Hey Troy, thanks for reaching out and providing all of the photos!

Here are the parts I recommend for getting your boat trailer setup with hydraulic brakes:

- DeeMaxx Disc Brake Kit # DE66YR (need 1 kit per axle)
- Hydrastar Electric Over Hydraulic Actuator Kit for Disc Brakes # HBA16-252-82
- Trailer Wiring 7-Way Upgrade Kit # ET7WK

The DeeMaxx disc brake kit gives you more power than a standard drum brake kit, and the Maxx Coating is the best on the market so you know your brakes will be in good shape for a long time. The reason I recommend using the Hydrastar system is because it is controlled by an electric brake controller (so you have more say in when the brakes are applied), plus you'll keep your standard coupler instead of having to remove your current coupler and replace it with one that actuates.
