Wiseco Yamaha 4-Stroke .020 Oversize Piston Kit
Yamaha F75, F80, F90 & F100 Wiseco .020 Oversize Piston Kit - 79.5mm - 3208P2
The Wiseco 3208P2 Piston Kit is a .020 oversize / 79.5mm piston for select Yamaha four-cylinder four-stroke outboards including F75, F80, F90 and F100 applications.
This piston is intended for engine rebuilds where the cylinder has been machined beyond the standard 79.00mm bore and finished for the 79.5mm oversize piston.
Verified engine families include select 1999-2003 Yamaha F80 and F100 applications along with select 2005 and later F75 and F90 four-stroke outboards.
This is NOT a standard-size piston.
The cylinder must be properly measured and machined for a 79.5mm / .020 oversize piston before installation.
Do not install this piston in a standard 79.00mm bore.

Oversize piston selection should be based on actual cylinder measurements. The cylinder should be bored and finished to the correct clearance for the Wiseco piston being installed.
Do not choose an oversize piston simply because the original piston or cylinder shows wear.
Standard 79mm Wiseco Piston Option
If the cylinder remains within standard-size service limits, use the standard 79.00mm Wiseco 3208PS piston instead.
Wiseco Standard Piston Kit - 79.00mm - 3208PS
Standard-size piston for compatible Yamaha F75, F80, F90 and F100 four-stroke engines where the cylinder remains suitable for a 79.00mm standard 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 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
- Oil passages and lubrication system
- Powerhead gaskets and seals
