Step 2: Prepare the Yacht

Step 3: Locate the Oil Drain Plug

Consult your yacht’s owner’s manual to find the location of the oil drain plug. It is usually located at the bottom of the engine oil pan. Place the oil drain pan beneath the drain plug to catch the old oil.

Step 4: Drain the Old Oil

Using the appropriate wrench, carefully loosen and remove the drain plug. Allow the old oil to drain completely into the pan. Once the oil has stopped flowing, replace and tighten the drain plug securely.

Step 5: Replace the Oil Filter

The oil filter can usually be found adjacent to the oil pan. Using the correct wrench, loosen and remove the old oil filter. Take care not to spill any remaining oil in the process. Before installing the new oil filter, lubricate its rubber gasket with some fresh oil. Then, hand-tighten the new filter into place.

Step 6: Add New Oil

Refer to your owner’s manual to determine the correct oil type and quantity for your yacht’s engine. Use a funnel to pour the new oil into the oil filler hole. Once you’ve added the appropriate amount, replace the oil filler cap securely.

Step 7: Check for Leaks

Before starting the engine, inspect the drain plug and oil filter for any signs of leakage. If everything looks secure, you are ready to move on.

Step 8: Start the Engine

Start the engine and let it run for a few minutes, allowing the fresh oil to circulate throughout the system. Check the oil level using the dipstick, and add more oil if necessary to bring it to the recommended level.

While the process itself is relatively straightforward, it requires attention to detail and adherence to safety guidelines. If you feel uncertain or inexperienced in performing an oil change, it is always best to seek professional help from trained yacht maintenance companies like CF Boatworks.
