Default any one ever extend the tounge on a boat trailer?.....

I am looking at extending the tounge on my trailer, it is 3x5 square tubing, It looks like I can just get a length of tubing and drill it like the old one. Any suggestions before I take this on???
Any pointers or words of wisdom.....Thanks

I think you want East Coast Marine in Delaware.
I'm going to have to do this with one of my trailers, but I'm gonna get the tubing from my local steel supply. They have it galvanized too. I'll just replace the original tongue with the longer one since I don't trust having a butt joint.

never just weld a section to extend it, replace the entire bar or do a reinforced angle join, or you will end up with a cracked weld.

Most trailer mfg's advertise that you can get extended tongues, so it seems like (within reason I'm sure) its a perfectly normal thing to do. In fact, I'm picking up a new trailer this Saturday where the mfg has installed a 2' longer tongue for me.

Like others have said - don't weld it to extend, replace with a single piece unit.

Just for my information, I am in commercial construction and have always been told a weld (if done correctly) is stronger than the metal itself. Any reason why everyone recommends not welding?

Mine is designed to extend and has a "sleeve." I'd suggest a sleeve joint over a butt weld joint. Bolting or welding should be just as safe.

Good luck!

There is no reason you can't buy a section of 3x5 and replace the one you've got. Be reasonable about it though - unless you are towing a very light load, I wouldn't extend a tongue more than a foot or so, since obviously you will alter the weight distribution of the trailer and the stress on various members.

I would not "extend" an existing one, it's just not worth the effort and risk that your "extention" would go bad, just pick up a longer piece of galvanized tubing and go to town. (I think this is what you really meant in the first place)

when you weld the stell becomes very hot (of course) it will then cool and be brittle, and will crack after a short time (if it does not just snap off) you will need to do a joint with "fish plates" on either side for strength

What we do here in Hawaii is a sliding tongue. Smaller square tubing within a larger piece. It is held together by two pins, at two different lengths of the tongue. You can be creative and make extra holes to adjust the tongue length but doing so weakens the strength of the extension. Most just make the two holes. We can extend the length up to 10 feet or more if needed when launching at South Point..... with a slight bow in it. So when travelling it is kept at the shorter length.

I don't think you can weld galvanized steel without giving off toxic fumes. Ane even if you did weld it, the area of the weld would no longer be galvanized.

Replacing the tongue with a longer piece of tubing is the best solution.

Others have pointed out that there will be more weight and stress on the longer tongue. Without having an engineer check it, it wouldn't be a good idea to make it more than a foot or so longer than the original unless it's for a lightweight boat.
