Prop frozen on

Does anyone have any ideas how to remove a frozen prop on my lower unit?

Re: Prop frozen on

i just removed mine that was frozen on.<br />First i sprayed it down with a very good penitrating oil such as LPS name brand, and let it set over night, i then used a few blocks of 2X4 under the back of the prop as close to the hub as possible, so that the prop can not go backwards. I then installed the prop nut to where it was flush with the end of the prop shaft, and struck the nut with a dead blow hammer. It worked great for me, but then again i did not care of i messed anything up since the lower unit is shot, and you would know it came off with no problem. If i had needed the lower unit i am sure it would have caused damaged, Murphy's law in action i guess lol. You could also try heating up the hub NOT the shaft, with a mapp Gas torch or cutting torch, just do not over heat, then after heating it up, try using a hammer place a block of wood on the back side of your prop blade close to your hub and hit the block of wood. Good luck.

Re: Prop frozen on

hello<br /> DO NOT beat,hammer or whack da prop shaft. do the maint next time. this time you can try a prop puller. they usually dont work. you can heat the prop with oxy/acetylene and melt the hub then cut the splined inner hub with a side grinder or you can cut the prop in two then cut the hub with a side grinder. if your concerned with overheating the case then tilt the wotor up and fill the exhaust cavity with water.<br /> good luck and keep posting

Yeah, as Rodbolt said, if you plan on keeping a good lower unit good, don't beat on it. If your case, didn't matter!! I've heated up some Slick 50 in a container(not too hot) and poured that on the shaft area sparingly and it worked. I don't know if it was the combination of heat and oil or what, but it worked when using a puller.

Re: Prop frozen on

Props are cheap. If the above methods don't work with a minimum of banging and smashing, just cut it off. I had one that was being stubborn so I put a cutting blade in my Dremel tool and sliced it right down the hub. Pealed the prop blades off, then sliced down through the length of the inner hub. Took about a half hour, but I didn't damage anything but the prop, and it was fairly battered as it was.<br /> Now, if you're talking about a $400 high-perf stainless wheel, then you're likely going to want to be a little more patient with the other methods before resorting to cutting it off. The one I cut was for a small aluminum prop...<br />- Scott
