I have a 1985 Mercury XR2 150 HP. Ever since I bought the boat in 1987, the engine has stalled when I'm in gear at idle speed (trolling speed).<br /><br />It also seems to be leaking gas when just sitting out of gear in idle. You can see a thin gas slick around the motor for about 3-5 feet in diameter. Are the stalling and gas leak related?<br /><br />The fuel pump was recently replaced and it got better for about a week. Now it's stalling off and on. It coughs with kind of a chhhha sound right before it dies.<br /><br />When it stalls, the ball is soft because there is no gas in it. Once I pump the ball until it's hard again, the engine will start and run just fine.<br /><br />It's sucking in air from somewhere. I tightened all the joints between the gas tank, fuel hose, the ball, and the engine connector. I saw someone mentioned an anti-siphon valve in the gas tank pick-up-tube in another posting. Could this be the problem? How will I recognize the anti-siphon valve?
