I used the search and found other post but i didnot want to do this myself without getting a straight answer for my engine. i have an 1996 evinrude 90 engine that it seems the vro is going out. Should i disconnect the vro and premix??? please help. seems the VRO is going to cost some money getting it fixed. thanks in advanced for any help....

'96 ?

Take it off, mix your own!

In a word. "YES" Do'nt even try to run the engine with a shoddy VRO, unless you want to rebuild the engine.

Any detailed info for removing the VRO?????

(VRO Pump Conversion To Straight Fuel Pump)You can convert the VRO pump into a straight fuel pump, eliminating the oil tank and VRO pump warning system, but retain the overheat warning setup by doing the following:1 - Cut and plug the oil line at the engine so that the oil side of the VRO pump will not draw air into its system. Trace the wires from the back of the VRO to its rubber plug (electrical plug) and disconnect it.2 - Trace the two wires from the oil tank to the engine, disconnect those two wires, then remove them and the oil tank.3 - Mix the 50/1 oil in the proper amount with whatever quanity fuel you have. Disconnect the fuel line at the engine. Pump the fuel primer bulb until fuel exits that hose with the tint of whatever oil you used. Reconnect the fuel hose.That's it. If you want to test the heat warning system to ease your mind, have the key in the on position, then ground out the tan heat sensor wire that you'll find protruding from the cylinder head. The warning horn should sound off.---------------Also, the following may be of interest to you.(Warning Horn Wire Routing)The three wire plastic warning horn that came into existence with the VRO era must have the wires connected in one manner only. To have them reversed results in having the horn omit erratic false warnings. Notice that the horn has two plug on type terminals and one black wire that is incorporated within the horn. The "TAN" (sensor) wire must be connected to the terminal closest to that black wire..... with the "PURPLE" (12v) wire connected to the terminal fartherest away from that black wire.----------------And for those that may be interested in the various warnings.(VRO Horn Warnings) 1 - A steady constant beep = Overheating - The V/6 engines, possibly some others, have a fuel restriction warning which is also a steady constant beep.2 - A beep every 20 seconds = oil level has dropped to 1/4 tank.3 - A beep every other second = VRO failure, air leak in oil line, oil restriction, (anything that would result in a lack of oil being supplied to the engine).
