Johnson 9.9 Model #10RL76H. I put muffs on the motor low water pressure. Wife was doing wash, almost no water flow. Motor got extremely HOT!!!! I did not realize. Let motor cool down, motor still turns when rope is pulled, checked compression both cylinders 1 at 65 other at 70 , This motor does not have a tell tale, you can not see streaming water. Did I destroy motor?? Can it be repaired How? What should I do?? How do I no water pump is working?
