My 1994 4 Winns Horizon 210 with 5.8EFI, OMC Cobra outdrive, has been burning up alternator belts since I bought it a few years back. During acceleration, the belt squeals(it is slipping on the alternator pulley)and this slipping eventually burns and breaks the belt. The alternator checks fine at an alternator shop. I changed the alternator pulley with no luck. I put in a new alternator and it worked for about a year, but the problem has just recently started again. It only seems to do this in gear under acceleration and not just revving the engine in nuetral.
