    I have a 75 9.9 Evinrude long shaft. I brought it out yesterday and started it up with no problems, started on 4th pull. Shut it off with kill switch.
    I ran in it in a clean trash can ful of water, was water sputering out of pee hole.
    Came back approx 4 hrs later to re-start, will not start. Replaced fuel, checked fule lines for blockage, pulled off carb-clean as a whistle, checked spark - lower cylinder only - but should at least fire.
    I am at a loss right now - dont want to spend big bucks at repair shop on old motor.
    Any suggestions?

    Could be a bad coil if both cylinders are not firing or it could be the plug wire.

    I was wondering too about the kill switch, if the kill switch is stuck it shouldn't spark. Right?? Pushing the kill switch was the last thing I did to it when it was running. Maybe Ill try to bypass the kill switch to see what happens.

    This motor is on my 22' sailboat. I changed the name of the boat without the tradition. It could be that the boat is mad at me. Was planning this engine to serve on my jonboat, has a 20" transom and the longshaft is what it needs.

    Check the wires going to the kill switch. I have seen a lot of them that the insolation on the wires going to the kill switch have peeled off and shorted.
    That motor has a coil for each cylinder. I would check the points first if it's not firing. The points should be set at .020 . Look for cracks in the insolation on the coils. You have to remove the flywheel to check points and coils.

    Yep, my girlfriend warned me about changing the name without the "ceremony".

    I went out and the best I can figure is that I do have a fouled plug, as I switch the plugs around to see if it will spark when I pull the rope.
    Will be checking the kill switch too. Question remains - will it spark if the kill switch is engaged?

    no it shouldnt if the switch is engaged (making contact)
    if your getting a spark make sure your fuel line is pumping fuel
    pull cowl off and raise the motor and pump your bulb up good and tight and see if fuel comes out of the carb throat.

    I have pumped the bulb and it is getting fuel to the carb.
    Will put new plugs in on Tuesday.

    i have a little smallengine spark tester that is better than useing a screwdriver to ck your spark but it should be a nice strong blue spark not a weak orange or red . coil could be at fault if spark is weak check both cylinders
    test tool should be fairly inexpensive .
    good luck !!!!!!!

    Get you a spark tester best little money you will spend. Also look under the flywheel there should be a black wire running from under it to the kill switch and unplug it. It should spark. If you had one fould plug it would have started on the other one.

    What type of plugs did you get and gap them at 35 that should help and also when was the last time the carb was rebuilt and cleaned real good.

    Had champions in it, Oreilleys only had NGK,s. Would rather have champions, will keep an eye out for them.
    Sure does run alot smoother banging on booth cylinders!!

    You need champions in it. Those coils weren't designed to fire hot enough to run it good on NGK plugs. It may seem to but believe me its not
    Find you some QL77JC4 plugs to go in that motor and gap them at 35

    I will go find the champion plugs, maybe use the NGK's as spares to keep on the boat.
    When I took the carb off, took the bowl off it, it was clean as a whistle - gaskets are new looking. Thinking that this carb had a rebuild in the last year. The motor overall is very clean, i think someone has taken good care of it.
    This forum is great!!
