Common Issues & Recommended Parts

Below are common maintenance scenarios for the Mercury 402, 40 (2 CYL.):

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
Engine Oil / Maintenance Light: 4-stroke engines require regular oil and filter changes. Use marine-grade oil rated for your engine. Change every 100 hours or annually. → Recommended: Oil Filter, Engine Oil
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 402, 40 (2 CYL.) 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
Change engine oil and oil filter (check drain plug washer)
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
Check valve clearance (refer to service manual for specifications)
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.
