Volvo Penta 24509844 is a genuine OEM hose used in Volvo Penta D4 and D6 raw-water cooling and exhaust-side service. Current Volvo Penta parts references show that earlier hose 21768904 has been replaced by 24509844, and the strongest public diagram trail places the earlier number in the D6-280A-A / Marine Propulsion exhaust-pipe assembly as schematic object key 11. Additional current cross-reference coverage also identifies the earlier hose as a cooling water hose for Volvo Penta D4 and D6 applications, making 24509844 the current OEM replacement where that exact hose is called for.

Engine Compatibility
The strongest supportable fitment trail for Volvo Penta 24509844 is through the earlier number 21768904, which is shown in the D6-280A-A / Marine Propulsion exhaust-pipe assembly. Current cross-reference coverage also associates that hose with a broad group of D4 and D6 applications, including D4-210A, D4-225A, D4-260A, D4-300A, D6-280A, D6-300A, D6-310A, D6-330A, D6-350A, and D6-370A variants, plus some DPH and DPR-linked propulsion packages. Because that wider model list comes from aftermarket cross-reference fitment rather than the same Volvo schematic page, the safest fitment standard is the exact Volvo Penta serial-number-based parts diagram for the engine and hose routing being serviced.
Serial Number Fitment Notice
Fitment can vary by engine version, propulsion package, and hose-routing layout. Confirm Volvo Penta part number 24509844 against your engine serial number and the correct Volvo Penta cooling or exhaust-pipe diagram before ordering, especially on D4 and D6 installations where several nearby molded hoses can look similar once removed.
When This Part Needs Replacement
Replace this hose when the original hose shows swelling, hardening, cracking, clamp-area wear, seepage, abrasion, or age-related deterioration. It is also a smart replacement during adjacent cooling-water or exhaust-pipe service if the original hose has already been disturbed or shows visible wear.
Installation Notes
Match this hose to the exact Volvo Penta application before installation. The strongest public reference trail ties the earlier superseded number to the D6-280A-A exhaust-pipe assembly, while cross-reference coverage also supports D4 / D6 cooling-water use, so confirming the exact diagram position and hose routing first is the safest cross-check before ordering or reassembly. Inspect the related clamps and adjoining pipe connections at the same time to help avoid repeat leaks after service.
Alternate/Superseded Part Numbers
Current Volvo Penta parts references show 21768904 as the earlier number updated to 24509844. Use 24509844 as the current primary OEM ordering number for this listing.
Parts Desk Insight
Molded hoses around D4 and D6 cooling and exhaust-side assemblies are easy to mis-order because nearby hoses can look close by shape alone. Matching the exact Volvo Penta diagram position first is usually much safer than comparing bends and diameter by eye after teardown.
