I removed the evinrude from the starflite and was wondering. If i wind up putting the Rude back on the boat after I finish the transom I was thinking of removing the VRO. My question is ,what must I do besides remove the oil line to remove the VRO. Will it hurt to just take it off or must I do something else?
let me know your thoughts
 
VRO

I replaced the origional three wire Vro on my 89 225 with the newer 4wire OMS pump. It uses alot more oil now, I was told the origional pump was between 150/1 and100/to one at idle and then around 50/1 at full throttle. The new oms is 50/1 idle and 40/1 wide open. I also replaced all of the fuel and iol lines,clamps and the oil filter witch is on the end of the pickup in the oil tank.

my concern is I've heard of the VRO's failing and frying a motor. Is what you did an upgrade to keep this from happening?
Just wondering cause I don't mind mixing the gas and I don't want to puke a motor
 
vro

Alot os vro failure stouies are really from lack of maintaince with the things I have mentioned, keeping the oil and fuel lines airtight and in good shape and changing the oil filter every few years. Yes the new pump is an upgrade, they even have an upgraded oil tank cap witch i changed. I'm confident in mine for a 6500 rpm 225 without premixing.I bought it on ebay for $275.00 us new in the box, it was a complete kit with instructions.

Good advice in the above post... mine also has the newer style vro on it.... I'd leave it on, or upgrade to the newer vro... its a good system... the shop manual outlines the vro system checks for the warning system, its really easy to check everything out (warning lights,horn,ect.).

I'll never own a 2stroke boat motor I gota premix- PIA... everyone is different, though...
 
i thought (and i could have the wrong motor here) but when omc vro's pack it in, they dump excessive oil into the engine, as opposed to mercs which don't pump oil at all (cooking the motor).

i know omc had huge problems with their oil pumps, i beleive the part supercedes something like 10 times, i would think they have figured it out by now.
 
Bad Vro's

Chris,It was on the very first ones(85) I think, the rubber diaphrams where not compatible with the alcohol that was starting to show up in the gas and they went soft. The early models where not equipped with no oil alarms either. From my researchThe newer 4 wire units are as reliable a system as any.
