water pump upgrade.. 73 Rude 40hp

[393Clevor]

So put a new impeller in it.. the wear plate was good, the cover had a nice soft rubber seal that feeds the motor tube.. no heavy wear marks inside.. looked good.. the tube looked good at the pump end of things. no gaskets anywhere there wasn't any when I started and there isn't any now.. it gets hot at idle even with the water level way up over the top of the pump.. as soon as you give it some it pumps good water out the exhaust but at idle it slows way way down..

I see there is an upgrade available, but this pump looked awesome, I don't see why it wouldn't pump ok.. maybe I got a leak upstream somewhere..
