What This Part is Used For
The air filter is installed in the engine's Integrated Air Fuel Module and helps filter incoming air before it enters the engine.
Clean, unrestricted airflow is important for proper combustion, fuel efficiency and engine performance. The filter screen helps keep dirt, debris and other contamination from entering the intake system.
Why Air Filter Condition Matters
Over time, the air filter can become dirty, restricted, damaged or deteriorated from normal engine operation and environmental exposure.
A restricted or damaged filter may interfere with proper airflow and can contribute to:
- Reduced airflow into the engine
- Poor or inconsistent engine performance
- Reduced fuel efficiency
- Dirty intake components
- Air filter material deterioration
Air filters are often overlooked compared with oil filters, fuel filters and spark plugs.
Inspect the filter periodically and replace it if the filter material is dirty, damaged, deteriorated or restricting airflow.
Where is the Air Filter Located?
On these Mercury 75-115 HP EFI FourStroke engines, the filter is shown in the Integrated Air Fuel Module parts diagram.
Mercury identifies the air filter as a single filter per assembly. The older 897575T01 and 897575T02 numbers were superseded by current Mercury OEM part number 8M0082911.

Common Symptoms of a Failed Head Gasket
A damaged cylinder head gasket can allow combustion pressure, cooling water, or engine oil to leak between engine passages.
Symptoms depend on the location and severity of the gasket failure. The following conditions may indicate a head gasket problem.
- Loss of engine compression
- Engine overheating
- Cooling water entering a combustion chamber
- Water contamination in engine oil
- Unexplained loss of engine power
- Rough running or misfiring
- Difficulty starting
- Combustion gases entering the cooling system
- Visible gasket damage during cylinder head removal
These symptoms can also be caused by other engine problems. Perform appropriate diagnostic testing before concluding that the cylinder head gasket requires replacement.

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
