EMP O-Ring Seal, Replaces 910582 326649, Evinrude Outboard Prop and Driveshaft Seal, Part 26-00027

This EMP O-Ring, part number 26-00027, is a replacement seal for Evinrude outboard prop and driveshaft applications. It is designed as a direct equivalent for OEM O-rings 910582 and 326649, giving boat owners a reliable way to reseal the lower unit without sourcing the original manufacturer part. The O-ring forms a critical seal in the lower unit assembly, helping keep gear lube in and water out around the prop shaft and driveshaft area, which is essential for protecting the gearcase from water intrusion and lubricant loss. Each unit is used in a quantity of one per the original assembly point it serves, so a single O-ring covers that seal location during a rebuild or maintenance job. Because seals like this harden and lose sealing ability over time from heat and exposure to gear lube and water, replacing the O-ring anytime the lower unit is opened up for service is standard practice rather than reusing the old one. This part is intended for technicians and DIY boat owners performing lower unit seal kit work, prop shaft service, or driveshaft seal replacement on compatible Evinrude outboards. At 0.031 pounds, it is a small, inexpensive component, but its proper fit and condition directly affect whether the lower unit will hold pressure and stay watertight after reassembly.
