Hose clamp and reducer is the answer. All you need is a 2" length of hose that
will fit over the pump outlet and adapters to duplicate the outlet O.D. and a
pair of hose clamps.

Pool pumps typically need to be properly primed before they will pump. They are
not self priming. If this hose you are connecting is on the pickup side, you
will probably need to fill it with water (run water from a hose through it
backwards?) before you turn on the pump. You will also need to keep the pickup
beneath the water surface until it is all pumped out, or air will get sucked in
and pumping may stop.

"Adapter" what kind of adapter, that is what I am trying to figure
out? Don't you need some kind of reducer? What does this adapter
look like? Thanks

Gee, that's a nice recap of what OP wrote... :)
I never had a pool so don't know what they use routinely; I'd presume
there is some standard hose for that portion. If it is for 1-1/4" hose
to go over the outside rather than for a fitting to be inserted inside,
as suggested, a short section of that would be needed unless 1-1/4"
plastic coupling will also work.
I'd try the plastic coupling route first -- if so, get a slip/glue to
female adapter, then reducing bushings to 3/4" NPT and then the NPT to
hose thread adapter.
If that solid 1-1/4" won't work, use the short 1-1/4 hose w/ a barb
insert adapter and repeat the exercise from there.

It looks like a short length of plastic pipe the same OD as the pump fitting,
and the appropriate fitting to adapt to the hose fittin you want. I can't tell
you exactly, because I don't know your hardware store. Personally, I'd use PVC
pipe fittings, probably 2" of 1" white PVC pipe(which, I believe, is 1 1/4" OD),
a coupling, a 3/4" inside threaded reducer, and a 3/4" pipe thread to male hose
fitting adapter, which might be brass. You'd also need PVC cement to glue the
PVC parts and maybe teflon tape or pipe dope. Asking for help at you hardware
store will get you the real answer. They may well have a simpler answer. It just
depends on what they stock.

I suggest checking http://www.fernco.com/
They have all sorts of flexible fittings. You might find what you need
there.

From the shape w/ the groove, I'd wonder if there isn't a mating
disconnect coupling designed for the pump.
Here's a generic for the idea...

My thoughs exactly. As for pool pumps typically not being self
priming, he better have a talk with mine. It's a garden variety
Pentair and it self primes. I think a quick look around would suggest
that most are self-priming for obvious reasons.
As for the fitting to make up what the OP needs, I'd start with a
piece of hose or tubing that fits the pump. Then a PVC barb fitting
that fits the hose, appropriate reducers to take it down to a sill
cock, which will connect to the garden hose. Should be able to find
all that at any home center. Sill cock is the only common thing I
think every store would have that connects to garden hose.

CAUTION
DO NOT run the pump dry. Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal, and may cause property damage or personal injury.
(copied right from the Pentair Owner's Manual)
Even the Pentair Dynamo series -- the ONLY aboveground Pentair pool pump that even hints it can "self-prime" -- expects the basket to be flooded with no air leaks on the incoming line, and contains this warning:
NOTICE: Never run the pump dry. Running
dry may damage the seals and pump housing.
This could allow water leakage and flooding.
(reference instructions on pages 9 & 10 of the manual http://www.pentairpool.com/pdfs/354554.F%20Dynamo.pdf )
In other words, only a fool is going to run any of these pumps dry (unless he likes replacing the bearing seal regularly).
NOW, back to the original question.

What you really want is a pool cover pump. I'm going to order one of these:
https://www.poolsupplies.com/product/the-cover-pump-350-gph-w-auto-onoff-switch
I was already looking because my reliable old Water Ace R6S submersible pump I've used for the past decade has finally reached the point where it has to be partially disassembled and manual "tweaked" to get it to rotate. Hey. It was used when I got so who knows how long it has been working.
ANYHOW, I'm going with this even though it doesn't have the same volume because it is automatic.
Use the right tool for the job and you can't go wrong.
And no I don't work for any of these companies or their friends, I'm just a guy with a 15-year-old pool / pump arrangement that still works great and I like keeping that way.

> Yeah. Not a great idea (the pump that is). As we've established, a "pool" pump has to already be full of water with no air leaks on the incoming line to get a flow going (and prevent bearing seal damage).
get going. There is no check valve on the suction line, the pool
eqpt is almost always higher than the water level in the pool.
Hence, when first putting the pump into service, there is no water
in it. You can put some in at the strainer basket, but as fast
as you put it in, it runs right back out again because the pool
water is at a lower level. The most you can do is have it wet,
a little water in there via a garden hose, but it's mostly air and
when it starts you can see it takes maybe 30 secs to draw water
in. That doesn't harm the pump. Letting it run totally dry
for 15 mins with no water, now that's a different story.
In reality, they aren't expected to just start sucking up water because the impeller (the part that pushes the water along) is NOT sealed ergo it expects to have something solid (like water) to push against. Air won't do. That is why pool pumps are installed _below_ the water line of the pool which keeps them flooded at all times (assuming the water level is at least an inch above the bottom of the skimmer inlet).

water level, you'd have to have the eqpt pad in a pit in most installations,
where the land is flat. All the ones I see around here are installed
with the eqpt higher than the pool water level.

amount of water from a pool cover doesn't make sense to me either.
