Hello All,
I just purchased a 1996 Johnson Ocean Pro. Background, I did a compression test all ok. changed the plugs proper gap, oil water seperator changed, in line filter changed, new hose clamps. My problem is the motor can't be set to anything below 1000 rpms for a idle or it stalls when put in gear after warm up also I get a low oil alarm with the beeps every few seconds on any rpms over 4800. I was leaning towards the vro pump, because of the 2 factors which I had mentioned. Before diving deep into my pocket, I was looking for some confirmations to my thoughts. What ya Think??:rolleyes:

you could have dirty low speed carb jets, causing you idle problem. clean the oil tank an lines. then refill, and before connecting to pump, prime the hose till you get just oil, no air. then connect to pump.

Why are you trying to drop the motor idle speed? 1100 rpm's is the setting for the idle on the motor. If you are concerned about the high speed "shift" into gear from 1000+ rpm's your motor has "shift assist" installed that temporarily stops the motor from firing when you shift it into gear so there is no hard BANG into gear.

And with my motor, I disconnected the VRO pump and I add the oil to the gas now and it runs fine and dandy. There is nothing quite like being 30 miles offshore and the VRO pump quits ....

Just to clear up a few things - a 1996 225 does not have a VRO, it's an OMS pump. Quite different.

The idle should be around 900 or so in neutral when in the water. Out of the water it'll be about 1000-1100.

The shift assist only works coming out of gear going into neutral. Not going into gear from neutral.

Hi guys,
Does anyone know the part number for the VRO/OMS pump? I still have that issue with the alarm sounding for low oil above 4800 RPM's, so between that and the low idle stalling Iam looking into purchasing a new pump.

Does anyone know if the part number for a 1996 225 Johnson is 5007420, and if I'm heading in the right direction????
Thanks!!!

Wouldn't the low oil alarm (a beep every ~10 to 20 seconds) be from the sensor at the oil tank rather than the fuel pump... therefore indicating a problem at the tank rather than the pump? I can't give any advice on your idling problem, but if I recall, the low oil alarm sensor is located in the tank and the no oil alarm (more urgent, a beep every second or so) is located at the pump.

As for the part number, you can go to brp.com and do a parts search based on the year, hp and model number of your engine.

Warre, If that motor is like my '98 Johnny 150, there is a fuel restriction alarm, as well as low oil, no oil and overheat alarms. Before you replace the OMS pump, you might like to figre out exactly what alarm is activated. BTW - a fuel restriction would tend to occur at high throttle settings, which is what you are seeing.

Re: 1996 225 Ocean Pro VRO????

Thanks All, you guys are definitely looking to save me some money:D
I'm still learning the warning signals on the motor, what does a oil restriction sound like???? Maybe this will narrow down the alarm above 4800 RPMs. I just raised the idle to 900-1000 in neutral the water, I'll let you know how I make out with the stalling in gear:cool:
Thanks Again!

You obviously don't have an owner's manual. That's my first recommendation, get one. They are available at various places. This will tell you all the operator and maintenance stuff you need to know. If you want to go further
to work on it, I further recommend an OEM service manual.

Second, anywhere that sells Johnson/Evinrude OEM parts can order you a little dashboard label that tells you what the warning alarms are for. I put one on my dashboard this year. Or you can make one yourself.

Single Beep on start up - normal test beep

Beep every second or so: "No Oil", which means inadequate or no oil is reaching the OMS/VRO fuel pump where oil and fuel are mixed. This is an urgent sounding alarm. Sensor is at fuel pump

Beep every 10-20 seconds or so: "Low oil" which means the oil tank is getting low. This is a less urgent sounding beep. Sensor is in oil tank.

Constant beep can mean two things: overheat or fuel restriction. The difference is that the fuel restriction generally happens at higher RPMs and stops quickly after you back off. Overheat sounds the same, but won't go away until the engine actually cools off.

Again, get some information on your engine so these things are clear to you.

Don't you have the "System Check Engine Monitor" on that engine? If so you don't have beep codes. The horn will sound for 10 seconds and the LED will light and tell what the problem is.

If your getting a low oil alarm it's the sensor in the tank.

Thanks All! I have the idle problem corrected, engine is running good at a idle. However I still have an issue with the oil alarm and light every few seconds above 4600 RPM's. I have changed out the all fuel filters, line, bulb, tightened down the clamps and pump at oil tank. Any other suggestions?

Again, just to verify: you are getting a "low oil" alarm? Describe again exactly what kind of alarm you're hearing and what light goes on. How long does the alarm sound, how long is the light on?

How much oil is in the oil tank?

What exactly have you done on the oil supply side? It's a little unclear what you've been doing on the gasoline side vs. what youv'e been doing on the oil side of the system.

When you mention tightening clamps, what kind of clamps are in use in your system?

Re: 1996 225 Ocean Pro VRO????

Hello Again,
DaJohnson, quick synopsis: I get a flash from the led and a audible alarm every few seconds when I run over 4600 to 4800 RPM's.
I have changed everything out on the fuel side. Lines, Bulb, Filters, tightened and replaced clamps with hose clamps around vro. On the oil side I cleaned out the lines and re tightened everything down. The oil reservoir is full.
Friday I went out and had no alarm, thats a first since I bought the boat. However when I came back in I did. Let me explain: I primed both engines, no problem starting, I let them warm up for about 5 minutes while I was doing some other things. They both ran fine, I played with them up to around 5500. I shut them down for about an hour to an 1 1/2 while I was clamming. I forgot to prime both engines, and proceeded to start and warm them up for a few. then when I went under power I lost my problem engine. I went back primed it, the bulb was not full. Attempted to power up right away and it stalled. Re primed it again, did not feel full, warmed it up at about 2000 for a few and started out again, only to hear the audible and the led every few seconds over 4500 rpm's. Other then that she ran fine.
That was lengthly, any clues pop out of that story?

Thanks All!!!!:D

Disconnect the sensor wire at the fuel restrictions switch and see what happens. Sensor may be bad.

How many red lights on your guage, how are they labeled, which one is comming on when the alarm sounds? have you looked in the bottom of the oil tank to see what is lurking there, water, trash, gelled oil??

Re: 1996 225 Ocean Pro VRO????

Is the fuel restriction switch at the vro where the oil hose connects?
I have one led light for each motor. The led flashes every few seconds as does the audible alarm.
Food for thought, one day this week I went out on a very calm day and no alarm. I came back with some wind and waves, not to bad, however the alarm and light signaled every few seconds.
I haven't looked in the oil tank, thats my next stop.
Could the float be bad causing it to alarm in rough seas, but then again why would it stop when I lower the rpm's below 4500 (slower boat less rocking).
What do you think!
As always thanks for the input.

Re: 1996 225 Ocean Pro VRO????

Must be aftermarket Tach. You can locate the sensors, disconnect one at a time, run engine, until you find the one sending the signal to beep the horn. You have 2 overheat sensors, 1 no oil sensor, 1 low oil sensor, 1 fuel restriction sensor. Your guage and beeper will not tell you which one, because it is an aftermarket tach. The Evinrude/Johnson Tach for this engine has 4 lights, these will set until you solve the problem, or it goes away. The overheat will set S.L.O.W. and hold the rpms to about 2500. You said engine turns 4800, this rules out overheat, only 3 left.
