One of my aluminum props has some nasty kinks, the biggest is about 1/4 inch. Is there anything that I could use to fill these spots, short of aluminum welding which I have never been able to master?

Re: Fixing props

Welding is the only "durable " fix from what I know. I have a friend that does them for me. I can weld but not as good as him. He seems to be able to weld "rust to corrosion" and give a lasting repair.

Re: Fixing props

Aluminum welding takes a lot of practice. You have to start the tig torch at a higher current then, as the base metal heats, up decrease the current to keep the arc at just the right temp. As the thickness of the base metal changes you have to keep adjusting the arc to keep the temp just right. A tig unit with a foot pedal control for the arc current is almost mandatory. That's a lot of money. There aren't any fillers or epoxies that will stand up to what a prop has to endure so welding is really the only option. Have someone do it for the $75 or if you run in "chunky water" a lot look at a composite prop. A set of replacement blades is around $75 but you save yourself the down time if you keep a set on hand. A stainless prop is ok if you run where the debris in the water is small but if you hit something big with a stainless prop all that force is transfered to your lower unit---thats bad. Like ken said some guys can do magic with welding and that experiece and their equipment is what we pay them for.

Thanks guys. It is as I expected but I thought maybe, by now, someone would have produced something that would hold.....

Re: Fixing props

Finding a good aluminum welder is all important. Tig welding is the only way to go.

Theres alot more to it than just welding.it needs to be done by a skilled prop shop.to make sure the pitch on all the blades is right.just my 2 cents

Re: Fixing props

The amount of money you save fixing the prop yourself will get eaten up by the repair bill of the lower unit bearings you will have to replace.

Do yourself a favor and have a prop shop repair and balance the prop for you.
