I have a problem maybe someone can tell em whats wrong .. First off its a 1995 Sea pro W/A with a mercruiser 3.0lx with an Alpha 1 While cruising I heard a loud almost "tapping"" or "clinking noise" then I lost power gradually I stopped and went again and it happenned again it eventually got worse now it happens when i throttle up at all all the time. WOT is 3000 rpms instead of 4100 and top speed is 13 mph instead of 31 with a 19p prop the engine is under stress the noise sounds like it is coming from the back of the engine near the stern drive to the right looking at it from the front when I rev the engine in Nuetral the engine sounds fine just when it is in gear and there is no problem shifting into reverse the noise is sporadic so its not like a card in a bike spoke type of thing Any ideas ?? Thanx in advance
