 Knocking sound, Help!
I have a 23Hp Dixie mud motor. I just rolled over 4 hours on the motor. This morning when I ran my boat I noticed when it get about idle there is a knocking noise. It only does it when the motor is trim down in the water. I've checked the the belt and it was tight any suggestions.
