Welding in Bilge??
I can think of a couple of reasons why this would not be a good idea, but one of my fabricated offshore motor mounts has a cracked weld and needs repair. I would hate to have to pull the one engine to fix this, as it is not going to take more than 5 minutes to fix in the boat. Anyone have any horror stories as to why I should not do this?

depends on what you want to believe... first i would stop drill the crack. then if you believe you can effectively weld that piece from one side only, just clean it effectively and have at it.
disconnect the batteries, alts and electronics ( assuming arc or tig welding) and try not to light anything on fire with the sparks and you should be fine.

If you don't completely disconnect all the wiring, including grounds to delicate electronics (ignition modules, distributor pick-ups, stereo, etc) you are running a high risk to damaging them, especially if you use an older style stick or MIG welder. Welding creates huge currents. Just disconnecting the battery is not enough.

Yea, what he said, and pull your compass out too if you use it with any accuracy. Lay some wet canvas down under the area to catch any weld spatter (if you use arc).

Well, I got the job done this evening and all is well! I wasn't taking any chances and wraped the fuel lines with tin foil, and put a large disposable aluminum turkey pan between the mount and the hull to shield the sparks! Sure was easier than pulling the engine! Thanks for all the advice.
