[QUOTE="kofkorn, post: 367744, member: 7076"] I only wish that it was the prop hub. When I spin the flywheel, I can hear and feel the clunking in the bottom of the powerhead as it skips splines. It won't even turn the prop when it is out of water and turning by hand. I can spin the driveshaft easily with the prop, but that doesn't turn the flywheel. It's possible to build up the end of the shaft even further, or even maybe use some aluminum foil wrapped around the end of the shaft to thicken it a bit further instead, but I'd be concerned about the strength of that when I open the motor up. Maybe use the foil to center the shaft and the socket/hex to drive the prop... I have to pull the powerhead tonight and look at the clearances before I go much further. From what I recall, there's a good bit of empty space below the powerhead, but I don't remember exactly how much. Thanks! [/QUOTE]
