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.Attachment 18233Attachment 18232Attachment 18234
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.
Good luck
You are ok. The brass key is much softer than the stainless shaft.Quote:

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.
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?
The key is not attached at all. It just rides in the keyway and is held in place by a tight fit since the prop bore is tapered, and the keyway in the shaft has a grade on the forward end.Quote:

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.
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

Lake Somerville, it is now 8' low we were out there 3 weeks ago and it was 5' low couldnt believe how much it has dropped in such a short time. Stay away this is fair warning! it is bad all over the lake.Quote:

That must have been it. You live in Spring right? It's probably the same distance to the T as it is to Somerville or not much further I would think. ;-)

Yes Spring, It is about 10 miles further to go to somerville. We will go there when we have a big group, there is a great spot where folks can drive cars right to the beach, but it's too dangerous now.Quote:

Pray for some rain. This is what sucks about the end of the summer here in Texas...we start running out of water!

I'll start shipping barrels!!! Take our rain! PLEASE!!!!!
It's rained every day just about for a solid 2 weeks. Maybe one day here or there with a very prolonged period of no rain, but that doesn't last that long. Boating season has been chopped in half due to all the rain for us. No point in going out and getting my boat wet! :P
Yea, you can have ours too. It's been ridiculous. Raining again now.
It's OFF!!! with no obvious damage. After yesterday wasn't sure it was going to happen when the puller cut 2 bolts in half, so got some grade 8 bolts today and was only putting moderate pressure on the puller about ready to apply the torch and boom shoots off. The key was sheared in half, one half in the prop and the other half in the shaft.
Over on CorrectCraft fan. com, there is a very good write up on proper propeller installation. Installed correctly, a prop shouldn't need the key. It is there as a back up. Anyway, do a search and it may give you a good idea on how to install the new prop correctly.
I am old, real old and have NEVER hit a prop on anything...until last weekend at Lake Oroville, where the water is wayyyyyy down due to our lack of rain this season. Saturday morning the launch ramp was real crowded with a couple of people that didn't seem to see the line at the ramp and just left their boats tied up blocking the narrow channel at the ramp. We load our boat and as we are another D!*$ Wad pulls in and dumps their boat in before we can get out of there. I should have just waited (20/20 hindsight!) but I tried to maneuver out of the way and below is the result of my ACME 1617.Quote:

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.
- 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.
Anyone know what a prop repair would cost? Of course I realize that it depends on how bad it is, but as a general idea???Quote:

My first prop in need of repair looked like that, easily fixed. My second prop looked way worse and still really fixed. Used Nettle props both times, probably about 150-200 with shipping factored in.Quote:

That's good to hear, wasn't too excited about dropping another $500+ for a new one!Quote:

Sorry, the get the prop off comment was for World'sQuote:

Thanks for the tip, that will probably be the cheapest thing I have bought for my boat yet!
We don't have too many weekends left as the lakes seem to keep dropping around here. If I'm not getting any noticeable vibration from the prop, is it alright to keep using it until the season ends? Otherwise I would need to buy another one now.
Good to hear man. I can't believe the key broke so cleanly. I'm glad you fixed the puller and gave it a second try.Quote:

Now it's off, it will be an easy fix for someone with the right pitch blocks.

OK so got prop back early this week just haven't had time to put it on and test it took off today to do just that. i started thinking i should make sure alignment is good before i go to lake and pretty sure my #$%# is %$#%. the motor mount bolts that hold the motor mounts into the side are all bent some worse than others but doesnt look good. I did measure the coupler's as shown in other threads and all seems to be uniform nothing out of wack now i do not have a gauge but used a business card and stayed snug all the way around. I also do not think that this prop strike we took could do this to these bolts. Any advice on where to start maybe with insurance LOL!!!! really not funny but im not happy right now. should of gone to work.Attachment 18361Attachment 18362Attachment 18363
I don't know. I'm wondering if the bolts were loose when the strike occurred?
The crooked bolts is a factory thing , my 2012 is the same brand new .
