1984 Evinrude 150 Mod# EISOTLCRD, S/N J0421990, runs great under partial load but breaks down at full throttle, what should I look for first?
Thanks

Check your plugs on each bank and check electrode color look for a cocoa brown on the tip. Sounds like a pack maybe breaking down. Got a particular RPM it starts at?
