Water Distribution Housing 863631T1 for MerCruiser 350 MAG MPI 5.7L
Product Overview
Manual drain water distribution housing for Mercury MerCruiser inboard and sterndrive engines, supplied as 1 x housing. It replaces 863631T1 and 863802T2. The housing sits on the engine and gives each drain point a single manual valve, so the block and manifolds can be emptied for winterising or after a flush without pulling plugs. Fitment covers the 350 MAG MPI, 377 MAG MPI, 383 MAG Stroker and the GM 4.3L, 5.0L, 5.7L and 6.2L MPI engines listed below.
