Again, I just don’t want you to overlook that darn overboard cooling telltale. Does this engine show signs of overheating? Or, is it possible that there is just some debris getting caught intermittently in the telltale elbow/nipple. Again, don’t try to unthread that plastic elbow from the exhaust manifold, it will probably snap off and create a mess for you.
So, this engine has the thru hub gearcase with the shift rod that goes through the impeller housing, correct? That shift rod must be properly sealed through the impeller housing or there will be an air leak into the pump, especially at high speeds. Post some pictures if you have questions, this procedure is kind of hard to explain on paper.
