"I have a 1997 Mercury V6 EFI
"I have a 1997 Mercury V6 EFI 150 HP. Starts fine, runs great at idle. When I increase idle past 1200 rpm the boat wants to lunge. It lunges then backs off then lunges and backs off. It does not die. No horns go off. When I back off the throttle the boat cruises at slow idle perfectly. I suspect fuel related problem. I took off the fuel seperator filter and dumped into a pan. No water in the fuel and fuel was clean. The boat has a hand pump primer bulb and gets hard when pumped. Seems to hold pressure. Now that I have replaced the seperator filter as per manual the bulb stays collapsed after squeezing. Maybe the fuel pump needs to be running. Not sure. Is there a fuel filter inside the VST? If so how do I change this? Please advise me of problem or ask questions.
Thank you,
