1998 Johnson 200 check engine light

[Striper80]

So I was able to get down to the boat and check out a few things, but I wasn't able to run it due to it being too late at night. I found a t fitting leaking right before what I'm guessing is the sensor for the check engine light. The sensor for the check engine light is the one that the wires fell off, but reattaching them didn't cause the light to go out.
I'm going try and find some type of non conductive epoxy or rubber to refil the cavity of the sensor and fix the leak and do some further testing this weekend. I still need to see why I had a "no oil alarm" momentarily. The tank was low but I never got a low oil alarm. One thing at a time and I'll run it premixed for a little while on a separate tank.
The sensor is the white thing below the vro.
