Advanced Sleeve Yamaha Inline 4-Cylinder Replacement Sleeve
Yamaha Inline 4-Cylinder 4-Stroke Cylinder Sleeve - Advanced Sleeve 1185SC
The Advanced Sleeve 1185SC is an aftermarket replacement cylinder sleeve for compatible Yamaha inline 4-cylinder four-stroke outboard engines.
This straight cylinder sleeve has a 3.310" outside diameter, 3.118" bore, and 5.195" overall length.
Pro Marine also stocks the 1185SA version, which uses the same 3.118" bore and 5.195" length but has a smaller 3.270" outside diameter.
The key difference between the 1185SC and 1185SA sleeves is the outside diameter.
1185SC = 3.310" OD
1185SA = 3.270" OD

Yamaha Inline 4-Cylinder Application
The Advanced Sleeve 1185SC is designed for compatible Yamaha inline 4-cylinder four-stroke powerheads.
Cylinder sleeves are typically used during major powerhead rebuilding when the original cylinder wall is too worn, scored, corroded, damaged, or previously machined beyond the point where a normal oversize piston repair is practical.
The 1185SC uses the larger 3.310" outside diameter.
Do not select a cylinder sleeve only by horsepower or piston bore size. The engine block must be measured to determine the required sleeve outside diameter and machining dimensions.
If the block requires the smaller 3.270" OD, use the 1185SA sleeve linked below.

What a Replacement Cylinder Sleeve Does
A replacement cylinder sleeve restores the cylinder wall when the original bore is no longer suitable for normal rebuilding. The damaged cylinder area is machined to accept the replacement sleeve, allowing the block to be repaired instead of discarded.
Once installed, the sleeve is bored and honed to the correct finished size for the piston that will be used in the rebuilt engine.
When the 3.310" OD Sleeve May Be Used
The larger outside diameter of the 1185SC provides additional material for applications where the block has been machined larger, has suffered more extensive cylinder-wall damage, or requires the larger sleeve outside diameter during the repair process.
The machine shop should determine which sleeve outside diameter is appropriate after inspecting and measuring the block.
Common Reasons to Install a Cylinder Sleeve
- Deep piston or cylinder-wall scoring
- Broken piston or piston-ring damage
- Severe cylinder corrosion
- Excessive cylinder taper
- Excessive out-of-round condition
- Damage beyond available oversize piston dimensions
- Previously bored cylinder requiring restoration
- Major Yamaha powerhead rebuilding
Machine Shop Installation
Cylinder sleeve installation requires precision machining. The engine block must be measured and machined for the correct sleeve fit before installation.
After the sleeve is installed, the cylinder must be bored and honed to the proper finished dimension and piston-to-wall clearance for the piston being installed.
Standard or Oversize Piston After Sleeving?
One advantage of installing a replacement sleeve is that the machinist can finish the repaired cylinder for the piston size selected for the rebuild.
Depending on the engine, piston availability and condition of the remaining cylinders, the sleeved cylinder may be finished for a standard or compatible oversize piston.
Parts to Inspect During a Cylinder Sleeve Repair
- Pistons and piston size
- Piston rings
- Finished cylinder bore
- Piston-to-wall clearance
- Connecting rods
- Connecting rod bolts
- Connecting rod bearings
- Crankshaft main bearings
- Crankshaft journals
- Cylinder head and sealing surface
- Valves and valve stem seals
- Powerhead gaskets and seals

What a Replacement Cylinder Sleeve Does
A cylinder sleeve restores the cylinder wall when the original bore cannot be reused or machined successfully. The damaged original cylinder area is machined to accept the replacement sleeve, and the sleeve is then installed and finished to the required piston bore and clearance.
Sleeving can allow an otherwise damaged engine block to be returned to service when a standard or oversize piston repair is no longer practical.
When a Cylinder Sleeve May Be Needed
- Deep cylinder-wall scoring
- Severe piston or ring damage
- Corrosion or pitting in the cylinder wall
- Previous cylinder machining beyond available piston sizes
- Excessive taper or out-of-round
- Localized cylinder-wall damage
- Restoring a damaged block during a complete powerhead rebuild
Machine Shop Installation
Cylinder sleeve installation requires precision block machining. The block should be measured before selecting the sleeve so the correct outside diameter and required interference fit can be determined.
After installation, the replacement sleeve must be bored and honed to the correct finished dimension for the piston being installed.
Parts to Inspect During a Sleeved Powerhead Rebuild

This listing is for the Wiseco 3208PS standard-size piston kit. Confirm the exact kit contents shown on the product listing before ordering any additional rings, pins, clips or related components separately.
What This Piston is Used For
The piston transfers combustion force through the connecting rod to the crankshaft. It must maintain the correct clearance within the cylinder bore while supporting the piston rings that seal combustion pressure and control engine oil.
During a powerhead rebuild, piston selection should be based on the actual finished cylinder-bore measurement rather than simply replacing the original piston with the same nominal size.
Standard Piston or Oversize Piston?
| Cylinder Condition | Typical Piston Choice |
|---|---|
| Bore remains within standard-size service limits | Wiseco 3208PS 79.00mm standard-size piston |
| Cylinder must be bored .020 oversize | Wiseco 3208P2 79.5mm / .020 oversize piston |

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.
