I honestly don't even know if this is the right kind of welding, but bottom line is we have a lower housing unit on a B-Max drive, aluminum that needs some welding. Anyone? Preferably in Arizona?

Thanks

I am very capable of welding aluminum but casted aluminum is another battle. It is possible but takes a skilled welder to get the weld properely done.

Where the crack is plays a big roll on how hard it would be to complete the job properely, any pics?

You are talking the right process, Tig or Heliarc, but it is no harder to weld than extruded aluminum like someone else said, same procedures.

It must be clean! no paint, no oil! if it has been leaking oil, the pores in the aluminum will be difficult to clean out but not impossible.

I tig welded a new skeg onto a Mercruiser outdrive for a customer. Did a beautiful job and it fell off with out hitting a thing. Was told that Mercruiser used garbage/recycled aluminum and if you weld with normal aluminum rod it's a bad weld no matter what. I believe the outdrive shops have a special rod to match the Mercruiser aluminum.

No special rod. Did you do a pre-heat/post-heat procedure? what alloy filler were you using?

I have welded literally dozens of them back on with no failures.
