    Description

    Exhaust Water Shutter Flapper for 4 Inch Y pipe used on Mercruiser. Fits into the "Y" Pipe on most V-6 & V-8 engines to help prevent water from backing into the manifold
    Replaces
    807166A3, 18-2732-9
    This does not use any pins or grommets to hold it in place because it has 2 tabs molded into the sides which snap into the holes which the above grommets used.
    If your flapper currently has round grommets that hold it in, and a 4 inch Y-Pipe, then this is the correct flapper If your current flapper is held in with square grommets, then you need 807166A1
    Does Not Fit 4.3 Engines Originally Equipped with the 1 Piece Exhaust Manifold
    Fits 1982-1996 engines with oval 4" Y-pipes with round pin holes
