It chirps all the time now when i put in gear, I did put a new impeller in this spring, no noise coming from there. @Bill Gladding , it is not causing grief but it is not normal for my boat. Is there anything I could do or replace? Should I take it in for repair? Where is the strut bushing? Can I check shaft alignment or I need a mechanic? By the way, I have not hit anything in a long long time.
