Hello All? New here. I was going across the lake today going about 45mph. I heard a clunk. Slowed down didn't hear anything no alarms sounded fine at idle. Took off again clunk again this time the motor sounded different. Took cover off sounded fine. I ran it back to dock at idle. Trimmed up it sounds different. Still sounds same at idle. No alarms at all. I did bump the gas a couple times and it wanted to go but doesnt sound right. Anybody have any ideas where to start? Thank you.
