I just noticed a big chunk out of the gelcoat on the bottom of my boat about baseball sized. I was confused about how that happened until I saw it above the axle on my trailer. When the boat bounces the axle comes up and hits the boat on violent bumps. Does this mean I need new leaf springs or just a roller or bumper on the axle? How much have leaf springs cost on a 18 foot single axle trailer?![]()
