I set mine up with a DIY wave maker I made with an Arduino, I posted it earlier. The original K1400s that I had "EVO" had issues. The bearing would slip and the rubber stopper would come loose. I glued the bearing and it was better, not good but better. I bought another 1400 Evolution and it has a new bearing design and is considerable quieter, a simple click instead of the thud. Right now mine are on a 15second interval, I got a good wave going with 5sec but to much thudding and clicking.

I am not sure if this is correct but I think I read some where that someone took some small diameter tube and put a small piece on the exposed shaft between the impeller and the front stopper. Stopped the clunk of the impeller jumping when start up.

That would make sense. You would have to get the length right as the bumper is there so that when the magnet charges it sends the impeller forward to hit the bumper then engage. This is how they have engineered it so that it will start in the right direction.

Was looking at mine last nite and on evos there is a little nub on the front plastic cage that has something to do with it (Mine broke off from what I can assume is the prop hitting it over and over on the wave cycle)
Because it hasn't been touched since it was in there. The good is the sound is gone on that side.... The bad is that it now sometimes starts in reverse..... Going to ask about a replacement. Cheers... TJ

Let me know if the new bushings quiet it down at all. What interval time is everyone running these evo's on? Also, what are you guys doing for placement with these? I like them on the top middle of each side facing eachother down the length of the tank( how most people have the mp40's positioned) However, its an eye sore not having them on the back wall...
