Cummins qsb raw water pump change

In this photo series how to change the pump. The new pump is SMX and trading was easy to do, for about about 2 hours and a few common tools.


Link SMX raw water pumps
http://www.sbmar.com/product/smx-qsb-seawater-pump/

The first three images from the pump to detect a leak, the pump looked good to see easily, leaking under the pump slowly, I never noticed the bilge water.


some of the pictures upside down, sorry!
