Why is my MJ1200 with SureFlow mod doing this?

fkshiu: I'm not sure what you mean about the flat side in front? Do you mean the flatter edge of each petal should be leading the spin, not following?

The guy I bought it off is sending me the black propeller, so hopefully that one will work better.

Go back to page 1 of this thread and look at Mike31154's pictures. The top picture shows the correction propellor orientation.

If you put the black one in a Maxijet 900 it should definitely work better although you won't get quite as much flow.

I will check the prop orientation tomorrow when the lights are on. I would rather have less flow than all this noise. I just need to get by for a couple months or so. Good thing I have LPS, not SPS!

Taggin along, my MJ mod actually spins the cover off sometimes..

Fkshiu, the orientation of the propeller is backwards now that I have flipped it around. The flat side is following, not leading. It won't work with the flat side leading. So that would further point to the fact that the propeller is actually spinning the "wrong" way right?

Ha, ha, so my assumption was incorrect in that it may have been flipped around, so much for my brilliance! It 'should' work more efficiently if you return it to the original orientation, but that seemed to give you more grief than the current config...

In any case, either way the propeller is flipped, provided it spins counter clockwise (and the tabs take care of that), it will push water out the front, as intended. The flat side leading is supposedly the correct orientation, but who knows... it's now once again a mystery.

Aha, photos, fantastic. The difference in leading & trailing portions of that prop is nowhere near as radical as the one I have. As per your assumption, I don't think any previous owner has flipped it around, so you should probably return it to the original config. Hopefully it will still work.

If there are any hobby shops in your area, model boats, planes etc. check them out, they may stock small plastic propellers you can try in the place of the one you have... while you're waiting for the black one to arrive in the mail. Hopefully you don't end up breaking it in an effort to get it off again... good luck and we're anxiously awaiting the results..
