gotcha, when I read "cut exactly halfway through the 1.5" PVC pipe" I thought you meant cut half way through the whole pipe.

Here is my first ROUGH CUT
Here is my first ROUGH CUT
Great diffused flow.
Ripple picture.
I found that reusing the original impeller housing made the job go quick and gave an automatic center device for making the cross brace.
Another view
I will make a couple more, with a better finish. I am also going to try a 4 bladed prop. The one on my boat spins easier and pushes more water.
Anybody have a link to a 4 blade prop (1.25")

to my knowledge there is no such prop. the diameter is just too small to fit 4 blades effectively. real boats of course are larger, ussually have 3 or 4, and newer boats now use counter rotation. which would be fantastic but not realistic for us of course.
btw Im not sure about the whole miter saw, but mine did not work like yours. infact I damn near lost a few fingers when it kept yanking the pipe and shattering it. seems unsafe to me.
I went with a table saw, since pipe is cheap I took about a foot long section, and set the fence to 6". then I set the blade height to leave maybe .5 mm of pipe. and rotated it against the miter guide and fence. for me this was SUPER easy to do, and got a flawless cut through it.
just an alternative if others chop saws dont fit quite as nicely as the OP's did. well... and alterative if you happen to have a table saw... could also use a circular saw with the fence dropped down real low and a friend holding and rotating the tube...
personally though the pipe diameter was too big still, so i took off about .5 mm of the outside of the lip, (using the same method as the tunnel but blade height even lower). then used a dremel to knock off a little bit of the hooks that hold it on. as is I found the hooks were bend out and I was afraid theyd crack off. these 2 mods seemed to make it fit much better.

This is why I said to use a fine toothed saw blade. The regular large toothed blade will indeed kick the pipe back if you're not careful. Also the direction of the saw teeth and how you installed the blade will affect this too.
For the slots, I used a masonary grinding blade on the miter saw.
Still though anything involving power saws (even a table saw) must be used with caution.

Gserg2 did you use the mj 900 or 1200 with the new props?
Right... But the coupling is what 3 to 4 inches in length at most? Try holding on to that while cutting the slots and see how easy that will be 
I cut the slots in my pipe first THEN cut down to size to what I want the whole thing to be. Safer and easier to control especially when dealing with power saws.
