I have a 3.0L I/O mercruiser with Alpha one outdrive. I took the boat out on the lake the other day and was having problem getting a steady rpm running. Done all the pre boating stuff the night before (starting the engine with muff on to check that everything is in working condition). In the morning around 11:00am when I took the boat to the lake and launch it. Initially when turning the start switch there was no engine turning over. After a couple of try the was a clicking sound and engine still would not start. Wait a minute and tried again and still nothing and on the 3rd try the starter engage and the engine turn over. Left it at idle for about 5 minutes to get the engine warm and was running fine. <br /><br />Took the boat out and was running fine and out on plane at around 3000rpm. About 400 or 500 yards out into the lake the engine rpm keep climbing and the speed drop and was out of plane pretty quick. Meanwhile, rpm is still climbing until I took the engine out of gear and the rpm got down to idling range. I left it idling for a few minute and and then put it back into gear and the rpm was steady after that. <br /><br />Don't know where to begin to trouble shoot this problem. Any help is appreciated.<br /><br />Thanks
