I have noticed that the exhaust that is coming out of the relief vents is not the same on both sides. Is this normal??
I have the muffs on and the outdrive in the down position and running at 1200 rpm. There is cool to warm air only coming out of the port side vent and very hot water and exhause coming out of the starboard vent. There is only a small amount of exhaust coming out of the prop. What is normal??? I am trying to make sure I don't have an exhaust problem.
