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.

Check your oil.

Seems like oil may be low
