Though it’s not a widely known fact, it is possible to use an automobile oil filter in your outboard engine. Marinas and outboard motor manufacturers will suggest the use specialized outboard oil filters, however these are often more expensive, and unnecessary. If your engine uses standard two cycle outboard oil, just find an automotive filter that has the same thread and diameter. Installing it is the same as you would expect from a filter, but remember to rub a small amount of oil on the bottom of the filter before installation, as this will help to lubricate it and prevent it from sticking.
It’s also best to avoid filters with Teflon built in, or a Teflon additive. Oil filters also have an expiration date, so ensure you don’t go beyond the date or you will risk having a broken filter and engine problems.
