I have a 1990 Evinrude 70 HP with the VRO system. It has worked fine until
this summer. The warning horn comes on. The motor is not overheating and
seems to be getting oil. When it first started I added oil to the gas and
checked the water coming out of the telltale. It is running cool and using
oil out of the tank (oil tank is 3/4 full). Anyone have a circuit diagram
for this system ? Any ideas of how to trouble shoot it ? Some people have
suggested removing the whole VRO system and just mixing oil with the gas.
Any suggestions or ideas welcome.
Bob.
