    The other problem you might get is water in the fuel. Purging a water trap below the filter is an easy fix, but again, the water needs to be removed from the tank.

    T link belt. If your alternator bearing fails it will cease to rotate and so will your engine water circulation pump.

    It was crud in the tank that had been shaken up by a very bumpy trip through the typical F7 Solent chop. The tank only had a couple of gallons left, so that allowed it to slosh around. Unfortunately, fuel tank removal on a Snapdragon 24 starts with an angle grinder and goes downhill from there and the only access is the filler cap, so the crud is still there, but I don't let the tank go below about half full, so the fuel can't slosh around.

    I agree that the solution is to get rid of the crud/bug, but one tends only to discover there's a problem when the filter blocks, which is, almost by definition, never at a convenient time or suitable sea state. In such a situation, an easy short-term solution can save an awful lot of grief, maybe even lives.

    I've got one that I use for oil changes. I know I really ought to try and clean the tank, but I'm a great believer in letting sleeping dogs lie (translation: I'm an idle git) Still, since the boat's out of the water for the summer so I can do all the stuff I couldn't do during the winter because I was ill, I really ought to add it to the list.

    OTOH, I hadn't had a problem in spite of not changing a filter for 10 years...

    Thing is.....we own boats and just really waiting for the next thing to go wrong aren't we? I also hadn't changed the primary filter on my 3GM some years ago and when I did little crud was showing. A year or two later we ground to a halt with the "bug". Can't do without cable ties and duck tape...........and hammer and wood saw of course.

    Plus a few bits of wood. BTW, has anyone mentioned suitably sized wooden plugs tied on next to each through hull? Of course, none of these are engine spares but, as with all spares, you'll only need 'em if you haven't got 'em, just like the selection of split pins and stuff that's gathering dust in my junk locker

    I used a tapered wood bung for the first time recently - finally justifying buying then many years ago. Arrived at boat and soon noticed no cooling water from the exhaust, fortunately I was on the way to the pontoon from my mooring so only needed to travel a couple of hundred meters. Investigations revealed that turning the sea-cock handle actually had no effect on the ball within. Changing for a new one (something else that has been cluttering up the bosun's locker for years) was a relatively painless task with the use of the wooden bung.

    I also carry flexible and solid fuel pipes plus olives.
    I've also had a starter motor fail, but a strip and clean solved that.
    I had a water pump bearing break down in a matter of hours from no drops to water pouring out. Bought a new pump and had the old one refurbished to keep as a spare.

    After getting the bearing fixed the pump went back into service. The new one is my spare, I had to get a new bracket made for it, as the old model had been superceded and the new fitting was different.
