Wiseco Yamaha / Mercury 4-Stroke .020 Oversize Piston Kit
Yamaha F90-F115 & Mercury 115 EFI Wiseco .020 Oversize Piston Kit - 79.5mm - 3207P2
The Wiseco 3207P2 Piston Kit is a .020 oversize / 79.5mm 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-strokes through serial 1B366822.
This piston belongs to the same engine family as Yamaha 60C-W1164 and 68V-W1164 piston assemblies and Mercury 880895 piston assemblies.
This is NOT a standard-size piston.
The cylinder must be properly measured, machined and finished for the 79.5mm / .020 oversize Wiseco piston before installation.
Do not install this piston into a standard 79.00mm bore.

Shop Yamaha 90HP Rebuild PartsWhen to Use an Oversize Piston
An oversize piston is used when cylinder wear, taper, scoring or damage requires the cylinder to be machined larger than the original standard bore.
The cylinder should first be accurately measured to determine whether it can remain standard, be bored .010 or .020 oversize, or requires installation of a replacement cylinder sleeve.
Parts to Inspect During an Oversize Piston Rebuild
- Cylinder bore diameter
- Cylinder taper and out-of-round
- Finished 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

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 powerhead rebuild, piston size should be selected only after the cylinders have been accurately measured for diameter, taper and out-of-round condition.
Parts to Inspect During a Piston Replacement
- Cylinder bore diameter, taper and roundness
- Piston-to-cylinder-wall clearance
- Piston rings and ring end gap
- Connecting rods and rod bolts
- Connecting rod bearings
- Crankshaft main bearings
- Crankshaft journals
