Can anyone identity this sound?

[colby]

I'm thinking about buying this boat and motor. Started it up and I hear this. Sounds like it's coming from around the flywheel. Kinda sounds like a rod knock, but when I put a rod to my head and the engine case I didn't hear it.

I hear a tinny sounding knock. Don't know what it is.

wow i got something that sounds similar but ive been unable to find the culprit ive got a separate thread goin about it cus i originally thought it was a rod bearing but im pretty sure its not it. my next theory is maybe a bad gear in the gear box. i have a video of mine making a similar noise in this thread https://www.marineengine.com/boat-forum/threads/57-lark-rod-bearing-availability.476086/ you might check the flywheel and make sure its tight and not able to move at all also
