They were available from 87-89. so the newest are 20 years old! I'd imagine the usual problems will apply, corrosion being the most likely. They came with either Mercruiser or Gill style manifolds and risers, the merc ones were a problem. Parts are readily available, as they are only Chevy motors, but some of the drive parts are pretty pricy!
