i have a 33 ft fishing boat, that has 2 8.2 l detroits, when i full throttle the port engine it will come up to 2200 rpm and the turbos are spinning, the engine will bogg down and go to 1000 rpm and below. changed out the raycoors 30m and checked all fuel lines.i am not sure if it is a fuel or airside problem. air intakes are clear and pulling, fuel seems to be there,but i do not know if the lift pump is making good pressure to the fuel rail.i really do not know what to look at next, any feed back would be greatly appreciated--thaks patrick
