Hi- Hopefully someone can help me. I have an 1997 Ficht 150 (E150ILEUC/G04283431) and I need to replace the screw on fuel filter/water seperator. This boat is new to me. The prior owner has a Sierra brand (# I can't read) on it now. I have read that the Ficht's take a specific fuel filter. Can anyone suggest the correct one(s) I should use? Should it be OMC or is Sierra (or other off brand) OK to use. Any help would be appreciated. Thanks- Steve.
