Hello, I've been doing some troubleshooting on my dads 25' Sea Fox with twin 150's. He made the mistake of letting it sit for about two years with half a tank of fuel. Went to get it ready for this season, and neither engine would crank. Got all water and bad fuel out of fuel tank, replaced lines from tank to engine, checked all fuel lines on engines,disassembled fuel rails to check for debris, replaced all spark plugs, fuel filters. Got the engines running, and the starboard engine idles and runs great IP to about 3k rpm then starts cutting in and out like its starving for fuel. I haven't had a way to check fuel/air pressures yet, but my first question is- are there any fuel filters/strainers other than the obvious one next to the VST? Just want to make sure before I start looking for failed parts. Thank you all.
