The water pump is the orginal on my 78 Excella and works great. Only problem is the bottom plate is cracked and leaks.
The pump is the PAR 36800. I only need the bottom plate. It's the plate on the bottom of the pump, black, attached by 9 screws, and it measures 4" x 4 5/8". The plate has a # on it - C5623.
Just wanted to let everyone know - Jabsco makes the PAR replacement water pumps, which cost about $230. Anyway, I called a Jabsco Service Center to see if I could get the bottom plate for my water pump (which was made in '77). And they had it! So, before you replace your PAR/Jabsco water pump with a lesser model, call one of the Jabsco Service Centers.
