Some details to note:
Offered is our replacement for the 44446A2 Mercruiser Heat Exchanger for the GM Big Block engine. This was designed for the early model Mercruisers. This offer includes the heat exchanger, end caps with gaskets, and zinc.
This product was used in virtually all Mercruiser Big Block Engines as a rear mount heat exchanger for a full system (cooling both block and manifolds with glycol/antifreeze) from about 1981 through 1997.
This is a rear-mount heat exchanger which means it mounts over the transmission.
5-inch cooling tank diameter and 21 inches overall length
