Hey, I just wanted to give a short update that I have not been able to dive to check if the blades are moveable. I was using a rotating wire brush to clean up a rusty area on the boat and one of wires detached from the brush and shot into my leg...
Hehe I tried but could not find out how. Anyway the wire is out and after only two days I barely notice the would anymore. Still can't go into the water though.
