There is a very significant alternate reason to consider a EWP (electric
water pump).
Engine cooling is required. Flight critical redundant systems just make
sense for aircraft. A EWP is the lightest cheapest, fully capable back up,
that has a further advantage of being powered an alternate way from an
Engine Driven Water Pump (EDWP).
It was success as a backup system that drove the idea of EDWP replacement.

Power. We pay good money all over the place the get a few extra horses,
or a little less drag. Real world dyno test are showing up to 9Hp gains
with the EWP, with most of the gains at high RPM (where we're at).
Weight. We pay good money all over the place to loose a few ounces.
The EWP will save POUNDS.
Balance. I consider lead in my tailpost a problem.
Configuration. The EDWP just doesn't fit well in a lot of cases.
Reliability. Belts are very reliable, IFF installed properly. Very few
of us have factory jigs to verify 100% accurate installation. The EWP
makes a backup pump easy.
