Sorry to be so dumb, but where is the pee hole located on a 1971 20 h.p mercury. Want to be sure it's clear before replacing impeller and thermastat.<br />Thank you for your help.
Well if all else fails, remove the cowl and look for the cover on the exhaust water jacket; big flat plate usually on the Port (left) side (facing forward). The Pee hole tube attaches there and runs to a vent overboard, usually on the starboard side as that is where the operator usuallysitting; tiller or console steering; doesn't matter.<br /><br />Mark
