Very late and the wrong model
I ordered this replacement water pump in December and it arrived ten weeks later in March!
Not only did it take far too long to arrive but when I tried to replace my old water pump with the new one, it became obvious that it was different and did not fit my engine, even though the replacement pump has the same model number.

Technical question
Roy B. | Sep 10, 2021 Flag of English
User image of Roy B.

I have an obsolete Jabsco 6640-200 pump on my old Petter AC2W mini twin engine. The pump is in poor condition and considering change for new. I can’t find a direct equivalent but think it might be good to fit slightly larger unit as I did successfully on another boat. I am looking at the Johnson F4B-8 though the F3.5B-8 may be better but not in your list. I have found sizes of this unit but vague as to which part the size equates. Do you know where I can find a dimensioned diagram? I need to ensure there is physical space. Any other advice on this matter would be appreciated. Regards Roy
