    I have a 2000 Mercury 40hp ELPTO that I want to remove the oil injection system from. Can someone give me the procedure for doing so.
    Any help would be greatly appreciated.
    Thanks,
    Keven

    Keven, I'm no expert, but if you are talking about doing away with the oil injection and mixing your oil. I think all you need to do is remove the oil line coming from the oil reservoir and mix your gas 50:1. This will make for a rougher idle though on most engines, but should be fine on top end.

    I removed the oil injection from my 95 40 hp mercury years ago. I think
    Vern is right you run your gas line straight by-passing where the oil
    enters the gas line. You also have to do away with the electrical circuit
    that alarms when low on oil. I do not remember if this is a closed or
    open circuit. When disconnected if it alarms you will have to trace
    your color coded wires to the terminal board an close the circuit with
    a jumper. If it does not alarm just disconnect the wires going to the
    oil injection at the terminal board and pull them out. Mine was just
    two wires.

    Looks like you guys have him about covered,

    Kurlee to answer your question you don't have to remove the pump because that is your fuel pump also.
