The remote oil tank feed and return hoses attach to tubes at the starboard front of the lower motor coverThe 14 in(6,35 mm) line is oil feed, the 5 16 in(7,94 mm) line is oil returnOil is drawn from the tank by the crankcase pulse-driven oil pumpA hose connects the pump to the oil injectorThe injector is ECU-driven, and supplies oil pulses at approxi mately 40 PSI (276 kPa) to the oil distribution manifoldInjector operation and oil output are variable as determined by the ECU, depending upon throttle position and engine RPMWhen the ECU completes ground connection, the oil injector operatesIt ceases when the ECU ground is brokenThe ECU can detect an injector open circuit, and in such cases will store service code, turn on the System Check "NO OIL" light, and initiate S.L.OWThe oil distribution manifold controls oil supply to the crankcase via six equal length hosesThe hoses connect to metered orifices that discharge oil immediately behind each reed valveAnother hose supplies small amount of oilthrough check valve, to the fuel hose immediately before the lift pumpEach distribution manifold outlet is controlled by check valve that prevents oil drainback when the injector is inactiveApproximately 6-20 PSI (41-138 kPa) pressure is maintained throughout the system by regulator located in the hose returning to the boat's oil tankTo ensure powerhead longevity, the ECU provides special oiling modesDuring break-in, oil supply below 2000 RPM is at normal programmed ratio; above 2000 RPM, oil supply is doubled, up to maximum 50ratio, for the first five hours of operation After break-in, the oil supply mode is the normal programmed ratio, regardless of RPM INote When
