Thanks everyone. I appreciate the help.Hi:
I have a 1998 Shamrock 22 WA. Engine is the Pleasurecraft 351. There are two new (past five years) 40 gallon fuel tanks. Last week I was out for a couple of hours and on return, just at the fairway to the anchorage, the engine quit. First thought was that I ran out of gas. Got towed to gas dock. Port side tank only took about 2 gallons. Starboard side took 40 gallons. So I didn't run out of gas. Obviously, the fuel in the port side tank is not going anywhere and I do not know why. The two cutoff switches at the fuel filter/water separator are both open. About 4 weeks ago, engine would not start. Before determining that the fuel pump and fuel filter/water separator needed replacement, I removed the deck boards exposing the two fuel tanks. Checked fuel hoses and anti siphon valves for both tanks and no blockage.
Anyone have an idea what might be the problem? Also, am I correct that each tank empties at the same time? This would seem to make sense otherwise the boat would be unbalanced if each tank drained separately.
