It could be the right one but an older model? I just compared my spare that Ecotech just sent me a few weeks ago, and it's different than the one that's currently in my tank. The new one, the propeller and the and the shaft is 1 piece. Whereas in that video and the running in the my tank is 2 separate pieces. But at least you can buy the entire assembly for $20 opposed to $75 for the whole wet-side.
