On a 1993 70hp johnson, I have changed the whole water pump, thermostat, flushed it out, and cleared the water outlet hose. I have in in a barrel and not using muffs. Water will dribble from the telltale for a few seconds then stop for a few then start again. The dribble is steaming hot. I just discovered that the water outlet needs to be moved from the bottom to the top of the motor due to air building up in it. Can I just reroute the hose over the top of the engine? Could this be what's wrong with the water flow?
