I got a 2000 Baja 232 with a mild built 502. Saturday I went out topped off fuel (10 gallons). Fired boat and she did fine. I was cruising @ 50 and it started losing power and bucking (like water in fuel). It starts and idles fine. At the end of the day we headed back and at full throttle it would not get passed 20mph. Then it would get full power then back to less power it did this several time until it felt like whatever was in the fuel it worked it’s way out and the rest of the trip back she ran as normal. I use fuel stabilizer every year before Storage. Fuel pump is new. I was thinking maybe an injector got clogged. Could I use some bg 44k fuel cleaner? I guess I would need 3 bottles since I have 74 gallon tank. Does anyone have idea or had this happen to them?
Thanks for reading.

Ahh good idea! Thanks

Ok. Thanks guys

So I Swapped our the fuel water separator. I took the boat out 2 days and drove it around. It’s starts and idles no problem. At small increments of throttle it stays normal at middle throttle it run as if there is something in the fuel cuts in full power then cuts out again. I ran it all day Sat and Sunday. My next thought is pulling the pump out and looking to see if the filter is clogged. Any other suggestions?

I put it a cup and looked fine to me. I’ll check the fuel pressure and report back.

if it’s the stock pump I don’t think they had a screen/filter at the pump till 01 on the 496’s
