Water in Fuel - Mercury Optimax
Heading back from Gsy to Jsy today, and my Merc Opti 225 started wavering on the revs in a big swell. Then an audio alert sounded, and the display showed 'water in fuel'. I limped home at 20 knts, and then drained the seperator, but only fuel came out of the seperator.
After re-starting the engine, the same alert came up. What should I do next? Haven't got a clue about engines generally, so sorry if this is blindingly obvious, but thanks in advance for any help!
