Water in Fuel - Mercury Optimax

[FreeTrader]

Hi all,

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!

I have no idea about outboards but my experience of the water-in-fuel sensor in Td5 Land Rovers is that the sole function of the warning light is to indicate a defective sensor... worth popping a new one in to see if it is that perhaps?

Interesting; This just came up on a boating/fishing forum in the US.

SUBJECT: 200 Optimax, water in fuel alarm
The water in fuel alarm is going off no water in racors and drained filter on engine no water in either. alarm comes on most of the time but sometimes upon restart it doesn't for a while.
I have unplugged the wire from the bottom of the filter and it doesn't stop it.
Has anyone ran across this yet.
Thankyou
Jim

Because of the way it works the optimax sustem produces vapors into the mixing box (fuel-air) into the engine as far as i know you only have to bleed the fuel rail while the pump is pressing fuel .
Ithink that the bleeding valve is at the left of the engine it has a brass cup
sorry for my english
