Introduction
The Mercury Precision Crankcase Oil Pump (Model 802889A 1) is an essential tool for maintaining marine engines. This original equipment oil drain pump is specifically designed for Mercruiser sterndrive and inboard marine engines that feature threaded dipstick tubes. It provides a clean and efficient method for extracting used engine oil, simplifying routine oil changes. The pump includes an outlet/discharge hose for convenient oil collection.
Safety Information
- Always wear appropriate personal protective equipment, including gloves and eye protection, when handling engine oil.
- Ensure the engine is cool before attempting to drain oil to prevent burns.
- Dispose of used engine oil responsibly according to local environmental regulations. Do not pour oil down drains or onto the ground.
- Keep the work area well-ventilated to avoid inhaling oil fumes.
- Keep out of reach of children and pets.

Setup
- Prepare the Engine: Ensure the marine engine is slightly warm (not hot) to allow the oil to flow more easily. Running the engine for a few minutes can help, but allow it to cool down sufficiently to be safe to touch.
- Locate Dipstick Tube: Identify the threaded dipstick tube on your Mercruiser sterndrive or inboard marine engine.
- Remove Dipstick: Carefully remove the engine's dipstick.
- Attach Pump: Thread the brass fitting of the oil pump onto the threaded dipstick tube. Ensure it is securely tightened to prevent air leaks during operation.
- Connect Discharge Hose: Attach the provided outlet/discharge hose to the pump's outlet port.
- Position Collection Container: Place a suitable, empty container (e.g., an old oil jug or drain pan) to collect the used oil. Ensure the discharge hose is securely positioned within the container to prevent spills.
Operating Instructions
Follow these steps to effectively drain oil from your marine engine:
- Initiate Pumping: Begin pumping the handle of the oil drain pump. A few initial strokes may be required to establish suction.
- Maintain Suction: Continue to pump the handle steadily. The pump works by creating a vacuum to draw oil up through the dipstick tube and out through the discharge hose.
- Monitor Oil Flow: Observe the flow of oil into your collection container. The flow may be intermittent, especially as the oil level in the engine decreases.
- Complete Drainage: Continue pumping until no more oil is extracted from the engine. This may take some time depending on the engine size and oil viscosity.
- Remove Pump: Once drainage is complete, unthread the pump from the dipstick tube. Be prepared for any residual oil in the pump or hose.
- Replace Dipstick: Reinsert the engine's dipstick.
Maintenance
- Cleaning: After each use, clean the pump and hose thoroughly. You can flush it with a small amount of clean oil or a suitable cleaning solution to remove residual dirty oil.
- Drying: Ensure the pump and hose are completely dry before storage to prevent corrosion.
- Storage: Store the oil pump in a clean, dry place, away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect the pump for any signs of wear, damage, or leaks, especially around the seals and connections. Replace if necessary.
