Hi,
I have a new to me boat with a tandem axle surge brake trailer. I'm having a weird issue where I can't close the coupler on the ball if I jack it all the way down onto the ball. I have to basically lower it on the with the jack, close the ball, then finish lowering the jack and stowing it. The issue is the bottom tongue of the coupler is hitting the base of the ball and won't close. So by using the jack to keep it up a bit, I can get it to close.
I haven't had this issue with any other trailer I've used. The coupler that came on the boat was messed up (needed a hammer to close it and a screwdriver to open it), so I replaced it with a new one. The new one has the same issue.
So I'm wondering if I need a taller ball, or if this is normal behavior for this style of trailer tongue. This is the first time I've had a trailer with this kind of tongue. See pic:
