Marinco CS503-25 Yellow 50A 125V Shore Power Cordset

The Marinco CS503-25 EEL ShorePower Cordset is 25 feet of yellow 50A cord at 125V, with a jaw-clamp locking connection.

This combines two restrictions worth noting together: 125V single voltage rather than 125/250V, and 25 feet rather than 50. Both are correct choices for the right berth, but a boat with 125/250V service or a distant pedestal needs a different cord, and neither difference is visible on the connector.

The Easily Engaged Lock uses a jaw-clamp wing that operates one-handed and locks onto a standard compatible inlet with a twist, rather than a threaded ring needing several turns. A secondary locking feature adds retention once engaged, keeping the connection secure as the boat moves in a slip.

Because the EEL system fits standard NEMA inlets, the cordset upgrades a connection without replacing the boat-side inlet. An integrated LED cord light guides the connector into place after dark and shows when the cord is still connected. UL approved and built to ABYC standards.
