Problem with white smoke/steam
Carried out loads of work such as cleaning heat exchanger , oil cooler ,changed thermostats,cleaned all pipes in connection with above , cleaned out exhaust elbow
No signs of water leak on side of engine but tops up freshwater side before trip but somehow it gets into the hull by time I back in ,
I have tasted the water in the hull and definitely fresh
Temperature reading is normal at all times but at 2900 rpm can notice white steam /smoke 3200-3500 revs and it’s a lot worse but disappears in no time
