Hello my name is ***** ***** am I speaking with? Neither of those numbers come up or cross reference. Are there any other numbers on the pump that you can find?
Customer: replied 2 years ago.
There are no other numbers, I have pictures I can forward to an email. Will that help?
Expert:  Jason replied 2 years ago.
Not really, there are probably 5 thousand different pumps that Jabsco makes... They are all cataloged by number. I'll opt out of this one, if another one of the guys thinks they can help they will jump in. Good luck!

The place I would look is Lewis marine supply, Jerrys marine Service, Land N Sea or Cummins Marine all can be found on google. I can try to find one on Monday. ais the pulley and belt good ? The belt needs to come from Cummins the pulley may be obsolete.

I have a may have a line on a supplier. I'LL check for sure . what does the belt look like is it a flat cog or a v type?
Customer: replied 2 years ago.
Flat cog
Expert:  Diesel Boat Doc replied 2 years ago.
The company is in Miami Florida Diesel Pro Power Phone #(###) ###-####they ship world wide. I have dealt with them in the past and know the owner. You may need to change the pulley if you have the flat belt you just need to put it in the same place as on the old pump. The older engines used a v belt. if you have the flat cog belt just make it tight enough not to slip or you can break the core strands and the belt will fail the belt should have a 1/2 inch play more or less.
Good Luck
