What This Elbow Does
This genuine Mercury Marine / Quicksilver 90-degree elbow connects the oil hose to the cylinder block in select MerCruiser oil cooler systems. It maintains the correct hose routing angle and OEM connection geometry for the oil-cooling circuit. This is not a generic 90-degree fitting — the correct elbow depends on the specific oil cooler layout, hose routing, and diagram position for your engine serial number. Using a generic substitute risks incorrect hose alignment, fitting interference, or oil leaks in the cooling circuit.
Compatible Applications
Fitment is by oil cooler / flywheel housing diagram, not engine displacement alone. Confirm against your MerCruiser parts diagram and engine serial number before ordering.

Serial Number Fitment Notice
Oil hose elbows vary by angle, thread type, hose routing, and cooler layout across MerCruiser families. The correct match is always the diagram callout confirmed by engine serial number — not engine size or displacement alone.
When to Replace This Elbow
Replace if the elbow is corroded, cracked, leaking at the hose connection, seized onto the block fitting, or damaged during removal. Also inspect during any oil cooler, flywheel housing, or oil hose service if surrounding fittings or hoses show signs of age or leakage.
Service Interval
Inspect at every oil cooler or flywheel housing service. Replace on condition — any cracking, corrosion, or oil weeping at the elbow joint warrants immediate replacement.

Installation Notes
- Confirm the correct oil cooler diagram location before installation — do not fit by appearance alone.
- Inspect the oil hose, clamps, cylinder block fitting, cooler fittings, and nearby hardware before reassembly.
- Use the correct thread sealant where specified in the MerCruiser service manual.
- Avoid overtightening threaded fittings into cast block or housing components.
- Replace the connected oil hose and clamps if they show age, cracking, or oil residue.

Parts Desk Insights
The most common issue with this part is customers treating it like an off-the-shelf 90-degree fitting. On MerCruiser oil cooler circuits, the elbow design is matched to the specific hose routing and diagram position — a generic fitting with the same angle may not clear adjacent components or connect cleanly to the block. If the original elbow is seized or corroded, soak it before removal to avoid damaging the block or cooler threads. Always replace the connected hose and clamps at the same time if there is any oil residue or age cracking present.
Technical FAQ
Q: Can I use a generic 90-degree elbow from a hardware store?
Not recommended. The OEM elbow is matched to the specific thread, hose size, and routing geometry of your MerCruiser oil cooler circuit. A generic fitting risks misalignment, thread mismatch, or oil leaks.
Q: How do I confirm this is the right elbow for my engine?
Use your MerCruiser engine serial number to pull the flywheel housing or oil cooler parts diagram and confirm 48246 / 22-48246 is called out at the hose-to-block connection position.
Q: Should I replace the oil hose at the same time?
Yes, if the hose shows any cracking, oil residue, or stiffness. With the fitting disconnected, replacement is straightforward and avoids a repeat service.
