Sea-Dog 426142-1
A complete two-conductor deck outlet with keyed unequal pins, gasket and water-resistant cap; mounts with two #6 round-head screws (not included).
Identify Sea-Dog Polarized Deck and SAE Electrical Connectors
Marine electrical connectors may have unequal pins to prevent reversed mating, but that alone does not make every Sea-Dog connector compatible. These four part numbers include two- and four-conductor deck fittings, a four-pin molded plug and a two-wire SAE connector. Match the original pin count, style and current rating before replacing it.
Identify the plug, deck outlet or SAE connector
The table lists exact Sea-Dog part numbers and manufacturer specifications. On narrow screens, scroll the table sideways to see every column.
| MPN | Device / connection | Conductors | Rating | Wire termination |
|---|---|---|---|---|
| 426142-1 | Complete polarized deck outlet | 2 | 3A; 12/24V DC | 14 AWG maximum; set-screw |
| 426164-1 | Polarized molded plug connector | 4 | 5A; 12/24V DC | 14 AWG maximum; set-screw |
| 426234-1 | Polarized four-conductor deck outlet | 4 | 5A; 12/24V DC | 14 AWG maximum; set-screw |
| 426880-1 | SAE polarized two-wire plug/socket | 2 | 20A; 12/24V DC | 16 AWG AWM; 12-in leads |
Pin count is only part of the match. The 426164-1 and 426234-1 both use four conductors and are 5A/12–24V DC, but one is a molded connector while the other is a deck outlet. The 426142-1 is a 3A, two-conductor complete deck outlet; 426880-1 is a 20A SAE-style two-wire plug/socket. Their mating systems are not assumed interchangeable.
Manufacturer drawing measurements: 426142-1 A = 1 7/16 in, B = 1⅜ in; 426164-1 A = 1¼ in, B = 1 3/16 in; 426234-1 A = 2 1/16 in, B = 1⅞ in. The SAE 426880-1 is A = 1 1/16 in, B = ⅝ in, C = 5/16 in. Check the accompanying drawing to see which feature each letter refers to.
See the manufacturer technical drawings: Two-conductor deck outlet and Molded four-pin connector and Four-conductor deck outlet and SAE two-wire connector.
Inspect the removed part before replacement
- Check the old part's full manufacturer number and count the conductors or pins.
- Determine whether it is a fixed deck outlet, a molded multipin connector, or an SAE-style plug/socket with cable leads.
- Confirm the rated circuit: 3A for 426142-1, 5A for 426164-1 and 426234-1, and 20A for 426880-1.
- Match wire attachment: 14 AWG maximum set-screw terminals are different from 16 AWG tinned SAE leads.
- Inspect the mating part, cap, seal and mounting method before replacing any connector.

Sea-Dog 426164-1
Four unequally sized polarized pins in a molded connector. Other pin-count versions exist but are separate MPNs.
Sea-Dog 426234-1
Four-conductor deck outlet with a capped body, not the same mounting arrangement as molded 426164-1.
Sea-Dog 426880-1
Weather-resistant two-wire SAE plug and socket with tinned lead wires; not interchangeable with the 3A two-pin deck outlet.
Related marine electrical references
For a separate 12V accessory receptacle or USB charging outlet, see the Sea-Dog socket identification guide. A polarized 3A, 5A or SAE connector is not a replacement for a higher-current power socket unless the full mating and circuit specifications match.
