So for the first time since I've owned this boat, I decided to leave it in the water overnight at a friends house, and pick it up in the morning. I was going to just drive the trailer home by itself except for one little problem...everytime I got over 25 mph, the trailer started vibrating and jumping all over the place!! It seemed as if the trailer brakes were somehow activated and I was trying to pull it down the road...but it was fine if I went really slow. I could not pull it by itself over 25 mph or it felt like I was going to loose contol. Has anyone heard of this problem, or had a similar issue. I would think the trailers would be able to be pulled by themself, without the boat on them. Once I put the boat on, and add the additional weight, it pulls just like normal! Any suggestions?? Thanks.
