Was down at the lake yesterday and my v-drive slipped out of gear when the water got a bit rough. I have a thoroughbred box in it, and my question is do these have an adjustment on them like the casale's do with the ball bearing on the shift arm? My toploader box has this with an adjustment screw so you can tighten it down on the ball to make it stay in gear, but this also make it harder to put in gear. Any info would be great. Thanks.
