I have a
Yanmar 3GM30 with a
Jabsco water pump">raw
water pump. When replacing the impeller I saw that one was a K10x7 and the other spare was a K11x7. Can anyone tell me the difference between these 2 impellers. Which is correct for my
pump. I have already had to reinstall the
pump 4 times trying to fix
leaks only to find that all my spare water
seals were the wrong size, hence the
leaks.
