Compact six-blade nitrile impeller for Johnson F3B-19 bilge, deck-wash and oil-change pumps. SPX lists no official Jabsco replacement, so the exact 45.2 × 12.8 mm single-flat geometry must be retained.

  • Outside diameter: 45.2 mm / 1.78 in
  • Width: 12.8 mm / 0.50 in

Application Details

  • Pump / Service Type: Oil, diesel, bilge, deck-wash and compatible utility pumping
  • Identification: Confirm 45.2 × 12.8 mm size and 8 mm single-flat drive.
  • Always compare the removed impeller or pump against the listed dimensions, drive style, material and housing depth before installation.

🔌 Function

The flexible vanes form expanding chambers on the inlet side and contracting chambers on the discharge side. This produces self-priming suction and moves cooling water or other compatible fluids through the pump.

⚠️ Common Signs of Failure

  • Reduced flow or inability to prime
  • Engine overheating or weak cooling-water discharge
  • Pulsing flow, cavitation or unusual pump noise
  • Vanes are cracked, hardened, flattened or missing
  • Hub has slipped, corroded or loosened from the rubber body
  • Impeller has been damaged by dry running, debris or incompatible fluid
