    1996 Evinrude 15HP Stuttering/Surging approaching & at WOT

    Powerpack is the correct part, but the problem was indeed at the powerpack. Took me a bit to get back to this after being away, but it came down to a loose/corroded ground connection. There was an old rusty star washer stuck to the head there (from before I replaced the powerpack I'm guessing)...

    1996 Evinrude 15HP Stuttering/Surging approaching & at WOT

    Thank you all. I did buy a new fuel line and connector today, and although the fit seems much tighter, they didn't make a difference either. In the second video, you're right, I didn't have it wide open. WOT it was still bogging and surging, at 75% it was kind of stuttering/popping so I was...

    1996 Evinrude 15HP Stuttering/Surging approaching & at WOT

    Hi all, Wondering if anyone might have any advice for me. I have a 15HP Evinrude (E15REDS) that started stumbling at WOT last time out a few days ago. I replaced the spark plugs but no improvement. Tonight it was sputtering approaching WOT and then sort of surging when I did get there. Fuel is...
