Ranger boat trailer jack

Has anyone with a Ranger boat trailer changed out their jack?  I would like to know how to do so.  Any help would be greatly appreciated.

Ironically I replaced mine last week when the wheel snapped off. I called down to MW Marine as I live in Waukesha (not sure on your location) and gave them the year and make of my Ranger 2009  1860 Angler. Parts department looked it up and they had it in stock. However, there are two options I made the mistake of not brining the brackets and the old jack with me had to make two trips there. Also I upgraded from 1250 lb  to a 1500 lb and it has bigger wheel for moving it around.  

I swapped mine out last year.  I had to call Ranger direct and order one as the standard ones wouldn't fit the trailer.

not sure what you are looking for or what your issue is, but did find a couple links that might help
