kwl1763, if that flexable air tube is the softer blueish stuff you better 86 it for the good o'l fashion clear tube... I used that blueish stuff and after about 1 month it tore in half. The clear tubbing is the way to go... it gets as hard as nails the longer its in the water

Good to know, I'll do that!
I just heard from someone that funrcboats.com just now ran out of Octura propellers :lol:
I'm betting both towerhobbies.com and funrcboats.com are wondering why these plastic propellers are selling like hot cakes all of a sudden.
On a side note, I am in search of a small low RPM and high torque motor in order to build a motorized swivel mount for these MJ mods. If anyone know of a good source for these motors, please give me a holler I'm aiming for 1 to 6 RPM, around 1 pound or more of torque. Thanks

I was unfortunate enough to order dumas props the day before you posted about the octura's, and I didn't want to pay $11 shipping for the octura's when I have dumas. Now I just need the best price on some mj's.

Not so D.
If you look at the Seio impeller, it is optimized for spinning in one specific direction. Note the pitch:
I haven't figured out exactly how they do this. I have a Gorman Rupp 510, and it has a uni-directional impeller too, the fins are slanted to one direction. I think some of the high-flow, low-head Iwakis are the same way, but I'm not sure. I can't tell if it is something mechanical making them spin correctly, or something in the circuitry that does it. I know the AC Tunze models are electronically told to only spin a certain way.
Might be worth looking into. Just from looking at the pumps, I can't see anything on them that would make the impeller change directions, but it somehow always spins the right way.
Do you mean something like this?

It has possibility.

Yeah well.. I'm not sure then. I have to admit I didn't look at the SEIO impeller closely enough to even notice the slight pitch in the blades but given that I too am baffled as to how it is spinning the right way each time. Can you take more close up pictures of this impeller? Different angles maybe?
Sorry the link didn't work.It's www.usplastics.com

Heh, that's not mine, it was taken from o2manyfish's website. But I just recently got a pump for my closed loop, a Gorman Rupp, and I had it apart for cleaning, and I'm telling you - I looked that thing up and down and could not find a single thing that would make it spin the right way.
I think someone just needs to make a Stream mod out of a Seio without a stopper and report back as to whether or not it is still functioning properly. That might be a clue that it is something internal in the pump, rather than external in the impeller.
Any volunteers?

i made the mod to the seio and it doesnt start the right direction everytime. now looking at the pic of the seio impeller, look closely and you will see that it is made to spin the opposite dircetion we want it to spin. which would be why my seio would start like 99 out of 100 times backwards. doh. also i just got all my octura props today, guess what, i didnt order a single right handed prop for the seio, lol. well i did try out some props on the seio and the biggest i could get it to spin was a 1445, the 1450 and the 2045 wouldnt spin, but then again i was just holing the shaft by hand and moving it around to get it centered . i also noticed thatthe seio likes to spin the best when the magnet comes out about an 1/8". did fool aroudn with it too much, maybe this weekend. i do know that i need to find a pump for the 1460 prop that i have, that thing is a monster.
as far as the seio impeller and the gormun rupp impeller, the quite one pumps have uni directional impellers too. i think the motor must spin harder in one direction, or something like that.
anyhow i did take about 2 minutes to play with the 1200 that i have lying around. i wish it would spin the 1445 prop that i have since it is the smallest that i bought. maybe i'll have to order some right handed props to play with the seio some more but for now i am gonna look towards finding a pump for the 1460 prop.
also why is that seio prop pink when everyone that i ahve and have seen are light blue
