Volvo Penta — Water Inlet — 3863104

The Volvo Penta 3863104 Water Inlet is a genuine OEM cooling-system component designed to maintain proper raw-water flow into the cooling assembly. A factory-matched replacement ensures the correct connection geometry, material compatibility, and sealing interface for reliable service life in marine propulsion applications.

Compatible Applications

  • Selected Volvo Penta marine propulsion engine packages
  • Raw-water cooling circuit applications where part number 3863104 is specified
  • Fitment varies by engine model, drive model, cooling layout, and production serial range — always confirm compatibility against the correct Volvo Penta parts catalog entry for your specific engine and serial number

Part Details

  • OEM Part Number: 3863104
  • Product Type: Water Inlet
  • System: Raw-Water Cooling
  • Weight: Approx. 0.020 kg
  • Condition: New — Genuine Volvo Penta OEM

Key Features

  • Genuine OEM fit: Factory-specified geometry and materials for the intended cooling-system position
  • Correct flow path: Maintains raw-water inlet flow as designed for the application
  • Sealing integrity: OEM connection style supports proper hose and seal interfaces
  • Direct replacement: Drop-in swap for the original part when damaged, corroded, or cracked
  • Serial-number verified: Part is identified by Volvo Penta against engine and drive model with serial break

When This Part Needs Replacement

Replace the water inlet when the original part shows cracking, corrosion, leaking at the connection point, or physical damage that prevents reliable raw-water flow. Inspect during annual service or whenever cooling-system overheating or reduced flow is suspected.

Installation Notes

Compare the new part to the original before installation. Inspect adjacent hose connections, sealing surfaces, and nearby cooling-system components. Install into a clean, properly supported assembly and confirm all connections are secure before returning the system to service.

Alternate and Superseded Part Numbers

Current Volvo Penta references identify this item as 3863104. Confirm any supersession or cross-reference details with the Volvo Penta parts catalog for your specific application before assuming interchangeability.

Technical FAQ

  • How do I confirm this fits my engine? Locate your engine model and serial number on the engine label, then verify 3863104 appears in the correct parts diagram position for your cooling circuit.
  • Is this a genuine Volvo Penta part? Yes — this is a genuine OEM component, not an aftermarket substitute.
  • Can I use an aftermarket water inlet instead? OEM is recommended for cooling-system components where geometry and material compatibility directly affect sealing and flow performance.
  • What if my part number has been superseded? Volvo Penta periodically updates part numbers. If 3863104 has been superseded, the current number will appear in the parts catalog — confirm before ordering.

Parts Desk Insights

Best use case: Direct OEM replacement for the raw-water inlet position where 3863104 is specified in the Volvo Penta parts diagram for the engine and cooling configuration.

Most common mistake: Ordering by part name alone without verifying by engine model and serial number. Water inlet geometry and connection style can vary between engine families and production ranges — serial-number verification is the only reliable confirmation.

Fitment guidance: Locate your engine ID plate, note the model and serial number, and cross-reference 3863104 in the correct parts catalog section before ordering. If your serial range falls on a production break, confirm whether a superseded number applies.
