More about this item

EMP 25-00219-1 O-Rings

O-rings are one of those parts where the dimensions matter as much as the application. Too small and it will not seal. Too large and it will not seat properly. This one is sized precisely for its application: 2.4375 inches inner diameter, 2.625 inches outer diameter, and 0.09375 inches in width. Those are not round numbers, which means this is a purpose-built O-ring for a specific sealing location rather than a generic substitute, and getting the right one matters for a leak-free result.

The EMP 25-00219-1 O-Ring is designed for Mercury and Mariner 2-cylinder outboards in the 18 to 25 horsepower range, covering model years 1973 through 1998. That is a long production run, and these smaller Mercury and Mariner outboards are still common on the water and in service shops, so having the correct O-ring available is genuinely useful. It is a direct replacement for Mercury part numbers 33465, 853220, and 807149, and also crosses with Sierra 18-7163-9, GLM 81430, and Mallory part numbers 9-76548 and 9-76516. If you are cross-referencing from any of those numbers, you are in the right place.

EMP manufactures this O-ring to OEM specifications, so the material, durometer, and dimensions match the original exactly. On a small outboard from this era, a leaking O-ring in the wrong location can cause coolant loss, oil contamination, or fuel system issues, depending on where it sits, so using a correctly spec'd replacement is always the right call.
