With engine running with I'm hearing a knocking sound which seems to be coming from the lower unit? I can hear it out of the water with flusher on. While in the water, I don't hear when in neutral, but if I put in gear I can hear it. Doesn't seem to be coming from the motor. Oil pressure and oil level is ok. Gear oil level is good, clear and clean. Sound is becoming more consistent, was inconsistent initially. Everything is operating properly, otherwise. Any suggestions are really appreciated, as I'm hoping to avoid an on the water breakdown. Thanks!
