Fresh Water Pump cooling system

Haro,  Webmaster
1999 Catalina 36 MKII

My tardiness in replacing the fresh water pump of the cooling system - weeping hole dripping with antifreeze - resulted in a 1/4 of a cup of antifreeze in the bilge.
I purchased a new one for about $ 400.00 that included the gasket.
Removing it was not problem. Then I had to carefully scrape off the residue gasket.
To reinstall the new gasket is recommended to be dampened then install the new pump.
I used a syringe to refill the lost antifreeze - about 10 oz.
I started the engine expecting to see high temperature, which means air in the system requiring burping. But burping was not needed and temperature stabilized at normal 162 F.
