I got a 1978 Johnson 25 horse and I could really use some info from u guys. A while back i took the lower unit off and when i put it back on i missed the hole that the water pump hose connects to the motor. So im riding down the river and all of a sudden the motor shuts off. I turn around and theres smoke coming off the motor. Well stupid me instead of paddling back i just decided to crank it up and splash water on the motor till i got back. So i got back to the boat ramp and everything seemed ok. After i got home and took the lower unit off again i aligned the hose where it was supposed to be. I took it out a few days later and cranked it up like normal and started down the river again, then it just cut off. I went home and i believe i changed the spark plugs to get it running again. So i took it out yet again and the same thing happened. After it happened both times i couldnt get it started again. The motor was prolly not running for about five minutes both times before it cut off. And it didnt sputter or ne thing it just cut off and that was it. So im just trying to figure out whats wrong with this thing and if it can be fixed. Any info you fellas got will be very helpful, thanks.
