150 ficht makes slight squeaking noise at idle

[a4ceone]

I went thru all the threads and havent seen any similar posts. I recently bought a boat with a 1998 150 ficht, it has had all the updates done by dealer. My question is, there is a squeaking noise that can be heard at idle... the engine runs fine but wanted to see if anyone else has had this.

thanks

It turned out to be the keyway for the fly wheel. Mine was a 2004 200 hp
