I have a '96 Johnson 50hp 2 stroke and was on the water with it today when going full speed which is about 30 mph for me. Made a turn and the motor slowed to a stop and cut off. It wouldn't even attempt to turn over for the first five minutes of me foolish around and then it started right up. Only problem now is that when I put the throttle down the boat doesn't go any faster probably 8 mph. It's running 3300 rpm but there's no speed and it is terrible. I'm really hoping I haven't done anything too serious that's going to hurt the motor or my wallet. Thanks in advance for any help.
