DIY MaxiJet Stream (Pic Intense)
- Thread starter BullDZR
- Start date
Here's a great example of a propellor that could be flipped around and mounted without spacers or washers between it and the crossbar to give it a self righting blade direction.
It will also make the most of the design of the blade by using the pitch of the blade to move more water.
Im not critiqing... just bored at work and was thinking about this mod. Mine is working great!!! Thanks for the groundwork BullDZR

If anyone has any updates on how theirs is holding up and how long it has/had been running for that would be helpful.
Will the carbon fiber rod have too much flex... and cause the same problem they had a long time ago with the plastic ones - a shaking back and forth causing the magnet to hit and various other excessive wear/noise?

I am setting up a 30 long (36"x"12"x16") and I have a question about how much flow is too much using this mod....
Would I be better getting 2 MaxiJet 600's and making this mod to them and putting them at each end of the tank on a wavemaker.... Or would a single MJ 1200 with the mod make sense? My gut tells me the MJ 1200 on constantly would probably be too much in this size tank.
Any ideas? Thanks!

Not having done the mod, I'd still reccomend the two on a wave maker, though you likely could get away with one if the flow is as good as the videos show.
The 600 might be ok but a little under powered to drive the prop without having to cut it down to a mere nub. 2 of them in the tank might be unsightly in a 36 in tank unless you put them towards the back and blow them against the front. Be aware that not only do they create a fair amount of forward thrust, they also have a nice return current. On a 36" you should be able to create a good current field with the swcd and 2 outlets per side, provided you can provide at least 900 gph at the head.

Such a great mod! I love this, when I get around to it im doing it
But for now heres a bump.
But for now heres a bump.
Ive got boats coming out my wazoo; and a used power head I bought for 10$. so I figured, alright; lets give it a go.
I cant tell you what kind of power head it is. or how many GPH it was. because I dont know. it appeared to be standard in every way though.
I pulled the impellor off. and was left with the magnet and plastic "shaft for the impellor, then a pole went up through the magnet and the shaft.
what I did was bore out the pole shaft on the inside so it would fit the driveshaft from the boat I canibalized. I bored it down about an inch(to the top of the magnet section). then I cut off the inner shaft the whole thing was riding on by that amount.(I wanted to drill out the drive shaft so it was a shaft inside of a shaft inside of a shaft. but I broke the only drill of the correct diameter.)
so now that Ive made absolutely zero sense. the propellor is on the shaft the same way it was on the boat. E ring, and the shaft is notched for a hex fitting that the propellor sits onto.
that is put into the magnet shaft with epoxy.
its all lines up; and hopefully will spin like a champ.

the epoxy sucked; need stronger stuff; and it needs something to stabilize the shaft higher up; right now; the impellor stabilizes it since it rests on the circle; so it cant tilt. but without that; the magnet isnt stable. using my fingers to stabilize it(friction) and no solid connection between the magnet and propeller. it was still getting pretty nice motion; despite the propellor turning at about 1/20th of the speed it normally turns at.
Id assume it is; alot of other parts of the boat are rusted and nasty; except the drive shaft; its perfect. so it must be something that works.
Ill try that;
the way it is; there is not much room on top of the shaft since the notch and ering spot are set into it; cant just slide the propellor down.
have to figure something out.

I wouldn't chance it. It could be Aluminum which won't rust but will corrode in saltwater.
Do what I did and use a 0.098" OD carbon fiber rod like blue7 suggested, it is nearly a perfect fit and will not corrode under saltwater. You can get these rods at your local hobby shop.

Does any one have a parts list available?
I've read all eleven pages - I've seen references but no actual list(including specific mfs and part #'s).

BullDZR was kind enough to add a parts list on the very first page of this thread you should revisit it 
Here's my specific list:
-1 maxijet 400 (on hand)
-1 1.25" Adapter SCH4 (Home Depot)
-1 1.5" PVC Test Cap (Home Depot)
-1 bag of 0.098" OD carbon fiber rods (Local Hobby Shop)
-1 1/4"-1 1/2" diameter plastic propeller by Dumas (towerhobby.com)

LOL - by the time I got to eleven I forgot what one said. My bad - sorry.
Do you know if this parts list includes the parts required to make the prop spins in the right direction - I know that topic wasn't addressed in his first mod.
