Hi, <br />I have twin 55hp Tohatsu's on a 17ft half cabin Fibreglass hull, I only just purchased the boat, I have taken the boat out twice, and twice both outboards turned off on me while cruising, they both turn off at once, one fuel bulb goes flat while the other remains hard, I open the fuel tank and check for fuel and a couple of other things, then one motor will start and the other won't (it will kick over continously but won't start).<br />If i leave alone for about 10 min engines will start fine and first go. Out of the water both engines start fine. and idle quite well.<br />I emptied the fuel and cleaned it, I found one small sheet of thread tape inside about 7 cms long, and nothing else. I put fresh fuel, but I noticed that when I pump the bulbs, one goes hard and the other remains a little softer, both engines started fine but I haven't been in the water yet to test it. any other ideas?? Am I on the right track, does it sound like it's fuel related??<br /><br />Motors are about 1985 model...the breather on the fuel tank lid is open and the tank has another breather whole that comes out the back of the boat.
