Brand New Marine Circulating Water Pump for 1998 and newer model GM V6 4.3L and GM 5.0L / 5.7L engines which have NO BYPASS, with plastic timing covers as used by Mercruiser and Volvo Penta. (Includes gaskets)

NOTE: Be sure to match the outlet holes and gasket shape to your model. If your model is 1998 or newer V6 or 5.0L, 5.7L V8 without a bypass, SOME of these models used this pump. If your pump outlet has 2 bolts and a water bypass hole instead of just 2 bolts (like this one), take a look at MPR2232MN.
