Mercury 40 has occasional high pitch squeel

  1. My 2003 Mercury 40 ELPTO 2 cycle 3 cylinder seems to have a high pitch squeel once in a while. It's not real loud, but definitely noticable. I put the motor in neutral yesterday and it still squeeled. It seems to occur mostly in the first 1/2 hour of operation, but I do recall it happening briefly a few other times during a long day and then it stops. Any ideas? Otherwise, it runs like a champ. I must note that I took a good chunk of the skeg off a few years ago, never had lower until problems or water, but not sure if this is related. Any help would be appreciated. Thanks.
     
  2. If if spelled squeal right, would I get any helpful ideas?

  5. Guess I'll take closer look under the cover again and look for rubbing. I'm not interested in a breakdown so I'll investigate til found and fixed.
