What This Piston is Used For
The piston transfers combustion force through the connecting rod to the crankshaft while the piston rings seal combustion pressure and control oil on the cylinder wall.
During a rebuild, the cylinders should be accurately measured for diameter, taper and out-of-round condition before selecting standard or oversize pistons.
Parts to Inspect During Piston Replacement
- Cylinder bore diameter and condition
- Cylinder taper and out-of-round
- Piston-to-wall clearance
- Piston rings and ring end gap
- Connecting rod bearings
- Connecting rod bolts
- Crankshaft main bearings
- Crankshaft journals
- Cylinder head and valves
- Valve stem seals

When to Use a .010 Oversize Piston
A .010 oversize piston can be used when cylinder wear or damage requires machining beyond the standard bore but does not require a full .020 overbore.
The cylinder should be measured for diameter, taper and out-of-round before machining. The finished bore and piston-to-wall clearance should follow the piston manufacturer's specifications.
Parts to Inspect During an Engine Rebuild
- Cylinder diameter and bore condition
- Cylinder taper and out-of-round
- Piston-to-wall clearance
- Piston rings and ring end gap
- Connecting rod condition
- Connecting rod bolts
- Connecting rod bearings
- Crankshaft main bearings
- Crankshaft journals
- Cylinder head and valves
- Valve stem seals
- Oil passages and lubrication system
- Powerhead gaskets and seals

Standard vs. Oversize Ring Selection
| Piston / Bore Size | Ring Option |
|---|---|
| Standard 79mm | 11605 Yamaha OEM Standard Ring Kit |
| .25mm / approximately .010 Oversize | 11606 Yamaha OEM Oversize Ring Kit |
| .50mm / .020 Oversize | Use the ring package specified for the exact .020 oversize piston. |
What Piston Rings Do
Piston rings seal combustion pressure between the piston and cylinder wall, control the amount of engine oil remaining on the cylinder surface, and help transfer piston heat into the cylinder.
Ring size must match the piston and finished cylinder bore. Incorrect ring sizing can prevent proper ring end gap and cylinder sealing.
Check Ring End Gap During Assembly
Always check piston ring end gap in the cylinder during assembly. Ring end gap requirements can vary by engine, piston manufacturer, piston size and intended application.
Follow the appropriate Yamaha, Mercury or piston manufacturer's rebuilding specification for the engine being assembled.

What is Included
This listing is for a Yamaha OEM standard-size piston ring kit. Piston rings are sized for one piston. Verify the quantity required for your complete engine rebuild before ordering.
What Piston Rings Do
Piston rings seal the space between the piston and cylinder wall while allowing the piston to move freely through the cylinder.
The ring package helps contain combustion pressure, control engine oil on the cylinder wall and transfer heat from the piston into the cylinder.
Standard Rings or Oversize Rings?
| Cylinder / Piston Size | Ring Option |
|---|---|
| Standard 79mm | 11605 Standard Yamaha OEM Ring Kit |
| .25mm / approximately .010 Oversize | 11606 Yamaha OEM Oversize Ring Kit |
| .50mm / .020 Oversize | Use the ring package specified for the exact .020 oversize piston being installed. |
Check Ring End Gap During Assembly
Piston ring end gap should be checked in the cylinder during engine assembly. Ring specifications can vary based on piston manufacturer, bore size and engine application.
Follow the Yamaha, Mercury, Wiseco or Vertex specifications applicable to the piston and engine being assembled.
