Yes, that is an impeller for a 3 slit water pump. I purchased it years ago
from Grubb East Coast Marine. At the time his supplier had decided to
stop making impellers. So it is No Longer Available. Mr Grubb retired not
long after.
As for outside diameter, look at the vane impeller in preceding thread. notice that the vanes take a set which in effect reduces diameter. In this
case I believe “Close enough is good enough”
The STRONG stream of water flowing out to Joe B’ s Wizard WD3 indicates that as long as impeller is reasonably close to original that
the motor is happy. AND MUCH better than worn out or on their last
legs impeller. A friend had the unhappy experience with his Mark 30
impeller that shed its vanes…scored cylinders before he was
aware water pump was kaput.

For what it is worth, every original impeller I have seen was 5 blade
while replacements all seem to be 6 blade. Perhaps a patent issue.
