Marinco Y504-2-504 EEL 50A Shore Power Y Adapter

The Marinco Y504-2-504 EEL Y Adapter is a 50A 125/250V splitter, taking one dockside connection to two locking female connectors on the boat side.

This is a connection adapter rather than a voltage converter, and that distinction matters. It changes the shape of the connection, not the electrical supply behind it. It should be chosen by matching the exact shore-side and boat-side connector requirements of the vessel, not by amperage alone.

One locking male plug takes the dockside receptacle or cordset, and two locking female connectors feed two compatible boat-side circuits from it. That suits a boat with two separate 50A shore inlets and a dock supplying a single connection.

Both female connectors carry sealing collars so they attach securely to boat inlets or cordsets while protecting the connection in wet conditions. Marinco rates the adapter for wet locations specifically, which makes the sealing hardware part of the assembly rather than an optional extra. Explore more shore power adapters.
