Anyone have and idea why a 1996 40TRLU 2 stoke would lose power after 1-3 min running high RPM on the water. Seems to take off great, but after 1-3 min of running high speed, the RPM/speed slows to @ 3000 rpm and doesn't go any faster 5-7mph. Took off air cleaner and watched fuel entering carbs and it doesn't fluctate. It's almost as if a cyclinder is down, but if I pull a plug wire you can tell difference. It almost feels like cavitation, but the boat planes out great when it starts off and runs great for a minute, then begins to just slows down. Changed plugs, no help.
