    I'm having some issues with my 25hp Johnson on my gheenoe Classic.

    Any help? I have changed the plugs, power pack, and changed gas tanks. Thanks for the help!

    Have you taken it out to run it at high speed? Did it rev up, or just die out and turn off?

    Sounds like one cylinder is missing to me.

    After listening to the vid, I'd be checking for ignition problems.
    Sounds like one cylinder is getting zero spark.
    Bad plug wire, loose or corroded wire to the power pack.
