please help ! Impeller size for water pump MD7A/B

Post by archie »

Hi,

I am looking for an impeller for a CD 28 which has either a volvo
MD7A or MD7B engine. This is for the water pump. The factory part
is too expensive. Does anyone know any other source for an impeller ?

Thanks !!!!!!!

I've heard that NAPA has these.
I don't have the part number, though.
I'm sure a more knowledgable CD owner will soon come to the rescue.

Archie,

Defender and West Marine do carry this impellor. It is the smallest one they carry too. I remember that the number is a 4 digit one..2011 or something close to that. Try checking the catalog, and if you still have trouble, I will grab the catalog tonight and send you the exact number. They run around $13 each by the way. These are the Nitrile compound impellors, which can run dry for a 20 min. period if need be.

Try this site. They match impeller to engine. WM sells these in their catalogue.
