Hi, and thanks for the replies. I must say I feel a bit silly since I have now tested with more water in the tank, above the physical location of the pump casing, and it is now pumping the water fine. the M8B seems to need more water than the MFS6 4 stroke that I am more used to. Thanks again...
- We've inherited an engine (M8B) which was apparently serviced and had a new water pump impeller installed a couple of years ago. It hasn't been run since.
- Routine service just completed and tank test run - all great except there's no water exiting the check port.
- All pump components, incl...
