Kelly, I was a johnson/ evinrude mechanic in the 90's. The only problems with these units were the ficht fuel injection systems.
If its a carburated model, I would give it two thumbs up.
Most people mistake the VRO unit for being "oil injected". VRO stands for variable ratio oiling. I have never seen one of these units fail in such a way that it causes an inadequate supply of oil. When they fail (which is not too often) they tend to over oil. How they work is they actually mix the fuel/ oil in a mixing chamber before it goes into the carb., using a series of springs and diaphragms, coupled with crankcase pulses and vacuum to meter it.
These are not my 2 cents, they are facts.
