Sierra 8700 4-Cycle Outboard Oil Filter

A purpose-built oil filter for 4-cycle outboard engines, engineered to OEM specifications for correct thread fitment, bypass valve pressure, and flow rate. The Sierra 8700 is a direct-fit replacement designed to maintain proper oil pressure and filtration efficiency through your outboard’s full service interval — protecting bearings, pistons, and internal surfaces from wear and contamination.

Compatibility Note: Engine fitment varies by make, model, and year. Confirm the 8700 is correct for your outboard using Sierra’s current application guide or your engine’s service manual before ordering.

Key Features

  • OEM-specification fitment for compatible 4-cycle outboard engines
  • Correct bypass valve pressure and anti-drainback design for outboard use
  • Engineered for full-interval filtration performance
  • Direct-fit replacement — no modifications required

Parts Desk Insights

Best Use Case: Best suited as a scheduled maintenance replacement during routine oil changes on compatible 4-cycle outboard engines. Because outboard oil filters are engine-specific — differing in thread pitch, bypass valve pressure, and anti-drainback valve design — fitment must be confirmed before purchase. Using an incorrect filter risks inadequate oil pressure or premature filter bypass, both of which can cause accelerated engine wear. If you’re unsure which Sierra filter fits your outboard, use Sierra’s application guide or browse the full family of Sierra outboard filters linked above to find the correct part number for your engine make and model.
