    I need to replace the air filter on my M-18, and I can't find one on any Web site.
    Does anyone know where I can buy one or, ev en better, buy material suitable for making one?
    Thanks to anyone who can help.

    Are you referring to the foam silencer?
    Part no 300429 from your local Westerbeke dealer. You can buy any part online at the Westerbeke website.

    Or go to NAPA and match the size up with their small engine parts. I have the NAPA p/n for the M25 etc, but not the M18.
    Or visit your local well-stocked lawn/garden/tractor/mower dealer. Or check at Tractor Supply.
    If you find a larger one you can trim it and tack the ends together w/ contact cement.

    A boat is generally a really clean environment, and usually a metal screen is sufficient, mostly to prevent the engine from sucking-in some foreign object that would damage it. The air is generally dust free.

    Try Toad for a replacement

    or measure your intake diameter and replace it with a K&N filter - the look and work better than the foam.

    Air Filter ( Element / Cleaner )
    Part #300429 from Universal

    This genuine Universal air filter / element works on the following Universal engines: M12, M2-12, M-15, 5411, M-18, M3-20, M-30 and M4-30

    Our price: $16.60 - each​

    My opinion, do without. If you must, and cost is an issue, it looks just like the foam sleeves used on lawn mowers.

    If you replace with a K&N "something" you will probably have to give up the silencer; bad idea.
