    I had that happen on my 81 Evinrude 50hp. While on muffs running in my driveway. Idled it up slightly and it took off! Pulled spark plugs quickly and it kept going. Kill switch did nothing. Finially choked it and it died. Luckily no damage as she’s still running well to this day.

    Did you ever open it up and determine the cause?

    I did not. It still runs fine to this day. I just don’t ever rev it on the muffs. Learned my lesson. In the lake you can rev it and it’s fine. Must be the lack of back pressure while on the muffs.
