I just bought a boat with a 115HP charger 4cyl and I am wondering what I should be seeing out of what holes. And what holes are "pee" holes and what's not. I am seeing exauhst out of the two highest holes on the motor. Is this an exauhst leak? Why are the holes there? Liquid cooled exauhst "pee" holes.I am also seeing water coming out of the lower exauhst exit (just a trikle)a blown head gasket? Any advice would be greatly appreciated.
