Best Use Case
The right choice when you need a locking fuel fill cap — ideal for boats stored in marinas or shared facilities where fuel security matters. The cast stainless construction makes it the premium option for saltwater environments where chrome-plated or plastic caps corrode prematurely. Use as a direct replacement for a lost or worn cap on compatible Seachoice fill plates.
Parts Desk Insights
This is a locking cap — confirm your fill plate model is one of the compatible Seachoice series (32251, 32261, 32271, or 32281) before ordering, as cap thread sizes vary between fill plate series. For non-locking alternatives, see the Seachoice 50-32501 Non-Locking Black Plastic Cap (fits Seachoice 32011 / Perko 1313/1314) or the Seachoice 50-32521 Chrome Zamak Tethered Cap (fits Seachoice 32041).
