09-814B Johnson Pump F9B High-Pressure Neoprene Impeller | Genuine OEM Marine Part

🔧 Product Description

Aftermarket F9B High-Pressure Neoprene Impeller - Replaces SPX Johnson 09-814B

Twelve-blade high-pressure impeller for Johnson F9B pumps. It has the same principal 95 × 88.5 mm envelope as the nine-blade 09-802B but uses a denser vane configuration for higher-pressure duty.

⚙️ Key Features

• Material: neoprene, cooling-water service
• Outside diameter: 95.0 mm / 3.74 in
• Width: 88.5 mm / 3.48 in
• Hub bore: approximately 25 mm
• Drive: internal spline
• Blade count: 12

🚤 Compatibility

Commonly used on

• SPX Johnson F9B high-pressure pumps
• Jabsco pumps specifying 21676-0001 or 17936-0001
• Heavy-engine pumps carrying the listed Caterpillar, Cummins, Detroit Diesel, Perkins, Volvo Penta or Yanmar references

Application Details

• Pump / Service Type: High-pressure raw-water cooling and clean-water transfer
• Identification: Confirm 95 × 88.5 mm size, spline and 12-blade high-pressure configuration.
• 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
