Common Issues & Recommended Parts
Below are common maintenance scenarios for the Mercury 25 Jet (2 CYL.)(2-STROKE)(International):
-
Water Pump / Overheating: If the tell-tale stream is weak or absent, the water pump impeller likely needs replacement. Inspect annually or every 100 hours. → Recommended: Water Pump Impeller Kit
-
Fuel System Issues / Hard Starting: Stale fuel and ethanol-related deposits are common in 2-stroke carbureted engines. Clean or rebuild carburetors and replace fuel lines if deteriorated. → Recommended: Carburetor Repair Kit, Fuel Line Assembly
-
Spark Plug Fouling: 2-stroke engines are prone to spark plug fouling from oil residue, especially at low RPM. Replace plugs at each annual service. → Recommended: OEM Spark Plugs
-
Gear Case Oil Leak: Check lower unit seals if gear oil appears milky (water contamination). Replace seals and gaskets during lower unit service. → Recommended: Lower Unit Seal Kit, Drain Plug Gaskets
-
Thermostat Failure: A stuck thermostat can cause overheating or poor warm-up. Replace if operating temperature is inconsistent. → Recommended: Thermostat Assembly

100-Hour / Annual Service Checklist
Regular maintenance keeps your Mercury 25 Jet (2 CYL.)(2-STROKE)(International) running reliably season after season. Most of these tasks can be performed with basic tools and the factory service manual.
- Replace water pump impeller and inspect wear plate
- Inspect and clean carburetor(s); check fuel mixture settings
- Replace spark plugs and check ignition timing
- Drain and refill lower unit gear oil; inspect for water contamination
- Inspect fuel lines, primer bulb, and fuel filter for deterioration
- Check and replace sacrificial anodes (zinc or aluminum)
- Inspect propeller for damage; check shaft seal and cotter pin
- Decarbonize exhaust ports and piston crown if needed
- Lubricate all grease points (steering, tilt tube, shift linkage)
- Inspect control cables and throttle/shift linkage for smooth operation
-
Pro Tip: Always flush the engine with fresh water after saltwater use — even a quick 10-minute flush significantly extends component life.
-
Pro Tip: Use fuel stabilizer in the tank before winter storage, and fog the cylinders to prevent internal corrosion during extended periods of non-use.
