The deck water filler cap - blue plastic has broken. It has the brand name Len but I am unable to find a new one having this brand. I did buy a replacement cap which looked the same but did not screw down. Any suggestions - I don't want to change the filler assembly - its too awkward to get to the plastic pipe under the deck
You didn't mention year and model of your boat. This one fit our 2000/2001 boat: https://www.asap-supplies.com/eu/water-deck-filler-cap-305510
I got my replacement here

Here the original Bavaria spare.
As expected the price is pretty high
