Sierra 18-5967 is a replacement alternator for Mercruiser stern drives, rated at 55 amps with a serpentine pulley. It fits 1996-1999 GM V-6 and V-8 carbureted engines in 305 and 350 cubic inch sizes, and it is load tested at 100%. Sierra has discontinued it and superseded it with 18-5967-1, so that is the number to look for going forward.
Our take
The 55 amp rating and serpentine pulley on the 18-5967 suit the 1996-1999 GM carbureted V-6 and V-8 engines it is listed for. Note that Sierra has discontinued it in favour of 18-5967-1, so that newer number is the one to track.
