How to change oil on outboard boat motor

Without oil, nothing works. This is a safety test that applies to all internal combustion engines, and therefore also for boat drives where lubricants and filters are to be changed regularly. How often? Engine manufacturer Volvo Penta recommends, for example, to exchange engine oil and filters after approximately 50 or 100 operating hours, or at least once a year, either during an inward or outward.

Oil change

As simple as with the car, where the waste oil trickles down from the oil pan after removing the drain plug, this does not work on a boat, of course. Except in the case of large diesel units with built-in suction pump, the boat owner himself has to go, armed with a specially designed hand or electropop, a correspondingly large collecting tank. Make sure that you have enough towels at hand, and absorbing agents such as an oil-filled cushion and also a collecting bowl. This helps to avoid or eliminate stains before they become an environmental problem when they are pumped overboard together with the bilge water and pollute the water. Vacuum pumps with integrated collection tank are also very practical.

It is best to run the engine warm because warm oil is fluid and can be pumped more easily. After the shut-off, the extraction probe is inserted into the opening of the oil dipstick until it touches the seat of the oil pan. The correct length of the probe can already be determined using the oil dipstick. In the case of an emergency, the plastic pipe can be improvised. Before you start, however, you can determine whether the hose connections are secure and the collecting container is secure.
Even if you do not necessarily have to use the oil recommended by the manufacturer, it is important to pay heed to the correct viscosity and the API classification. If in doubt, please take a look at the manual or in the operating manual of the engine manufacturer.

If enough new oil has flowed into the engine and the oil dipstick shows maximum level, clean it all and seal it. Then begin the engine and let it warm up to control two things: the oil lamp on the dashboard, which should go out after a few seconds and no oil drips on the filter. After shutting down, check the oil level again and, if necessary, add some oil.
Please dispose of the old oil and the used filter at a waste oil collecting point. These facilities, if they are not available in the marina, can be found in municipalities, municipalities or recycling centers.

Filter change

When purchasing the replacement filter, it is recommended to use the products recommended by the manufacturer to achieve optimum efficiency. If there are problems when you remove the old filter (such as a too tight), there are all sorts of rustic methods that you should take away, instead, get the right spanner to clean the old filter. Before placing the new filter, make sure that the gasket is seated properly and coated with some oil. If the filter is to be loosened a little while it is replaced, screw it tightly without tools.
