    I’m betting the hole was 3/16 originally and is just dirty or burred over preventing a 3/16 pin from sliding in. Only Elmer over in Cedarburg would have drilled a hole 0.005" smaller than a common size.

    It looks like you reacted properly when the bottom came up and touched your motor. I’ve heard a persons natural reaction is to reach out to push the motor away from them when it tries to jump in the boat. Apparently there is more than one senior citizen walking around with a crippled or mangled hand from coming in contact with a spinning flywheel this way many years ago.

    Retiredoz advised that Olson’s # 11 is the only one that uses the decimal spec instead of fractional for diameter (.181 x 1-1/2 on the package) and fits a bunch of K motors. This would be even better than my original which is 1-1/4" long.

    When the motor jumped up at that speed it was pretty violent – all big rocks on the bottom. I was cruising the shoreline because the water was very choppy that day for the video. The motor spun around to reverse position which probably helped to keep the prop off of the rocks while the boat glided further into shore (the impact turned the boat directly to shore) and the tree branches that nearly whacked me. This put the kill button pointing up so I went for it. The only problem I had was not holding the button long enough. At that speed, the motor re-started once or twice! 😆
