Dometic DK4720 Actuator Kit 7/16" Mount Bolt, 3/8" Socket
The Dometic DK4720 is a genuine OEM replacement actuator kit designed for SeaStar and Detwiler hydraulic jackplates. This complete assembly features a 7/16" mount bolt and 3/8" socket configuration and is engineered as a direct-fit replacement for later-model SeaStar hydraulic jackplates. It applies to all jackplates with serial numbers above D4000-001843 and any jackplate with a serial number beginning with "JP". Because actuator design changed over time, always confirm the jackplate serial number before ordering to ensure correct fitment.
The DK4720 kit includes the integrated hydraulic pump, actuator, and electric motor, restoring full functionality to the jackplate system. It is the most reliable way to bring a worn or failed actuator assembly back to factory performance. The hydraulic wiring harness is compatible with all pumps and actuators in the SeaStar lineup. Engineered to OEM specifications, this actuator kit delivers smooth, dependable hydraulic lifting performance for precise engine height adjustment under all operating conditions and loads.
Proper engine height is critical to maximizing boat performance, achieving shallow-water operation, optimizing top speed, and improving fuel economy. The DK4720 restores the hydraulic lifting capability needed to take full advantage of the jackplate system. For earlier jackplates with serial numbers D4000-00001 through D4000-001843, the DK4710 actuator kit with a 3/8" mount bolt and 5/16" socket is required instead.
