Hi - You guys have been a great help in getting my boat back on the water this year - However, one last problem has me stumped. I have a 1982 OMC 2.5L I/O with a Stringer outdrive. 2 barrel Rochester carb, open freeshwater cooling, and fixed trim. Symptoms: After running open throtle for about 30 minutes the engine starts to cut out(miss) then die. I can throtle back to idle and the engine will run fine. Go back to full speed and it dies again in about 5 minutes. Sounded liek a fuel problem. I replaced the fuel pump (mechanical), checked the fuel lines, rebuilt the carb and added a new float. I still have the problem! It only does this after running for a while so it might be heat related. Oil level and pressure is fine, Cooling temp is normal, unit is charging, no smoke, noises, or sounds... just dies. Strange thing is it runs great for the first 30-45 minutes. Help!
