I have a 2000 130 Johnson that started knocking today on the water. I first thought it was the lower engine (which may be) as I had had this happen to this the motor before and had to get it replaced. What is different this time is it knocks the entire time except in reverse. Even when the engine is off and I spend the prop foward, I hear the knocking. Does this sounds like something with the lower engine or are there bearings or something similar in the prop or shat that could go wrong. By the way, it just started knocking, as I do not recall hitting anything.
