Hardscape cutting and saw question

I have been a longtime lurker here and have a couple questions.
First, I am currently working on a overlay on a pool deck. There are some boxes along the deck, not sure what they are called, that spray water into the pool. My question is how do I cut the hole for these boxes? The boxes are 3"x3". The block thickness is 2". I used a 4.5" angle grinder with a masonry blade on it, cut the square off the top of the paver and thru the bottum too. Doing it this way theres still alot of material holding the cut and it pretty much breaks the block every time i hit it. Should I also be drilling this out with hammer drill and cleaning out the corners with some sort of masonry bit in a die grinder?

Second question....Not too long ago we got a mk 5.5 hp masonry saw. The pump dont work so decided to sell it. A friend of mine is going to buy it when we are done with this job. I want a new edco, prob the 6.5 hp. My question is this...the saw I am running now, dry cutting, seems to be very weak on power. I have used it before on regular size pavers and it worked well. But these bigger slabs are giving it a fit, while the new shihl ts700 rips through them like a champ. Is this size saw not enough for this type of work or is the one I'm running now worn out? (air filter is clean) A saleman has recommended the 9.5 hp edco but its a fair bit more money. Is this smaller saw what you guys are cutting the larger slabs with? Or do you just use the handheld? Thanks for any advice!

I'd be talking with a pool guy to see if there is anyway to move those up to the surface - having a 2" deep 3"x3" hole right next to a pool doesn't seem like a great idea to me.

If its not possible, just over cut on the bottom side of the block. Cut the top and then cut the bottom - no one sees that side.

The boxes, although it doesn't look it in the pic, are allready high enough to be flush with the top of the paver. I tried to cut exactly how you said and every time I would hit the middle of the square to knock it out the slab would break. I've ordered a masonry bit for a die grinder hopefully it will be able to clean it up

I may get called totally crazy but it seems that you will have to have radius corners , not sharp corners, kind of like in woodworking because cracks will happen or develop

If I had no other choice I might try coring a hole in the stone and then just using a bit of tinted mortar to dress the open areas left inside the circular cut

As far as the saw not cutting well, the blade will make a huge difference. We have a better blade in the hand held and it cuts quicker than our stationary saw.
