To really test that theory youd have to install a new VRO pump and see how Sals engine ran when its VRO system was working as it was designed.
The acronym VRO is for Variable Ratio Oiling and the design goal was to reduce the oilfuel ratio to around 1100 at idle. Your Johnson outboard model number can usually be found on the nameplate located on the motor or the mounting bracket. The nameplate should contain a model number and a serial number.

OMC introduced an oilgasoline mixing system for their outboard motors in c1984 and called this feature a Variable-Ratio Oiling system or VRO. Over the years some engine failures caused by lack of proper lubrication have been mistakenly attributed to defective VRO components.
Every Mercury outboard has a serial number label located on the transom bracket area of the engine. The latest serial number labels display a 2-digit number in a box at the lower right portion of the label.

The first V4 was rated at 50 horsepower and the basic engine design was manufactured from 1958-1968 reaching a pinnacle of 85 horsepower in 1968. This engine is most commonly identified by its single 2-barrel downdraft carburetor. In 1964 a second V4 with minor changes was introduced.
I had a 1992 Johnson 90 hp with the VRO. It had the original pump on it when I traded it off in 2013 I never had a problem. From what I was told the first model VRO was the one that was defective which were the late 80s models.
