Thanks to Rodbolt I am now aware that I may have water in the water trap in my 93 115 Yammy. I have unbolted it from the engine however getting the tranparent plastic base of the head of the filter is proving difficult - does it just unscrew anti-clockwise (ie might have to use CRC or similar to assist)? I have a proper fuel filter and trap in the boat so I might remove it altogether.
