MJ. second what ferm said, my merc runs 15 to 20 degrees hotter when between 1500 & 2500 rpms. they really don't seem to like trolling. I'm assuming you taken the oil injection system off, if not , that might be a prob. on hitting the choke, not sure if those carbs have a butterfly or a gas pump that pumps a shot of gas to the carb. might make a difference to what spare was checking
