Description
  • The water shutters are designed to meet or exceed OEM specifications.
  • Replaces Part #: 807166A3, 18-2732-9
  • Designed for MerCruisers engines 1982-1996, there are some 1996 and 1997 models that apply. Fits the oval 4" Y-pipes with round pin holes. If you have two rectangular holes for the grommets you will need the A1 water shutter. If your Y-pipe changes size a few inches bellow the shutter you have a one piece manifold V6 Y-pipe and need shutter A2.
  • This is a replacement for the original flat oval plate with a round pin that is offset in the Y-pipe
