"I have a '94 Mercury 75 h
"I have a '94 Mercury 75 hp outboard that runs fine for about 20 minutes, then drops off power and will not let me get it back on plane. I can go clutch speed around the lake for hours but it will not go back on plane. This is now my third time back to the boat yard, they replaced the propeller hub the first time and throttle cables/adjusted the timing the second. Any one have any thoughts? Neither of these repairs fixed the problem."
