After getting a few pm’s thought that I would just post this. Not actually thought of a price for them, but would have to be in the region of £20( pm if interested) or you could make your own.
First you take your pump and cut off the silly mounting lugs on the side and trim the filter to a nice flat top about ¾” deep. Next a sheet of prelayed glass about 6oz and big enough to bridge the vee of the hull leaving about 1” clearance for the filter, drill a hole in the centre to be a nice snug fit on the bottom of the pump pace the pump in the hole and glass around it. Trim and tidy stick the filter to the underside with sikaflex or similar and glue to the bottom of the boat. Stick yer pump in the hole and secure with a ss jubilee clip or bungee over the top.
You can still get the pump out to take the hair out of it and unclog the filter, but kick it and you’ll hurt your toe.
