starvin for fuel

[Shad's Searay]

I have 93, sea ray 170 bowrider, 3.0 merc 4 cyl, anyway, when I had her up and running she dropped in rpm and was sputterin out of low to high idle while in gear, so I rebuilt the carb which had junk in it, and the f/w seperator which was also filthy, I took it out after that and she ran like a champ for a mile or so the the symptom came back, so I'm thinkin maybe fuel pump or somthin else clogged , anybody know where the pump is located or if there is a hidden screen I don't know about, This all started when I bought the boat from somebody after it had sat for a while, then I addad some stabil to clean it up.

Follow the fuel line from the carb ,be either mech or elec. The anti-syphon could be stuck. its the very first fitting at the gas tank.Fuel sep could be clogged again depending how much debris/water was in the gas tank.Have you done a full tuneup?

No I havent done a full tune up just know that the fluids were serviced before I bought it , I'll take a look at that fitting at the tank It's easy to get to. do ya recomend changin that rock filter for somthin different, it hasn't been touched at all, the safty wire at the bottom of the bowl still had the factory coating on it.

After 19 years it might be clogged a bit.
