My 87 Merc 150 is now setting off alarms.<br /><br />When I put it away for the winter, she was running perfect. Last week I took her out. I started getting a very light beep almost a scratching sound. Once I got the revs up it stoped. But then periodically started again.<br /><br />Today I took her out again. Within 1 minute of pulling out of the dock. The alarm became a blaring loud scream. I immediately stoped, waited 20 secs or so and started it up. It went right to the alarm again.<br /><br />One thing I did notice, is that varying the RPM seemed to make it go away for short stints. Keeping it at idle sometines did not make the alarm go. Also, leaning the boat into a turn or hiting some light chop made it want to stop.<br /><br />What does this sound like ?<br /><br />Thanks John
