The part number 848M0092077 (also written as 84-8M0092077) is a genuine Mercury Marine Wire Harness-Trim (or Trim Harness Assembly). This is not the trim relay itself but the wiring harness that connects to and supports the trim relay system (often including or wiring the relays for up/down trim functions in the power trim/tilt setup).

This harness is commonly used in Mercury outboard models in the 100-125 HP range, particularly two-stroke engines (including 3-cylinder and 4-cylinder configurations). Specific fits include:

  • 100 HP, 115 HP, and 125 HP two-stroke models (frequently listed together as compatible, e.g., "125 115 100 hp Mercury TRIM HARNESS").
  • 75 HP (3-cylinder) in certain serial ranges (e.g., 1B000001 & up USA).
  • 65 HP Jet (3-cylinder) models (1B000001 & up USA).
  • Related older/superseded harness references like 84-819514A15 appear in parts diagrams for similar engines, indicating this is a replacement or updated version for those trim systems.
