I have tried to find out the year of our Evinrude 225 outboard with no luck. I have a partner, and we are new to boats. We feel we purchased a good boat (open 22.5 ft center console) and a good engine. The compression test was ok for all cylinders and the engine has been operating without problems for several months now. Engine looks in good shape and well maintained. However, we want to replace the VRO as it seems to be causing excessive consumption of oil. I want to be sure of year before looking for the replacement VRO computer.<br />Model: E225TXARK<br />Serial: G03523881<br /><br />Thanks in advance. I have registered today on iboats, and this is my first posting. I have been reading through many postings, and it is amazing how help is offered in such a devoted manner.

I believe the Model #E225TXARK<br /> would be 1994 - ER, Instead of AR. Check again and let us know!

It's 50 -50 Kesh. Half that have it love it. The other half takes it off and pre-mixes.<br /><br />c/6<br /><br />Hooty

Re: Evinrude 225 year identification

Hey Hooty, I couldnt understand that...maybe because of my english... you mean I should premix oil when fueling ? I always ensure the oil tank is full before a trip. I am afraid that premixing will cause excesive oil quantity reaching the engine.... Some folks have told me that it is better to eliminate the VRO system and keep premixing all the time... However, I like to have the oil tank operating correctly so I avoid having to take care of the litters of fuel I put when refueling and then mixing the oil in the right quantity.

Re: Evinrude 225 year identification

It's a 1994. The "A" means alternate color and replaces the "E". AR and ER are both 1994.<br /><br />If you are using too much oil, it's possible the pump (which is a 50:1 pump - not variable) is doing it's job. If there is a fuel restriction, not enough to sound the alarm or alarm not working, the pump will supply more oil than needed. <br /><br />Good luck!

Re: Evinrude 225 year identification

Kesh,<br /><br />I believe what Hooty is trying to say what you eluded to in the 2nd part of your post. He is saying some people remove the VRO portion of the system by pluging off the oil lines, and just premxing the fuel.<br /><br />From my experience, I have seen slightly different results; about 75% premix, and 24% replace the VRO. Out of the 25% that replace it, we see about 50% that come back within a year or so, and need to replace it again. This is why I believe the 75% opt to save themselves the $225+ for the pump the first time, and just premix.<br /><br />Again, these are just my experiences, and doesn't mean that this is what other people see.

Re: Evinrude 225 year identification

Kesh,In order to make a determination as to whether the VRO pump requires changing or just servicing of the system one would need to verify what your description of too much oil use is.Mark a line on VRO tank and use a given volume of fuel .Then calculate the ratio used.Also, does motor seem to smoke excessively?This would be a side effect of excessive oil in mix.I would think that if there was enough fuel restriction to show a measurable excess of oil use that there would be some performance symptoms .

Re: Evinrude 225 year identification

First of all, thanks to all you for taking time to make suggestions. I apprecciate your comments because it seems that there is a lot of experience concentrated here. I also have to say that I am familiar with engines and mechanics (I was an aviation mechanic many years ago and also have worked on automobile engines) so feel free to use technical terms if needed. The problem is that this is my first outboard motor. I am reading like crazy to get familiar with boat engines and systems, but I have lots of doubts.<br /><br />OK. Now I will try to be specific:<br /><br />1) I will make a determination of the actual oil/fuel consumption proportion, as suggested by OB. Our concern is actually based on the excessive smoke, which "looks" more than normal (when compared to other boats).<br /><br />2) Thanks for the VRO replacing or not comments. My first approach is to replace it, as we don't want to premix ...you can read "lazy" between lines here.. :D However, with your last replies now I have new doubts:<br /><br />2.1) I was believing that VRO is for variable oiling, but Dhad says the pump is not variable?...I am confused here :confused: <br /><br />2.2) There are no symptoms of poor performance because of fuel restriction. However, a question arised in my mind here: If I decide to premix, will the oil in the fuel contaminate the water separator filter and reduce its useful life ????<br /><br />2.3) Is the VRO a computer, and the oil pump is a separated piece, or is it a pump+computer in one piece? ...I have to admit that I haven't seen it, but the other day the mechanic pointed to a small electronics module on the side of the motor and told me "this is the VRO computer".<br /><br />Definitely I will buy the manuals for the engine, to understand those details :D <br /><br />Finally, Rick and Dhad THANKS FOR THE ENGINE YEAR IDENTIFICATION !!! :)

Re: Evinrude 225 year identification

Kesh, the Vro is a air motor driven pump via crankcase pulses.The fuel and oil pump are part of the same unit.They are of piston style.The year model pump you have has also failed on some units by either developing a fracture in housing between the oil and fuel half or failing seal between same.The fuel and oil pump pistons are driven by a common rod from air motor.Frequently the first symptom of this fracture or seal failure will show up as excessive smoking ,particularly at start-up.The vro pump assy has sensors within it that detect low fuel flow and low oil pressure. The sensors are wired through your alarm control box in motor compartment.The unit can be removed while leaving the high temp alarms in use if you so choose.The VRO pumps fuel half works just fine as conventional fuel pump at 50:1 mix.Premix fuel will not render your water separator inoperable.

Hey OB ! what can I say? Your answer is just perfect for me, Thanks ! I think we are going to replace the VRO unit with a new one.
