Okay I have a 03 Baja outlaw 5.0 mpi mercruiser. Here what is going on with the boat always starts right up gets going and as I’m driving the boat rpms jump and yes new iac valve replaced and it’s working. Now when I take a turn it really spits and sputters has new cap, rotor, plugs, fuel filter. The only thing that I can think of is fuel pump?! Today I ran some k100 in it to see if it was possible water in my tank and ran it pretty good down the lake and still same issue. Next on the list is fuel pressure test. Any help ideas is much appreciated
