try 1 1/2" Cu pipe with a bell reducer to 3/4 FNPT right at the pump inlet

I'm gonna throw a stupid question at that...
Volenti (?) mentionned (at OCAU) that measuring the pump head is different wether the pump is submerged or not: something to do with the water having to speed up into the pump inlet (when submerged).
My Q: is there such a thing as too big an inlet?
