Pistons, Connecting Rods and Bearings shown in this diagram

The source pack contains 5 catalogue pages for Mercury Mariner 75, 80, 90, 110, 115 HP and covers oil filter, cylinder head, piston, main bearing, valve, spark plug and thermostat. The heading defines this diagram route; it does not make every component interchangeable across every version.

Powerhead checks

Confirm the cylinder count, displacement, fuel-system version and serial. Use the exact callout and printed reference because similar powerheads can use production-specific components.

How to use the exploded diagram

  1. Confirm the complete Mercury or Mariner model and serial details.
  2. Find the component and note its numbered callout.
  3. Match the callout to the RECMAR and OEM references in the schedule.
  4. Apply every cylinder, fuel-system, serial and configuration note.
  5. Compare the replacement with the removed part before installation.

Fitment and OEM reference guidance

No single page-level year or serial boundary is printed. Confirm the complete model, cylinder count, fuel system and serial, then apply every narrower row-level note before ordering.

An OEM number is an identification cross-reference, not proof that every scheduled item fits every outboard covered by the page heading. The selected row and exact reference control fitment.

Return to the Mercury and Mariner outboard parts hub, browse the complete exploded diagram library, or use the TMP Global Parts Finder when the exact application is unclear.
