Since we bought our boat last June I have been fighting a serpentine belt squeal I changed belts, idler pulleys and just about every remedy I found on line it would go away for sometimes a week then return. Finally I found an old recall notice from mercruiser for the alternator, power steering and oil filter bracket also included a recall on the sea water pump bracket. If you take a straight edge and check the pulley alignment to the crank pulley mine were off about 1/8" on the sea water pump about 1/4" on the alternator pulley. This recall covers a lot of engines built from the mid 90's to 2002 it expired in 2004 for mercruiser to pay for repairs my Sea Ray dealer did pay for the brackets if I did the labor.
Yesterday I finally put the new sea water pump and bracket on (will rebuild the old one for a spare) then replaced the alternator bracket that bracket was one real pain you need to remove half the front port side of the engine. I started at 9:00 am finished at about 3:00 pm launched the boat after running on muffs looking for any leaks before launching out for a test ride squeal is finally gone. The pulleys now are all in line.
