hi, If a propeller is spun and I can actually turn it by hand around the hub although it is pretty hard to do, putting the boat in forward it churns up water but doesn't move at all, in reverse it wants to go, doesn't seem to spin at all...at idle in both gears. Although it is idling way to high in my opinion and I haven't figured out how to turn it down yet. I ordered a manual off ebay and still waiting after a week and a half. <br /><br />Rich
