I have a 1977 Mercury 200 (20hp). I have had this motor for only a little while but have noticed some areas of concern. One of them is the reverse lock or lack there of. <br /><br />Here is my situation and you can help me find a solution to the problems. When I am untrailering the boat the motor wants to lift out of the water. (No reverse lock) Secondly, when I am at WOT and on plane and I radily decelerate the motor wants to lift out of the water until I slow to a reasonable speed or I apply the throttle.<br /><br />I have also asked about a rough idle for this motor in another post. So please help anyway possible.<br /><br />Thanks,<br /><br />Robert
