I used a Sierra 18-3073 impeller in mine. I can’t remember if anything had to
be modified on it or not, nor can I tell you if it pumped water, as the motor
was just too low on compression to start in the test tank.
Here’s all my notes, but I can’t swear everything is 100% accurate!
The photo shows the impeller, which I assume is the new Sierra one.
