    Twin 225 johnson's, fuel pressure help

    Would anyone know the fuel pump pressure setting (holley elect fuel pump) for omc 225 v6 ?
    I just installed inline fuel pres gauges, right now I'm reading 6-7 psi at idle.
    Thank you,
    B

    Yes.....i actually read that post last night, it was good info.
    I gathered 4 to 6 psi is a good place to be.
    Shop manual states, if you have vro, 3-4.5psi
    I'm having a problem with starboard motor running rich.....i went thru all carbs, new plugs, new coils, reeds are new. The only thing left is timing.
    I imagine running the fuel pressure at 6-7psi might be part of the problem.. possibly blowing past needles.
