Alejandro, in order to find out what size brakes your boat trailer needs you can either pop off your hub and measure the width and depth of the drum, or, you can let me know what size axle you have and we'd be able to find out what size brakes you need.
If you can get let me know what that is in the comments, I'd be happy to find a good set for you.
