Hi everyone, i heard a loud noise from the engine when running at low speed and suddenly i lost thrust. I used to be able to go as fast as 40 mph and now it's only 28-29 mph. first i thought i hit something because the water was shalow. The prop is SS and in good shape, same as the feet of the motor. Need some help diagnosting my problem. Out of the water guy.
