Hey Tracy. In order to recommend a set of I'll need to know what kind of brakes you want; disc or hub. I'll also need to know what size bearings are currently on your trailer so I can find the right brakes. What you'll want to do is pull one of the hubs and look at the two bearings. They should have numbers stamped into the sides of them. I'll need those part numbers to identify your spindle size which will tell me what hub you need.
If they do not have numbers stamped into the side you'll need to measure your spindles using a digital caliper like item # PTW80157. I'll need the C and D dimensions shown in the diagram below.
Who's the manufacturer of your boat trailer? Some use specific axles and brakes that are not compatible with any other brands so I want to make sure you don't have one of those.
