My MaxProp is an older 3-bladed model—perhaps the “Classic”—which requires assembling a lot of loose parts on the shaft, as Minne describes. You would have to deal with this if you wanted to change the pitch. PYI does not recommend doing this in the water! (We had to reassemble our MaxProp in the water once and it took my son 90 minutes on SCUBA in shallow water that allowed him to plant his feet on the bottom. It was either that or get towed to a marina for a haul-out.)

However, IIRC, the newer MaxProps allow for an easier adjustment in the water. I can’t tell for sure, but it looks like the prop in the video is a newer model that has a much simpler adjustment process that still needs a diver, but does not require a haul-out. That said, there may be an assembly problem with the prop in the video that would not allow for an easy, in-water adjustment of forward pitch, but it wasn’t apparent from the video. What is obvious was that the yard screwed up and should have noticed this problem before launch.
