Sunk Grizz now engine has rapping sound

Sunk my Grizz on w-end, didn’t have time to shut it off!
Drained water, changed oil couple times, no problem starting it but it has a terrible loud rapping sound. Kinda sounds like a wrist pin in 2 strokes but way louder. With a screwdriver thru spark plug hole i can’t feel any slop when rocking the crank back & forth.

Any ideas??
