Have had rig out now some with no problems until Monday - when unhooking tongue jack, checking to hear click as well as move it before putting weight on it..........it collapsed to the side the second it came off the hitch ball, missing my feet by maybe 1". I've had bass boats since the late 1970's, a number of them and never had any problems at all with the jacks. I always listen for the pin click plus move it to make sure locked into place so no idea what happened? Very scary as would have taking my feet off if had landed any closer. That's a lot of weight coming down on the tongue. Had a friend come over with 3T floor jack to get it back up and on it's stand as I never leave it sitting on just the jack, use a heavy duty motorcycle stand to set tongue on and block both wheels. Love the boat, handles well, not out enough to check speed yet but Ca. Delta waters can get rough at times. Wanted to let others know to be very careful as could end up being very dangerous with serious injury to someone. Going to have to look for a heavier duty one I can trust, also not sure a 1,000# jack is sufficient.
