What This O-Ring Does
The fuel filter bowl O-ring forms the primary seal between the removable fuel filter bowl and the fuel filter housing. Maintaining a proper seal helps prevent fuel leaks and keeps unwanted air from entering the fuel system.
Because fuel system seals are exposed to gasoline, ethanol blends, vibration, and age, replacement is recommended whenever the bowl is removed and the seal shows signs of wear.

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.

What This Part is Used For
The intake valve stem seal fits around the intake valve stem and helps regulate the amount of engine oil that passes between the valve stem and valve guide.
The valve guide requires lubrication, but excessive oil entering past the guide can reach the intake port and combustion chamber. The valve stem seal helps control this oil flow while allowing the valve to move normally.
Why Intake Valve Stem Seals Matter
Valve stem seals operate in a high-temperature environment and can become hardened, worn or damaged over time. A deteriorated seal may allow excess oil into the combustion chamber.
During a cylinder-head rebuild, replacing valve stem seals while the valves are already removed can prevent having to disassemble the valve train again later.
When to Replace Valve Stem Seals
- During a complete cylinder-head rebuild
- When replacing intake or exhaust valves
- When servicing valve guides
- If seals are hardened, cracked, flattened or damaged
- When excessive oil usage is traced to the cylinder head
- After overheating or cylinder-head damage
- During a complete powerhead overhaul

What This Part is Used For
The exhaust valve stem seal fits around the exhaust valve stem and helps control the amount of engine oil passing between the valve stem and valve guide.
The exhaust valve operates in a particularly high-temperature area of the cylinder head. The valve stem seal must provide controlled lubrication to the valve stem and guide while limiting excessive engine oil from entering the exhaust port or combustion chamber.
Why Exhaust Valve Stem Seals Matter
Valve stem seals are exposed to repeated heat cycles and can harden, deteriorate or become damaged over time. A worn seal may allow excessive oil to travel past the valve guide.
During a cylinder-head rebuild, replacing worn valve seals while the valve train is already disassembled can help prevent future oil-control issues and avoid additional cylinder-head disassembly.
When to Replace Exhaust Valve Stem Seals
- During a complete cylinder-head rebuild
- When replacing exhaust valves
- When servicing valve guides
- If the existing seal is hardened, cracked or damaged
- When excessive oil consumption is traced to the cylinder head
- After engine overheating or valve-train damage
- During a complete powerhead overhaul

What This Part is Used For
The exhaust valve opens during the engine's exhaust stroke to allow combustion gases to leave the cylinder. It then closes against the valve seat so the cylinder can seal during the next compression and combustion cycle.
Exhaust valves operate in one of the hottest areas of the cylinder head, making correct valve condition, valve-seat contact and valve-guide clearance especially important.
When Should an Exhaust Valve Be Replaced?
Exhaust valves should be inspected whenever the cylinder head is removed or rebuilt. A burned, bent, worn or damaged exhaust valve can prevent the cylinder from sealing correctly and contribute to poor compression and engine performance.
Always inspect the valve seat, guide and stem seal when replacing the exhaust valve.
Common Reasons for Exhaust Valve Replacement
- Burned or damaged valve face
- Bent valve stem
- Piston-to-valve contact
- Excessive valve stem wear
- Corrosion or pitting
- Valve face no longer sealing correctly
- Low cylinder compression caused by valve leakage
- Cylinder-head rebuilding
- Complete powerhead overhaul
Inspect These Parts During Exhaust Valve Replacement
- Exhaust valve seat
- Exhaust valve guide clearance
- Exhaust valve stem seal
- Intake valve and intake valve stem seal
- Valve spring
- Valve retainer and keepers
- Camshaft lobes and journals
- Cylinder-head sealing surface

What This Part is Used For
The intake valve opens during the engine's intake cycle to allow the air / fuel charge to enter the combustion chamber. The valve then closes against its seat so the cylinder can seal during compression and combustion.
Proper valve sealing is critical to cylinder compression, combustion efficiency and overall engine performance.
When Should an Intake Valve Be Replaced?
Intake valves should be carefully inspected whenever the cylinder head is removed or rebuilt. A damaged valve may not seal correctly against the valve seat and can contribute to low compression or poor engine performance.
Valve condition should be evaluated together with the valve guide and valve seat rather than replacing the valve alone without inspecting the mating components.
Common Reasons for Intake Valve Replacement
- Bent valve stem
- Valve-to-piston contact
- Damaged or burned valve face
- Excessive valve stem wear
- Corrosion or pitting
- Valve face no longer sealing correctly
- Cylinder-head rebuild
- Major powerhead overhaul
Inspect These Parts During Valve Replacement
- Valve seat condition
- Valve guide clearance
- Intake valve stem seal
- Exhaust valve and exhaust valve stem seal
- Valve spring condition
- Valve retainers and keepers
- Camshaft lobes
- Camshaft journals
- Cylinder-head sealing surface
