnected the electrical wires. Then mixed the oil and gas at 50 to 1. But had one problem. An alarm went off while "underway". A beep, beep, beep from under my console. I assumed it was a sensor that the oil pump wasn't pumping oil, but I know there is oil mixed with the gas. I found the alarm and disconnected it. Everything seems fine. Am I doing anything wrong here?

[Valv]

I believe the alarm might be for overheating also.
If water pump is new and motor doesn't overheat, I wouldn't worry much, but I would disconnect harness at motor and reconnect alarm on remote, just in case.
I forgot which wires color it is, maybe somebody here will help you.

On my motor the vro was mounted on top of the fuel pump (they look alot alike).

Disconnect your oil line at motor and cap with rubber plug and clamp, then mix oil at 50 to 1 .
If alarm sounds disconnect tan wire at VRO pump.

If you have the owners manual there is a section that explains the beep patterns of the alarm. As Valv mentioned the alarm is not only for the VRO so it would be best to only disconnect the vro rather than the alarm.

Can I disconnect the "tan" wire at the "horn" rather than the motor? Not sure how to do it at the motor.

[Valv]

Timber, I don't want to sound "aggressive" but you better follow the suggestions, I don't think the one on buzzer is correct wire, check inside motor area, you will find the wire.

You have to understand we can give a limited help here, not being there to test.
What happens if we tell you to disconnect it at alarm, and motor blows up due to overheating since buzzer didn't work ?

My suggestion would be to return everything back to stock. The VRO regulates the amount of oil oyu engine uses at different speeds. Maybe I have been lucky, but I haven't had any problems. The oil alarm should sound everytime you start your engine to let you know it is operational. I might be an fool, but I trust the engineers that designed this unit and I trust it will work providing I use quality oil and check its operation periodically.
