Sounds like your problem is the ramp.
How low is your hitch and how close is your prop guard? If your slanted to far forward the angle of the boat may not allow it to slide off. If its low you may try to get a different ball mount, raising it up higher, of air shocks on the vehicle. Just make sure your prop guard still has some clearance. Not sure the problem is in your tongue.
If its not a competition ski boat, its always second best.
