Sierra makes OEM-replacement engine parts that cross-reference to the original numbers. Find the gasket, seal, or O-ring for your motor and skip the dealer markup.
Sierra has built aftermarket marine engine parts for decades. The catalog covers gaskets, seals, O rings, and small components that keep an outboard or sterndrive running. The main value of Sierra lies in cross reference. Their parts replace the original equipment piece and deliver the same fit and function, usually at lower cost than a dealer. The key to ordering correctly is matching the part to your engine.
The fastest way to get the right part is the original equipment number. Sierra lists the OEM numbers each part replaces. If you have the Mercury, MerCruiser, OMC, Johnson, Evinrude, or Yamaha part number from the old piece or the parts diagram, you can match it directly. Pulling the number off the worn part beats guessing every time.
If you do not have the OEM number, you need the engine make, horsepower, model, and year to narrow it down. Marine engines changed components across model years, so the year matters as much as the horsepower. Have that information in hand before you order so the gasket or seal actually seats.
This collection focuses on the sealing parts that fail with age and heat. Examples include water pump gaskets, oil pan gaskets, carburetor mount gaskets, powerhead seals, and O rings. When you are in there for one repair, replace the related gaskets and seals around it while the unit is apart. It is cheap insurance against pulling the same cover twice.
For common jobs like a water pump rebuild or a powerhead reseal, Sierra offers gasket sets and kits that bundle every piece the job needs. A kit saves you from discovering a missing O ring halfway through the rebuild with the boat in pieces.
Sierra parts are built to marine standards, not generic automotive substitutes. They handle the heat, vibration, and corrosion a marine engine produces. That quality lets them stand in for the OEM piece with confidence.
Not sure which part fits your motor. Give our crew your engine make, model, year, and the OEM number if you have it. We will match the exact Sierra part so the repair goes back together right.
The fastest way is the original equipment number. Sierra lists the OEM numbers each part replaces, so match the Mercury, OMC, or Yamaha number off the old part or parts diagram. Otherwise use your engine make, model, horsepower, and year.
Sierra parts are engineered to replace the original equipment piece with the same fit and function. They are built to marine standards rather than generic automotive substitutes and handle the heat, vibration, and corrosion a marine engine sees.
Marine engines changed components across model years, so the same horsepower can take different parts depending on the year. Have the make, model, year, and OEM number ready so the gasket or seal seats correctly.
Yes. When a unit is apart for one repair, replace the related gaskets, seals, and O rings around it. It is cheap insurance against having to pull the same cover again a season later.
Yes. For common jobs like a water pump rebuild or powerhead reseal, Sierra offers gasket sets that bundle every piece the job needs, so you are not stuck mid rebuild missing one O ring.
