i recently acquired a "new to me" 1972 johnson 50 HP. this is one of the electric shifts. I bought it from a local dealer here who had taken it in on trade a while back. Sold it to me as-is, however he had looked it over, said the compression was good, pressure tested, and i paid a little extra to have the carbs cleaned and rebuilt.
I have had the boat out a few times, and it works/worked great. However a couple days ago i ran the motor into the ground/mud at low speed. this resulted in the motor shutting off, while there i was able to get the motor started very briefly, it didnt sound like it was running particularly great, and the moment i attempted to put into gear it would shut off. Since then i've had it running in my backyard on muffs, seems ok, shifted it into and out of gear a couple times, seems to work fine. and i started it up in a barrel, i will say it seemed rough in the barrel.
Today i brought it out to the lake and had the motor in the water and it wouldn't start, it sounded like it wanted to. i tilted it up until the back of the prop was out of the water, it did start, and i lowered it back into the water where it ran very roughly for maybe 30 seconds or so, before shutting off again.
I'm not all that familiar with how to work on these, but i dont mind trying. is there anything obvious i should be looking at or checking?
