    Running MTU 16V2000 m91's in my 2004 65' Viking sportfish. Port motor is burning 10gl more fuel per hr than the starboard @ 1850RPM. The load is also off, Port 90%- Stb 80%. Anyone ever seen this? Any insight and help with this is appreciated.

    You need a MTU tech out ASAP with laptop. Could be a bad injector with a split nozzle, a dropped valve seat, a low cylinder, or turbo issues or a full gammit of issues. All will be very serious if left un-attended. This is provided there are no issues with the props being dinged or something like that.
