Experience with VRO - Moderated Discussion Areas Experience with VRO AuthorTopic: Experience with VROpcrussell50posted 01:10 PM ET (US) I've read, (several times), the excellent reference article right here on CWW about Evinrudes VRO system.Jim, how did you find life with VRO, when you had your old 225? I have a 1993 Johnson 115 with the VRO removed summarily by the previous owner. BUT he gave me the nearly new VRO pump with the deal. I'm thinking of installing and using it. Not becuse I mind premixing though, but simply as another lesson and experience in my journey as a boat keeper.-Petercontenderposted 01:31 PM ET (US) Peter, I purchased my Evinrude 140 Engine brand new in 1985 from a dealer that is no longer in service. I loaded the engine in a crate in the back of my pickup and carried it home. After reading all of the instructions (well some of them anyway) per the factory papers it was not required to connect the VRO and the VRO on the engine was plugged from the factory as well.

They also stated that the VRO did not need to be connected and would not void the warranty. I was mounting the engine on my 1975 16'7' whaler and space was a priority on the hull, so I went for the mixing of my gas and oil.
Evinrude e-tec. Evinrude Outboard Motors is a company that builds a major brand of outboard motors for boats. Founded by Ole Evinrude in Milwaukee, Wisconsin in 1907, it was formerly owned by the.
The other reason I was a little worried about the system, was that I did not like the design of the oil pump (Evinrude VRO has to suck the oil were as an Yamaha pushes the oil through the hose) I felt that if the oil hose bent or collapse inside it would/could kill my engine. So I felt a lot safer with the oil gas mixing. Plus I just liked the idea of KISS without the extra tank, conections, hoses to go bad. Since 1985 I have replace the inside(Evinrude has a kit for this) of the VRO twice once was becuse I was redoing the boat and it did not need the fix just wanted to do it, second time I felt that the diaphram may have a hole in it/gettin old so I replaced it. The only down side I can see is it may burn a little more oil and smoke a little more on the start up.
However the engine has NEVER given me a problem and runs just fine.Tohsgibposted 02:38 PM ET (US) I still have the resevoir & hose that you wanted last year.pcrussell50posted 02:41 PM ET (US) Good! Consider it sold. I thought maybe someone else beat me to the punch a few months back. Email forthcoming.-Peterjimhposted 05:45 PM ET (US) The original equipment oil mixing or VRO pump on my 1992 Evinrude E225TXENR outboard engine was operating just fine when I owned the engine.
I was keeping an eye on the pump because during the last season of my use of the engine, which (I think) was 2009, the engine was in its seventeenth year of operation. Because of the prevalence of ethanol fuels, I was a bit concerned about the pump. However, when I sold the engine in 2009, the VRO pump was still working normally. I told the buyer that although the pump worked normally, I was anticipating replacing it if I would have retained the engine, just as a preventative maintenance procedure. I have since learned that the new owner replaced the pump in 2012, which would mean the twentieth year of operation. I think some sign of incipient problems with the pump prompted its replacement.Given the gasoline fuel we have today with ethanol, I think it is prudent to replace 20-year-old VRO pumps.
The new OMS pump is not cheap-I think its cost is over $400-but it would be a good investment in maintaining an older engine.If you get a new pump you will be getting an OMS pump. The oil ratio will be different from the original VRO pump. The new pumps should be more tolerant of alchohol-gasoline blended fuels than the original ones.Moroccoposted 06:36 PM ET (US) I second Jim, although everyone (including the mechanic who maintained the engines from new in 1987) told me to take the VRO stuff off my Johnson 150 XTs and just 'mix in the tank.'
