Yes, you can replace your hydraulic brakes with electric brakes. You will need to know your axle capacity and have the appropriate brake mounting flange. For example, with a 12" x 2" drum there is the Electric Trailer Brake Kit # AKEBRK-7-SA, which is for axles with a 5,200 lb - 7,000 lb capacity and will work with a 5-bolt mounting flange such as # 4-44-1. You will also need a brake controller, breakaway kit and wiring, some of which is vehicle-specific.

Second, in order to find the correct hub and drum for your Escort boat trailer, you need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached to see exactly where you need to measure.

I have added a link to a help article for you to check out that details all the parts you'll need to add electric brakes, and if you have any further questions please let me know.
