umm is say more like some people are unlucky or their build just isn't perfect enough.
for anyone new to the project id always advise to use the dumas 3004 and once ya really know what you are doing try the octura 1440. thing is the dumas always works , is it really that important to get 2300 gph rather than 2000 ?
simply put i think the 1440 pushes the mj to the very edge of its of it's ability. any time ya do that with anything you are bound to have some not not work. all it takes is a slightly weaker MJ or magnet or just a tiny flaw in your build that produces excess friction.

id like to note that the carbon fiber combo produces more friction than the SS rod/plastic tube until its been worn in for quite a while.
personally id never use the carbon fiber rod. The tube is nice but id use the SS rod with it instead. the carbon fiber has all those little ridges that rub on each other.

Here are my thoughts on this
1. The Octura 1440 is much more aggressively pitched than the Dumas 3004 so you might be pushing it with your MJ1200.
2. Not all MJs are built eually. Some have stronger/weaker magnets that others IME. Also depends on the age of your pump too.
3. If it can't spin without the shroud on then the prop is definitely too big for the pump. Try the Dumas 3004 or the smaller Octura 1435.

I just bought a few Dumas 3004 props, so I'm going to give that a shot.
My shroud build comes out really clean and now I'm also using a RC Plane wheel to perfect the centering of the rod. The shroud is mistake proof, but the prop is kicking my rear.
Hopefully the 3004 will work and I can finally put this built behind me and start my next adventure.

You can also just cut your prop down some.
If it spins out of the water but not in the water, that always means your prop is too big for the pump, ceteris parabis

You just do your best. I have cut a few down and I know ther werent perfectly balanced, but I never had any problem with them. I think as long as you dont make one side dramatically different, then you should be fine.

When mine clatters around I lower the MJ in the tank and it will right itself. Then just raise it back up.
