    Default Hey pump dudes.....? for ya

    While at the CP deal, my boat started taking on water. I brushed it off as a leak somewhere..

    Well with my brothers keen eye, he found that the suction housing was cracked. So i opted not to run the thing anymore for saftey reasons.

    I pulled the pump out and there seems to be a casting flaw in the suction housing that is letting water trickle through. Can this be welded and considered a "good fix" and not crack again or is my only option to replace the suction housing? The crack is about 3 1/2" long and the loader is nowhere near the crack, and you can tell it was a casting flaw that just decided to crack.
    the reason i mention the loader is, i have seen them rub the S/H and crack them...
    Thanks.....

    I had just asked my welder about welding on cast aluminum. He seemed a bit scetchy about it. Said you have to get the dang thing so hot you risk cracking other spots. He said it could be done by the right person with the correct equipment but was hesitant to how long it would last.

    My question did not pertain to a pump so maybe they are different but at his warning i just decided to buy a new peice.

    Let me see if i can find his exact email..



    Edit: I will revise my statement. He said he did not have the equipment and that if i was going to have it done then someone else would have to do it as his equipment was not suitable for the repare and that is why he would not trust his repair on that peice. I missunderstood his comments until i re read it.

    im a certified welder and welding instructor by trade. if it was even my own SH on my low horsepower smallblock i wouldnt do it. i gurantee it will crack again. could be first time you run it, could be 2 years from now, but it will crack again, even if repaired correctly. suction housings can be had cheap too.

    Way too much crap in the Berkeley castings to get a good weld. I think running as hard as you are, a new Dominator housing is in order. These Berkeley castings are not getting any younger, most are 30 plus years old already.
