EFI Drool

[Jimmstr17]

I have a SX225TXRY which translates into 2000 225HP OX 66 Saltwater Series w/ 25" shaft. Have had the boat just a couple of months. Each of the last 3 times out I have removed the engine cover and found raw (unburned) oil puddling up below the butterfly stack. I am using Yamalube and have replaced the external fuel/water separator cartridge as well as the one under the cowl. Can the injectors be "tuned up"? Synced? Is that what they need?
Thanks.

make sure both the oil tank vent and the crankcase breather tubes are attached to the airbox.
the breather goes to the lower nipple.
