Volvo Penta OEM 90° Hose Connection 872338 | DP DPX SP Sterndrive Transom Cooling Water Plumbing

Volvo Penta OEM 90° Hose Connection — Part 872338

• Part Number: 872338
• Alternate Catalog Format: 0872338
• Brand: Volvo Penta (Genuine OEM)
• Official Product Type: Cooling System Parts — 90-Degree Hose Connection
• Configuration: 90-degree elbow / hose connection
• System: Transom shield / cooling-water hose plumbing
• Position: Transom shield cooling-water hose connection — provides right-angle routing for the cooling-water hose, preventing tight bends at the transom
• Application: DP-A, DP-C, DP-C1, DP-D, DP-D1, DP-E, DP-G, DPX-A, DPX-C, DPX-R, DPX-S, DPX-S1, and SP-C1 sterndrives; selected KAD, KAMD, TAMD, AD31, AD41, and gasoline engine packages
• Supersedes: 872336 (earlier Volvo Penta hose connection, now replaced by 872338)
• Weight: approx. 0.1 kg

Confirm fitment by drive model and transom schematic: 872338 is tied to the transom shield and cooling-water routing rather than to engine displacement alone. Volvo Penta uses different hose fittings across closely related drive generations — matching the exact DP/DPX/SP transom schematic is the safest way to confirm the correct part before ordering. If your Volvo parts diagram or catalog shows 872336, order 872338 as the current OEM replacement.

What It Is

The 872338 is the genuine OEM 90-degree hose connection used at the transom shield on a wide range of Volvo Penta DP, DPX, and SP sterndrive installations. It provides the right-angle connection for the cooling-water hose at the transom, allowing the hose to be routed cleanly without being forced into a tight bend. It supersedes the earlier Volvo Penta 872336 in current parts diagrams. Associated engine packages include AD31/AD41, KAD32 through KAD300, KAMD42 through KAMD300, TAMD31/41/42, TMD31, and selected gasoline packages in the 230, 250, and 740 series.

Compatible Applications

Confirm fitment from the Volvo Penta transom shield cooling-water diagram for the specific drive model and serial number before ordering.

When to Replace

Inspect or replace the hose connection when:

• Cooling water is leaking at or around the connection
• The elbow body is cracked, split, or physically damaged
• Corrosion has attacked the hose-contact or sealing surfaces
• The cooling hose has become loose and will not seat correctly at the connection
• The fitting is being removed during transom shield or cooling-system service
• The connection has deformed and no longer supports the hose at the correct angle

Inspect the adjacent hose, hose clamp, and O-ring (925064) at the same time — a cooling water leak at this fitting location often involves more than one component.

Service Interval

No fixed interval — inspect on condition. 872338 is typically accessed during transom shield service, bellows service, or cooling-system work on DP/DPX/SP sterndrives. Inspect for cracking, corrosion, and hose fit whenever the transom shield is disassembled. Replace any time the fitting shows visible damage, corrosion at the sealing surface, or does not securely retain the cooling-water hose. On older drives with original fittings, proactive replacement during a bellows or transom service is a practical approach.

Installation Notes

• Confirm 872338 is the correct hose connection from the Volvo Penta transom shield cooling-water diagram for the specific drive model and serial number — if the diagram shows 872336, order 872338 as the current replacement
• Inspect the mating cooling-water hose for hardening, cracking, or internal collapse before reinstalling — a damaged hose at this connection can cause cooling flow restriction
• Replace the O-ring (925064) whenever the connection is disturbed — do not reuse a compressed or damaged O-ring
• Inspect the hose clamp (853548 or 872531) for corrosion and replace if there is any doubt about its holding capacity
• Ensure the hose is fully and evenly seated on the 90-degree elbow before tightening the clamp — a partially seated hose will leak under operating pressure
• Support the elbow while tightening the clamp so the hose does not twist or torque the fitting in its housing
• Do not overtighten the fitting into the transom housing — follow Volvo Penta torque specifications for the specific transom assembly
• Verify free cooling-water flow and check for leaks after assembly before returning the drive to service

Technical FAQ

Q: My Volvo Penta diagram shows 872336 — can I order 872338?
Yes. 872338 is the current OEM replacement for 872336. If your Volvo Penta parts diagram or catalog references 872336, 872338 is the correct part to order.

Q: Does 872338 fit all Volvo Penta DP drives?
872338 is verified across DP-A through DP-G, multiple DPX variants, and SP-C1, but Volvo Penta uses different hose connections in different positions on the same transom assembly. Confirm from the transom shield cooling-water diagram for the specific drive model and serial number to ensure 872338 is the correct fitting for the exact position being serviced.

Q: Do I need to replace the O-ring and clamp at the same time?
It is recommended. The O-ring (925064) and hose clamp (853548) at this connection are inexpensive parts and should be replaced whenever the hose connection is disturbed. Reusing a compressed O-ring or corroded clamp risks a cooling water leak shortly after service.

Q: What happens if this fitting cracks or leaks?
A leak at the transom shield cooling-water hose connection allows cooling water to escape before it reaches the engine, which can cause overheating if the flow restriction is significant. Any sign of cooling water weeping at this fitting should be addressed promptly to avoid the risk of engine or drive overheating damage.

Parts Desk Insights

The most important detail with 872338 is its exact position — it is the 90-degree elbow at the transom shield cooling-water hose, and it is fitment-specific to the drive family. The most common ordering mistake is customers searching for a generic 90-degree hose elbow rather than confirming from the Volvo Penta transom schematic, which can result in ordering the wrong fitting for the position. Customers who find 872336 in an older diagram should be redirected to 872338 — the supersession is current. When this fitting is being replaced, suggesting the full associated hardware set (O-ring 925064, clamp 853548, adjacent hose from 876632 hose kit) is worth doing while the transom assembly is already apart.
