We hit something today and bent the crud out of one of the blades on my prop, i don't have a puller yet so havent removed it but looking behind the prop the key is off allignment is this normal or perhaps it spun when we hit something. If the prop key spun on the shaft what needs to be replaced or what other issues should i look for? Everthing looks OK other than the prop and possibly this key.prop 2.jpgprop 1.jpgprop 3.jpg

Thats a bummer, never seen a prop key damaged like that with my boat, but have had to pull my prop and get it repaired a couple times, really helps I have a spare from the first time it was damaged. The guys at Nettle Props always do a great job fixing my props, looks like you will probably need a new key also. The prop puller I bought from them comes in handy when trying to remove, just remember to not crank the crap out of the puller to get the prop to release, crank it down a bit and hit the end of the drive shaft with a hammer to get it to release.

Getting it off is going to suck however. A puller will probably not get it off. You can try heating it. Use a torch and heat the straight shot between the blades from front to back. Pay attention to the cutlass bearing and be careful not to get it too hot. Once you get it to about 600F, beat the backside (on the meaty part of the blades) with a rubber mallet.
If this doesn't work (and it may not) I would cut off the blade nearest the keyway. Then cut the prop like this guy did in this picture.
Instead of cutting all of the way to the shaft cut into the keyway so you don't damage the shaft.
It sucks, but it's not as hard as it looks.

Wow! That had to be quite a strike to do that to the key. I haven't seen that one either but I doubt a puller is going to get it off now.My Mom said I'm not allowed to get wet!

This is what happens when you begin to get comfortable with the wife driving the boat as i wakeboard.
How do i replace the key? how is it attached to the shaft? Let's say i can get it off without cutting the prop is the blade repairable? if i am able to hold the shaft in place can i somewhat knock the prop back in allign with the key?2008 22SSV Worlds

You will not get the prop off with a puller. Once you spin a key, the prop is now on the shaft with an exponentially higher amount of friction holding it on. The key sandwhiches itself between the prop and shaft making the fit so tight that you will bend or break a puller way before the prop thinks about coming off.
You will never be able to prevent the shaft from spinning in order to try to reverse the rotation, and even if you could, you would mangle the prop and possibly bend the shaft if you try to spin it back.
Heat the $h!# out of it, and try it, but be prepared to cut it or have someone else cut it.
The prop is a loss.
P.S. Do not get nimbral shavings in your eyes.
EDIT: The more I look at it, the more I would go straight to cutting.

You might be able to save the prop (assuming they can repair the keyway-- don't know about this but a call to Nettles would certainly answer it). You will have to unbolt the shaft coupling and remove it and then slide the shaft out. Take it to a machine shop with the prop on where they can heat it and remove it.My Mom said I'm not allowed to get wet!

I was surprised how bad it looked as we just kept going and spent the day boarding, and didn't come in until dark. Didn't really get a good look at it until I got home.

My key is in NO way close to the damage of World's damage, but still upsets me as this was the second outing with this prop.
Sent by the random thoughts from the voices in my head...
- Is this prop fixable?
- Who do I contact to fix it?
- Do you guys carry a second prop (and puller) on trips to the lake?

I still claim i have never bent a prop and been driving a boat for 20+years since my wife bent this one!! she doesnt like me very much right now. It is absolutely able to be fixed, mine is being repaired and will have it back this weekend. You can probably find someone local but check up and make sure they are reputable. If not send it to Nettles in Austin, TX.2008 22SSV Worlds

Have to take the rudder off to get that shaft out with the prop attached. Where did this happen at? We saw a boat in the LSJ yesterday that looked just like yours but when we got closer we saw it was someone else
