    That is a reluctor sensor and you need to put it back on the camshaft bolt asap!!!

    looks like a low oil presure sender to me, but I could be wrong. If you pulled it off right at the oil filter mounting base thats what it is. You can run without it if your not concerned about your oil presure. They were to used to kill the ignition if the oil went below set psi. I think they have 3 wire terminals though.

    So I can honestly say... I have no idea.

    its a pressure switch/sender. depending on if that only has 2 terminals or 3 will likely determine whether it is used to control something directly. (such as ignition or fuel as futs said) or if its just used to signal, in the case of a dummy light or gauge. could be used for oil or possibly fuel. however 2 terminals can still control something.

    also could be a knock sensor/transducer...which is still basically the same thing.

    where did it come from? was it in water, oil or fuel port?

    That is a oil pressure switch. Their are other places you could put it if you can get that plug out.

    There are two reasons to have an oil pressure switch, one for a warning alarm and on a fuel injected boat a safety switch for the fuel pump. Does your boat have a mechanical or electric fuel pump?

    Either way it is best to find an oil port to put that in.

    Looks like a Hobbs switch to me,if it had wires running to it put it back in, looks like its a two wire Normally Open switch. when your engine gets oil pressure it will activate something.
    if you have an electric fuel pump it could be controlling a fuel pump relay.

    you can add a tee to the oil port located directly above the oil filter pad, normally your oil pressure sender is located there.
