Volvo Penta water-separating fuel filter 3847644 — Two-Pack OEM for stern drive, marine-grade water removal

Genuine Volvo Penta water-separating fuel filter 3847644, sold as a factory two-pack to protect stern drive engines from water and debris in fuel.

Keep your marine propulsion running reliably with this authentic Volvo Penta replacement fuel filter. Manufactured to the brand’s original specifications, the 3847644 unit removes free water and particulate contaminants before they reach the fuel system. Supplied as a matched pair, these filters let you service both primary filter locations or keep a spare on board for routine maintenance or unexpected replacements. This listing is for genuine OEM parts, not aftermarket copies, so you receive the fit, materials, and performance Volvo Penta designed for its stern drive lineup.

How does this filter protect my stern drive engine?

The 3847644 separates and traps water and solids that would otherwise enter fuel lines, injectors, and pumps. By preventing water and debris from circulating in the system, it reduces the risk of clogged injectors and fuel-system wear.

• Water-separating media designed for marine fuel conditions
• High-efficiency particulate capture to protect injectors
• Factory tolerances ensure correct seal and flow for Volvo Penta systems

Will these filters fit my Volvo Penta stern drive?

These are OEM units produced to Volvo Penta part number 3847644, intended for compatible stern drive models. Always cross-reference your engine’s parts list or VIN to confirm fitment before installation.

• Part number: 3847644 (two-pack sold together)
• Designed as direct replacements for Volvo Penta fuel-filter housings
• Verify compatibility with your engine manual or dealer parts lookup

How often should I replace the fuel filter on my boat?

Replacement frequency depends on fuel quality and operating conditions, but routine inspection at each season and scheduled replacement per Volvo Penta guidelines is recommended. Replace sooner if you notice water, poor engine performance, or after refueling from questionable sources.

• Inspect visually during regular maintenance intervals
• Replace if water or heavy contamination is present
• Keep a spare on board for emergency swaps during trips

What are the benefits of buying an OEM two-pack instead of a single filter?

Purchasing the two-pack provides matched filters for dual-filter systems or a ready spare for rapid replacement. OEM parts deliver consistent materials and sealing surfaces that match factory performance and help maintain warranty and service standards.

• Two filters for paired installations or immediate backup on board
• Factory quality minimizes mismatch risks and sealing issues
• Reduces downtime with a prepared replacement at hand

Who is this for: Boat owners, marine technicians, and fleet operators using Volvo Penta stern drives who prioritize genuine replacement parts for dependable fuel-system protection. If you operate in coastal, freshwater, or variable fuel-quality environments and want factory-fit components that meet Volvo Penta specifications, this OEM two-pack offers a straightforward maintenance solution. Confirm fitment with your engine documentation or a Volvo Penta parts advisor before purchase to ensure correct application.
