What This Belt Does
The 24677541 is a genuine Volvo Penta OEM V-ribbed belt that drives the seawater (raw-water) pump on selected D3 marine diesel engines. The seawater pump circulates raw water through the engine’s heat exchanger to keep the engine at operating temperature. Because this belt drives the cooling pump directly, a failed or slipping belt will interrupt raw-water circulation and can lead to rapid engine overheating.
This is the seawater pump belt specifically — not the alternator belt or power-steering belt. The D3 uses separate V-ribbed belts for different accessory positions, so confirming the correct belt for the seawater pump location is important before ordering.
Compatible Applications
Confirm the complete D3 model designation, generation suffix, and seawater-pump belt arrangement before ordering. Volvo Penta D3 engines use several different V-ribbed belts for separate accessories.
- D3-110 / D3-110I
- D3-130 (A–C generation)
- D3-140 / D3-140A / D3-140I
- D3-150 / D3-150I
- D3-160 (A–C generation)
- D3-170 / D3-170A / D3-170I
- D3-190 (A–C generation)
- D3-200 / D3-200A / D3-200I
- D3-220 / D3-220A / D3-220I
- Later D, E, F, G, and H-generation D3 variants — confirm by serial number
Always confirm fitment using your engine serial number and the correct Volvo Penta seawater-pump belt diagram. The D3 uses multiple V-ribbed belts at different accessory positions — the seawater-pump location is the key fitment identifier for this part.
Serial Number Requirement
Match part number 24677541 to your D3 engine serial number and the correct Volvo Penta seawater-pump assembly diagram before ordering. Belt routing and tensioner arrangements can vary between D3 generations.

Service Interval
Inspect the seawater pump belt at every annual service or 250-hour interval, whichever comes first. Replace immediately if cracking, glazing, rib damage, fraying, or contamination is found. Because this belt drives the raw-water cooling pump, do not delay replacement if wear is detected — belt failure at sea can cause rapid overheating.
When to Replace This Belt
- Visible cracking, glazing, or hardening of the belt surface
- Damaged, worn, or missing ribs
- Fraying at the belt edges
- Oil or coolant contamination
- Belt stretching or persistent belt noise / squealing
- Annual service or 250-hour interval reached
- Seawater pump is being replaced or serviced
Installation Notes
- Inspect the seawater-pump pulley, belt tensioner (21424647 on D3-H applications), and pulley alignment whenever the belt is replaced
- Route the belt according to the applicable Volvo Penta engine diagram for your serial number
- Verify that all four ribs are fully seated in the pulley grooves before starting the engine
- Check belt tension after the first run and re-tension if required per Volvo Penta service specifications
- Inspect the seawater pump impeller at the same service visit — a worn impeller and a worn belt often reach end-of-life together
Technical FAQ
Is this the same belt as the D3 alternator belt or power-steering belt?
No. The D3 uses separate V-ribbed belts for different accessory positions. The 24677541 is specifically the seawater pump drive belt (4PK935). The D3 accessory belt 22283751 and the D3 power steering pump belt 22352491 serve different drive positions. Confirm the correct belt for each position using the Volvo Penta belt diagram for your engine serial number.
What happens if this belt breaks?
The seawater pump will stop circulating raw water through the cooling system. Engine temperature will rise rapidly, and the engine will overheat if not shut down immediately. Always carry a spare belt on board for offshore passages.

Parts Desk Insights
The most common issue with this belt is customers ordering the wrong D3 belt because the engine uses multiple V-ribbed belts at different positions. The 24677541 is the seawater pump belt (4PK935) — it should not be confused with the D3 accessory belt 22283751 used in other drive positions, or the power steering belt 22352491 used with certain servo configurations. If a customer is unsure which belt they need, the belt specification (4PK935) and the seawater-pump diagram position are the most reliable identifiers. Also worth noting: when replacing this belt, it’s good practice to inspect the seawater pump impeller at the same time — both are wear items that often reach end-of-life together on D3 engines.
