Hi,
i am replacing my inline engine raw water filter with a new "basket" style unit.

The in line unit was below the water line, which was a bit of a hastle. Even if I shut the through hull before cleaning water goes everywhere when the pipes drain. Forget to shut the through hull and water goes everywhere until my rather slow brain kicks into gear and works out what has happened.

So, at what height should the filter be located? I am thinking of locating with the lid about 20 mm above the water line. Logic being that I want to minimise the water released when opening, but do not want it high enough to mean that the pipes drain and fill with air when opened for cleaning.

Does this make sense?

thanks
