I believe it was 88 or 89 that OMC started the newer VRO2 that monitored the pulses. Like SKOOLS said though, early ones had no monitoring. Newer DFI engines use all electric pumps to meter the oiling now. ALL of the newer MERCS(including the regular EFI's) and the ETECS and later FICHTS have an electric pump and that goes directly into a distribution manifold that puts the oil staright to the bearings. It's going to be int5eresting to see how many powerheads fail once these electrical systems get to be 10+ years old and those pumps begin failing.
