I have to repair a cracked aluminum engine block. What alumunum epoxy should I use?
cracked where? i could suggest the wonder rods, such as dura-fix. i've used them on some aluminum repairs in the past. when the thickness of the materials is uniform, its a good easy to use product. when the thickness changes, its useless. i wouldnt think of using it on a motor repair though. melting temp is a bit low, much closer to combustion temps then alum's melting temp. the truly best way to fix anything alum is with a TIG welder in the hands of somebody who knows how to use it. but, any good welder will probably look at you like you are nuts when you bring a motor in to be welded. depending on exactly what you have, the entire powerblock, which is the motor part, might be avaible for purchase to replace your old one with. it may be priced at under a $1,000. you would end up with a brand new motor. for outboards, when teh drive is in good condition, this can be a great way to get a brand new outboard performance at a far cheaper price.
elmers glue! Lol. I believe you can have it welded. That will last for a while.or until you can get another one.
