I have a 1995 Mariner Outboard on my Boat. I have just recently purchased it. I took it to the lake and for most of the day all was fine. However when I decided to call it a day and head for the boat ramp. I pushed the controls forward and the boat started to PLANE then all of a sudden the RPM went to just over 6000 rpm and acted as if it were suddenly out of gear, but after decreasing speed it ran ok until I tried planing again. Same thing, it would plane for about 25 feet then RPM ran up and it quit planing. It was still in gear when speed was reduced.<br />ANY HELP WOULD BE APPRECIATED, Newbi to Mariner/Mercury Outboards.<br />Thanks, Elikk
