"Have twin Yamaha F250's with 120 hrs Got a "water in fuel" alarm on one engine. Checked the engine filter cup and looked full. Following directions in manual, but filter cup seemed hard to unscrew by hand and did not want to break. There was a small hole in bottom for allens wrench? Is there a tool I should use to remove or is it usually just hard to do? Also, should I replace the fuel seperator filters (10 micron) again? Just did this 1 months ago. Thanks, great engines, but still learning how to take care of them."

I have to use some larger pliers to remove mine. the plastic cup is usually pretty tight and a bit hard to turn. when you replace it put a dab of grease on the cup threads and the o-ring and it can make it easier to remove next time.
