Saturday the boat was on the river and running WOT between 4500 and 5000 rpm. I stoped it for a minute to turn around and started to head back. I gave it full throttle and the boat would not plane out or anything. At this point WOT throttle was between 2500 and 3000. I shut it down looked at the motor nothing looked out of the ordinary. Everthing was plugged up, no loose wires. I tried it again and no change. I stopped the boat left it running at idle and checked for spark. It appeared all six had fire. The boat when shut off starts right up no problem and sounds great at idle.<br /> Sunday I went and did a compression check all 6 cylnders read at 90 psi. Motor is defanitly getting gas to all six cylinders. <br /> Some of the plugs looked a little wet from gas and oil mixture. Attempted to start, started just fine. <br /> I am hoping someone here can help me get this trouble shot and help me figure it out. HELP!!!
