Outboard Knocks when decelerating?
I bought a newer 19 center console hull and put a 1996 Mercury 115hp offshore edition motor on it and it runs great. On the bay it can run around 42mph. There are about 345hrs on the engine. When decelerating from a run above 20+ mph there is a knocking noise but only at the higher speeds, kinda like the knocking sound of when putting it into forward are reverse. I heard it was called the Deceleration Knock that these engines are known for but just wanted more opinions.
there is a you tube video that I watched. The were explaining what sounded like the same problem. There is gears in your lower unit on a high rev the centrifugal force brings to the center and when you decelerate it starts to wobble. Hope this helps
