"5.7L Merc. Impeller one year
"5.7L Merc. Impeller one year old. New thermostat. Only run 1XWeek. At dock runs almost a perfect 175. On the lake fluctuates 125-175, up and down frequently. I had notice once some water come out of water pump but stopped when engine warmed up, nothing since. Bad pump? Impeller? Air in system?"
