Had a hydro lock situation, saltwater in all 6, pulled the block, new pistons n polished crank. Put it back together, new t-stat hsg as well, started right up but not smooth like the Stbd engine, but it's like its running fat, only on the port side where the manifold is getting hot, like no water going to the manifold, but, checked the elbow and the pipe is clear, and water is flowing but not sure if it's to full volume, I pinched off the stbd pipe to that manifold and the port side did seem to cool off a bit. Something isnt right, pulled the plugs, stbd side nice and normal, port side, a little carbon (black) and some brownish flat textured discoloration on insulator and bridge. seems like a little salt water is getting in there somehow. The flappers seem to be fine, no stiction there, possibly an obstruction on the way out or low volume in from the skeg (Alpha). Looking for suggestions what to check next. Thanks, Greg
