On a 81 75hp Evinrude I have fuel dripping from the lower portion of the power head when I kill the engine, is it supposed to do that as some kind of way to drain excess fuel from the crankcase when the engine is not running? Doesn?t seem to be a problem while the engine is running. I have checked all the fuel lines, carb's, intake gaskets etc but no sign of a leak. Engine runs great at idle and at WOT. The fuel drips from the bolt heads that attach the crankcase head assembly to the engine. I replaced the seal and the o-ring on the crankcase head assembly but that did not fix it and no sign of fuel leaking top side and running down.
