Boat Servicing Instructions For Submerged Motors

Sometimes, your outboard motor might be accidentally submerged in the body of water that you are traveling in. This is often the result of forgetting to attach the chain on the motor’s bracket to the boat or to check the mounting bolts that are responsible for holding everything in place. With the following boat servicing instructions on hand, you will be able to effectively look after a motor that has been accidentally submerged.

Step 1: Remove the engine cover and wash away any debris using a pressure washer. If there is sand, silt or another gritty material present, you will need to completely disassemble and inspect the power head.

Step 2: Unplug each of the spark plugs by taking hold of a cap (not the wire) and twisting whilst pulling upwards. You can then remove the plugs themselves with a spark plug wrench.

Step 3: Disconnect the fuel supply lines, then drain and clean them (or replace if they are damaged). If the motor has an attached fuel tank you will need to inspect it for contamination and drain if necessary.

Step 4: Place the motor in a horizontal position with the spark plug ports facing downwards. This will allow any water inside to drain away. You can then force out any remaining water by slowly rotating the flywheel.

Step 5: Return the motor to its standard upright position. Check the gear case oil for contamination by opening the oil pan, draining out about a teaspoon of oil and inspecting it for a milky colouration.

Step 6: Disconnect all of the external electrical components and disassemble them for cleaning. Spray each of the connectors with an electrical contact cleaner and a small amount of dielectric grease to prevent corrosion.

Before you return the motor to your vessel, the last boat servicing step that you must complete is a test. Try to start and run the motor for around half an hour; if it won’t start, the tips of the spark plugs may still have moisture present. Using compressed air can help to dry them out, but if your vessel still refuses to start you will need to take it into a dealer for professional boat servicing and cross your fingers in hopes for the best.
