VRO delete 150 oceanpro

[oyster gro]

I just bought a 1999 150 oceanpro and I want to run premix. what is the proper way of disableing the oil half of the pump. Thanks

Re: VRO delete 150 oceanpro

Why?

You can purchase a kit that has is very easy to bolt on. I will. Get the link and send it.

thanks. So you don't seal the hose and unplug the wires like some say ?

Why?

I don't mind mixing fuel but I do mind worrying about a pump that I know nothing about. just wondered if there was a right way or a wrong way to do it. thanks

Re: VRO delete 150 oceanpro

There is a sticky on the procedure.

BTW - that OMS pump is a very reliable system, with warnings for low oil and no oil. You have the option to test the sensors and if they work fine, run the motor with the oil injection. I recommend carrying enough oil on board to premix should you have a failure, which is pretty rare.

Re: VRO delete 150 oceanpro

Actually will run into more problems by pre-mixing the system. The system was designed for Varable Ratio Oiling and by pre-mixing you will defeat the purpose and will have problems with coking of the cylinders and fouling sparkplugs. There is probably more systems you don't understand under the hood of your car but you don't see people trying to disconnect them. Failure of the oiling system is very rare being its tied to the fuel pump and one can't fail without the other failing. You only hear those that don't understand how the system works saying they want to disconnect it.

Re: VRO delete 150 oceanpro

I just checked the book and you cannot delete the VRO pump being its built into the fuel bracket assembly between the six carbs. Its not the old style that hung on the side. Trying to delete it would require a lot of replumbing of the fuel system and modifying.

the factory OMS for the 1997 V4 115 hp ocean runner fits the V6 models into the 2000's . Heck it even fits the 250 hp models

(0438400 FUEL PUMP ASSY) thus the dual regular fuel pumps they use on the commercial V4 60 degree loopers should fit as well!!!

food for thought,thanks for taking the time to explain it. I've seen some vids.on youtube of just pluging the hose and unplugging some wires. Just wanted to see if that was proper or not.

I picked up a 1995 115 hp Ocean runner 5 years ago...It had the oil disconnected....I have since used it with premix....still have120 PSI compression per cylinder........the harness from the oil tank is unplugged, and the oil line is plugged right at the fuel pump.....don't know what other magic could possibly have been performed!!!!!!!!!! I use my motor a lot in the dead of winter...when I use MUCH more oil In the gas thn nomal......I have no idea how I could get a VRO, or OMS pump to add more oil in the winter!!!!!

Re: VRO delete 150 oceanpro

Go to the top secret file at the beginning of this forum and it tells how to disable the oil side of the VRO and use the VRO for a fuel pump only mixing your fuel 50:1. That VRO makes a good fuel pump only and you can get repair kits if it fails. Good choice. I've hated those VROs since they first came out in 1984 as there were to many problems.

Re: VRO delete 150 oceanpro

Capt Ken, that VRO or now OMS has been mixing the fuel at 50:1 since around 1996. No more VRO.

Didn't make any sense. Why mix more oil in the winter where your already running rich and loading up from the low combustion chamber temps.

Re: VRO delete 150 oceanpro

Your combustion chamber temps should be the same year around if the motor is up to spec.

Re: VRO delete 150 oceanpro

not being a smart a** (intentionally, anyway), but how the heck can you know what mix is pumped into the engine in any of these systems? That is, unless you premix, how do you know? I know there is an oil tank, and you can tell if the level goes down and how much -- maybe the remaining level tells you what the running mix has been, if you know the amt of gas burned?

RICH?????????? how do you figure? the air is MUCH denser in the winter and there is more oxygen in it ...thus leaning out the fuel mixture.....NOT making it rich.

but I have always been told to add more oil in the winter....there is more dimensional changes from the bitter cold cast aluminum to the warmed up cast aluminum.......the bore might actually be a little tighter at 5 degrees that when its 80 degrees outside ...AT STARTUP!!!

Re: VRO delete 150 oceanpro

How do you know how much fuel is going through the injectors in your vehicle? The VRO is a measuring device. One plunger with two pumps. One is for fuel while the other is for oil and it mixes internally. One can't move without the other and if the oil pressure drops the alarm sounds.

 

[oldboat1]

Re: VRO delete 150 oceanpro

yeah, capt ken. That's the point of my question -- have to trust the device to tell you if the device is doing it's job. You get faulty operation with a faulty auto injector. You get a destroyed 2-cycle motor with a faulty oil mix.

Re: VRO delete 150 oceanpro

And what if the wire to the alarm is broken or fell off so it doesn't sound ??
