BX23 water pump questions

[yank50]

I've had an experience with a waterpump that I replaced and the impeller was plastic and the pump casing was metal. Under load the impeller slipped on the spline. At normal running loads it didn't slip and the temperatures were normal. I would never buy a water pump with a plastic impeller again.

Well, it's back together. Shop made a pretty radiator out of mine! Stat opens fine, 20 + temperature drop across radiator.
Cannot really see water flowing through tiny cap port, but w/ and w/o stat temp drops.
Mower running (no grass) traveling was straight up.
Gonna' have to test it on the field, observe for hose collapse (couldn't find spring that thin). They did create quite a U shape (extra 90s) that looks like it would love to fold up.

THX guys.
