I tried the pads on my trailer,same boat but with all the pads installed my boat would slide back 3 to 4 feet back into the water. I had to give it throttle to keep it in place as I got out and hooked up the strap. I didn't feel comfortable leaving the throttle engaged while I left the seat so I removed all but 2 of the pads and now it doesn't slide back. Steep ramps with all the pads on was real hard to keep from sliding off. Don't know if you had that problem with yours.
