I've had this problem all along. I do not believe that my wheel has any flat
spots in it, so this answer may not apply to your situation.

My solution is to turn the wheel in the direction that I am going BEFORE
pushing the boat. Now, how do I do that, one might ask?? Well, I carry a
cut-off golfer's old 9 iron in the tube opening at the top of the winch
riser-post. It has the head, but no grip. The head is big enough so that it
doesn't slide down into the tube opening.

I slide the club's shaft into the -U-shaped area that supports the jack's
wheel, and turn the wheel with the added leverage. It has made moving the
boat around a much easier job. Any piece of strong steel that will fit will
do the same job.

Incidentally, I noticed that a large manufacturer of trailer jacks has come
out with a nut-supported jack. It replaces the "folding stowable style" that
uses a "spring ring" to hold everything together. It is advertised as "the
sturdiest jack" or some-such. Perhaps yours is not the only collapse that
has occurred on certain style jacks.

Sorry to hear that you are laid up.

I was putting my BassTracker Jet away last Sunday evening. Once backed
into
the garage and disengaged from my truck hitch I started to position it
manually by pushing on the bow. I assumed this would be a simple task. My
garage floor is very smooth concrete. At one point I was pushing the
trailer
in a direction that the trailer jack wheel did not want to follow. Instead
of the wheel coming around (like a shopping cart wheel), the trailer jack
apparently bent, then disengaged momentarily causing the trailer to
collapse
onto the top of my left foot crushing a bone. Of course I saw starts,
freaked out a little, no make that a lot, and my wife called 911 (not the
bass club). I am now wearing a knee high cast and hating it.

This probably happened because I once forgot to raise the jack and drove
away. By the time I noticed that I had done this the plastic wheel had
touched down a few times causing some minor flat spots. My guess is that a
flat spot prevent the wheel from turning on the "smooth" concrete whereas
the wheel has always been fine on the rough surface of my driveway. This
was
my fault, I just didn't know any better.

I guess I am partially venting here in the NG because I'm more or less
stuck
in front of the computer with little else to do right now.

Anyway, those of you with entry level boat trailers like mine ought to
take
a good look at your trailer jacks and consider upgrading, especially if
your
jack wheel has any flat spots on it..

Please don't send flowers. Donate LM fingerlings to Van Sciver Lake in PA

you must.
