    Hey guys! I've been away for awhile working on my new boat and truck. Im almost finished with my boat and I started on the motor. Well I cleaned the carb and tried to fire it up, it turned over great, good compression but wouldnt crank. So i started going over everything and discovered i had no spark. I pulled the flywheel and cleaned up everything. Still nothing so I'm am stuck, i dont want to just start replacing everything until i find the problem so if i could narrow it down with yalls help i would greatly appriciate it.

    Check kill switch first, fuse second, start in gear lockout third.
    Then get the OEM shop manual, a volt/ohm meter and follow the instructions.

    I checked the kill switch and everything is fine there. Where is the fuse located at?

    How do I check the coil? How fast do you think that 40 will push a 14ft fiberglass center console? It weighs about 600-800lbs

    Get the Suzuki OEM shop manual, a volt/ohm meter and follow the instructions.
    That's the best answer you are going to get, especially if you plan on keeping that antique.
    40 hp pushing 1200 lbs of load (boat, engine, gear, passengers, fuel) will go fast enough
    to pound your kidneys to a pulp running in a chop.

    :cool:

    My 25 yammie had a cylinder with no spark after checking everything I could think of I started stretching the wires and it turned out one of the connectors was bad. I hope your fix is as easy

    That's why I recommend a volt/ohm meter. Works great for checking circuit continuity.
    Also checks the resistance in a wire, alerting you to hidden corrosion before it becomes a major problem.

    I started messing with the motor again today and i checked the fuse and it was fine. so i tried to turn it over again and checked spark... Nothing... so i pulled the ignition coil to check for a part number or something and the only thing on it was " mitsubishi electric 6510" i tried googling it and nothing so i dont even know how much to expect the repair to be. I would like to have a newer 40 but money is a major factor. If anyone wants to trade my suzuki a 1999 mercury 25 long shaft and maybe a little cash for a newer 40hp id be the happiest person in the world and i might even name the boat after you. haha

    You already checked so it doesn't matter, but if the fuse was bad it wouldn't turn over, not turn over and no spark.

    Disconnect the main wiring harness plug and use a remote starter, to see if the key switch is bad, Wait is this a remote or tiller?

    Does this motor have 1 coil or 2?

    You now have a choice to make.
    Take it to a mechanic, or learn how to fix it yourself.
    Either way it'll cost money, the question is: How much?

    Nope, you spend money on the proper tools (volt/ohm meter)
    and get the Suzuki factory shop manual for your specific outboard.
    In it you'll find complete instructions, pictures, step by step
    walking you through the entire process. You can't do the job right
    without the proper information at your fingertips.

    Not Seloc, not Chilton, not Clymers....get the Suzuki factory manual!

    or you can try looking in here...
