Sierra 18-2697-1 - Chrysler Force Lower Unit Seal Kit
For seal service on a compatible Chrysler or Force gearcase, Sierra 18-2697-1 brings together four listed oil seals, a water tube seal, washers, a water pump base and an O-ring. It replaces Mercury 26-41365A3 and supersedes Sierra 18-2697, providing clear reference numbers for matching an earlier kit to the current part. Confirm the gearcase application before ordering; the Chrysler/Force designation alone does not establish fitment across every engine.
