Description
Product Overview
The NQEUEPN drain plug gasket set is engineered for marine applications where reliable sealing is critical. Crafted from high‑grade rubber, each washer offers superior elasticity and resistance to oil, heat, and vibration. The pack contains ten gaskets, each measuring to match the standard drain plug dimensions of Mercury 115FS, 150 EFI, Mariner outboards, and MerCruiser stern drives. With a lightweight design of just 0.317 ounces per piece and compact packaging (2.91 x 1.85 x 0.28 inches), these gaskets are easy to store and handle.
Usage
These gaskets are ideal for routine maintenance, engine overhauls, or emergency repairs on outboard and stern drive engines. Install them when replacing the drain plug to ensure a leak‑free seal, protecting the lower unit from oil loss and contamination. Suitable for both professional marine technicians and DIY boat owners, the gaskets perform reliably in saltwater, freshwater, and varying temperature conditions.

FAQ
What engines are compatible with these gaskets?
The gaskets are designed for Mercury 115FS and 150 EFI four‑stroke outboards, as well as Mariner outboards and MerCruiser stern drives.
Can I use these gaskets for other marine brands?
While they are optimized for the listed models, the dimensions may fit other engines with similar drain plug specifications. Verify measurements before installation.
How do I install the gasket?
Remove the old drain plug, clean the sealing surface, place the new rubber gasket onto the plug, and reinstall the plug to the recommended torque. Ensure the gasket sits evenly to avoid gaps.
Are these gaskets reusable?
For best sealing performance, we recommend using a new gasket each time the drain plug is removed. Reusing can compromise the seal due to material fatigue.
