Prop Spin??

 Something I just saw on Fishful Thinking and seems like a good idea, when your going down the hwy do you realize that the wind turbulence can actually cause that prop of yours to start spinning?  I've never thought of it before but at higher speeds that baby could really be doing  few miles per hour no doubt!  The problem you "might" have is the wear that's caused by that prop spin when it isn't in the water.  Granted, the unit is sealed and the bearing are being lubricated but there certainly isn't the cooling effect when that leg is submersed in water.  I honestly don't know what the wear factor is but, if it at all concerns you all you have to do is put the motor in gear and no more spin!  Pretty simple and with the price of repairs nowadays I think I just might start doing this myself!!
