200 HP Pro XS sn 2B121334. I seem to have an issue with taking the motor out of gear either from forward or reverse. It goes in gear fine but hangs up trying to take it out and I really have to put some pressure on it. This is a new lower unit as Mercury replaced my last one under warranty but I had the same issue with the old one. Noticed that my hot foot doesn't come back the last 1/4 of an inch to the stop bolt. If I turn the nut clockwise on the spring will that bring it the rest of the way and slow the idle down? I idle about 3 to 4 mph now. Thanks.
