Vertex Yamaha / Mercury 4-Stroke .010 Oversize Piston Kit
Yamaha F90-F115 & Mercury 115 EFI Vertex .010 Oversize Piston Kit - 24228025
The Vertex 24228025 Piston Kit is a .010 oversize / .25mm oversize piston for select Yamaha four-stroke and Mercury 115HP EFI outboards.
Verified engine families include extensive Yamaha F115 and LF115 applications, select Yamaha F75 and F90 engines, and select Mercury 115HP EFI four-stroke outboards.
This piston is part of the same engine family as the Yamaha 60C-W1164 and 68V-W1164 piston assemblies and Mercury 880895 piston assemblies.
This is NOT a standard-size piston.
The cylinder must be measured and properly machined for the .010 / .25mm oversize piston before installation.
Do not install this piston into a standard 79.00mm bore.

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

What the Connecting Rod Bolt Does
Connecting rod bolts secure the connecting rod cap to the connecting rod. The assembly surrounds the crankshaft journal and must remain securely clamped while the piston and rod repeatedly change direction at engine speed.
Rod bolts are highly stressed engine fasteners. Correct bolt condition, installation procedure and tightening specification are critical during a powerhead rebuild.
Why Inspect or Replace Connecting Rod Bolts During a Rebuild?
Connecting rod bolts are subjected to repeated tensile loading every time the engine operates. During a powerhead rebuild, inspect the bolts and connecting rod assembly carefully for damage, thread problems, corrosion, stretching or other signs that could compromise clamping force.
Follow the applicable Yamaha or Mercury service procedure for the exact engine being assembled. Torque specifications and whether a fastener should be reused can vary by engine family.
