  • Fuel Injector Issues (EFI models): Rough idle or misfires may indicate clogged fuel injectors. Use fuel stabilizer and clean injectors periodically. → Recommended: Fuel Injector, Fuel Filter
  • 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
  • Anode Corrosion: Inspect sacrificial anodes regularly, especially in saltwater. Replace when 50% depleted to protect against galvanic corrosion. → Recommended: Zinc/Aluminum Anode Kit

100-Hour / Annual Service Checklist

Regular maintenance keeps your Mercury 45 BODENSEE (4-STROKE) running reliably season after season. Most of these tasks can be performed with basic tools and the factory service manual.

  1. Replace water pump impeller and inspect wear plate
  2. Change engine oil and oil filter (check drain plug washer)
  3. Replace spark plugs and check ignition timing
  4. Drain and refill lower unit gear oil; inspect for water contamination
  5. Inspect fuel lines, primer bulb, and fuel filter for deterioration
  6. Check and replace sacrificial anodes (zinc or aluminum)
  7. Inspect propeller for damage; check shaft seal and cotter pin
  8. Check valve clearance (refer to service manual for specifications)
  9. Lubricate all grease points (steering, tilt tube, shift linkage)
  10. 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.
