I'm baaack! At least I think the PC issues are sorted out........

Anyway, The GE pump is a different animal. I did a swap last summer in my old Charger of the complete GE Pump for fresher one that had the Energizer kit and a Place Diverter on it. The old one developed a helluva shudder that I still can't explain fully even after dissassembly.
This is what they look like all apart. Note the impeller more resembles a desk fan.....

And this is what an "Energized" version looks like.

FWIW, as it is, it's a good pump for larger, heavier boats at moderate RPM. It'll never be a speed demon, and I wouldn't recommend astronomic RPM with it, as if that'd do anything for it anyway. I never GPS'd my 19' Charger before the swap, but I'd say it was a solid 45 MPH boat, downriver, with a tail wind...........After, with the energizer, we GPS'd 55 with it at Big River, and a best of 59.4 after some tuning last summer. Theres more in it with shoe/rideplate adjustments and maybe adding a droop and loader, but for a boat as heavy as that Charger is with a very mild 455, that's not too bad.
Somewhere I have pictues of removing/replacing the entire pump, but I wouldn/t recommend that, since the suction/intake is one unit epoxied to the hull ( VERY WELL, I might add). The pump can be rebuilt/upgraded without pulling it or the engine. Replacing the pump with another type, say a Berk, is a huge endeavor, while the Energizer upgrade is quite pricey. However I've seen some smoking deals if you keep watching the boards and C/L for used ones.
