I recently purchased a used aluminum Jon boat. It has a pinhole about 6 or 8
inches away from the drain plug hole. If a person was inclined to try and
repair this pinhole, what would be the best method.

I have used Devcon (an aluminum putty) for other repairs (not on boats). I
also have access to aluminum welding process.

==========================================

An aluminum weld is probably the most professional approach IF you
have the proper eqipment, skills AND knowledge of what aluminum alloy
you are dealing with. Not all alloys are created equal and some are
almost impossible to weld.

If it was my boat I'd probably be inclined towards a cheap and dirty
approach such as drilling out the pinhole, tapping threads for a small
stainless machine screw, and securing with lockwasher, nut and a dab
of 3M 5200. Also put some 5200 on the machine screw before you thread
it in.
