    I have a 1997 Johnson 130.
    As you will be able so see in the video, when I throttle it up (normally for the first time) It will have a missing or as if it is not firing on all cylinders, It is carbureted. If I shut it down and then restart (sometimes takes more than one try) it will run normally. Any thoughts on what the issue could be? After the first time often I get through the rest of the day and it is fine?

    I had the same trouble
    I had a small hole in a fuel line before the fuel filter
    I replaced all lines myself and never had the trouble again
    NAPA said it was from “corn fuel” eating the lines

    Check the plugs. Look for one that ts dirtier or cleaner then the rest. Then after you find that out. With all plugs out of the motor and help from a friend. A few beers should cover. One at a time check for spark. If all have good spark its in the carb

    I beleive you have an intermittent ignition problem, most likely an ignition coil. It warms up and then starts working. This was my exact problem on a merc 115.

    When it is missing shut of the key switch and put into neutral at the same time. Then look for the wettest spark plug. Should be the corresponding ignition coil with a problem.
