How do they repair them, I rum all allumnum props on my merc. I hit so many stumps that the picth is off and it has slowed the boat down a great deal. I can put them in a vise and take a rubber mallet and beat them back out and they run great until I hit the first stump and they go right back to were they where.
It takes many stump hits to get them bent but once bent when I straighten them out it only takes one hit to bend them again.
So If I pay someone to fix my prop will it be any better???
Will it last any longer?
and what is the avg. cost to have this done?

I would give up on aluminum and buy a stainless.

Even if you bend them back i would still have them look at it and balance it. I know it doesn't take much of a hit to throw them out of balance and after you run it for some time it gets the bearing and shaft in your foot.I'd rather be safe then sorry. and x-2 on spurhunter comment

Stainless is only for open water, if you hit what I hit with a SS prop you will tear up way more than just the prop. Aluminum is the only way to go in stump infested waters imo

06. The ones i've had repaired have been great,just good as new. I have fished for catfish below the dams and the rocks are worse on a prop than the stump.I keep a spare ready to go just in case I need it

Bending metal back and forth while cold creates stresses in the metal that weaken it. That's why blacksmiths heat the metal in fire before hammering it (that, and it makes it easier to manipulate by softening the metal).

Modern welders do the same thing with certain welds - it's called "stress relieving".

What you are doing is not really any different than bending a paper clip back and forth - each time it is bent it becomes weaker. I suppose a fracture or complete break is very possible.

I don't know anything about prop repairs, but I would guess that they are heated as part of the process with a torch or kiln or something.

I'll tear up one or two a tear.. the last 3 I have bought were the composite props.. they work perfect and are only about $125..cheaper than getting one repaired..

I used to heat with map gas and bend back when I ran my old stum jumper. That helps relive the stress and the memory of the bend. Now I run a stainless and stay out of the stump fields unless I am on the trolling motor. Sometimes I sure miss that old flatbottom and 35 hp eveinrude!!
